1 60v fault protected, 5v, rs-485/rs-422 transceivers with 25v cmr and esd protection isl32490e, ISL32492E, isl324 93e, isl32495e, isl32496e, isl32498e the isl32490e, ISL32492E, isl32493e, isl32495e, isl32496e, isl32498e are fault protected, 5v powered, differential transceivers that exceed the rs-485 and rs-422 standards for balanced communica tion. the rs-485 transceiver pins (driver outputs and receiver inputs) are fault protected up to 60v and are protected against 16.5kv esd strikes without latch-up. additionally, the extended common mode range allows these transceivers to operate in environments with common mode voltages up to 25v (>2x the rs-485 requirement), making this fault protected rs-485 family one of the most robust on the market. transmitters (tx) deliver an exceptional 2.5v (typical) differential output voltage into the rs-485 specified 54 ? load. this yields better noise immunity than standard rs-485 ics or allows up to six 120 ? terminations in star network topologies. receiver (rx) inputs feature a ?full fail-safe? design that ensures a logic high rx output if rx inputs are floating, shorted, or on a terminated but undriven (idle) bus. rx outputs have high drive levels; typically, 15ma @ v ol = 1v (for opto-coupled, isolated applications). half duplex (rx inputs and tx outputs multiplexed together) and full duplex pinouts are available. see table 1 on page 2 for key features and configurations by device number. for fault protected or wide common mode range rs-485 transceivers with cable invert (polarity reversal) pins, please see the isl32483e data sheet. features ? fault protected rs-485 bus pins . . . . . . . . . . . . . . up to 60v ? extended common mode range . . . . . . . . . . . . . . . . . . . 25v more than twice the range required for rs-485 ? 16.5kv hbm esd protection on rs-485 bus pins ? 1/4 unit load for up to 128 devices on the bus ? high transient overvoltage tolerance . . . . . . . . . . . . . . . 80v ? full fail-safe (open, short, terminated) rs-485 receivers ?high rx i ol for opto-couplers in isolated designs ? hot plug circuitry; tx and rx outputs remain three-state during power-up/power-down ? choice of rs-485 data rates. . . . . . . . . 250kbps to 15mbps ? low quiescent supply current . . . . . . . . . . . . . . . . . . . 2.3ma ? ultra low shutdown supply current . . . . . . . . . . . . . . . . 10a applications ? utility meters/automated meter reading systems ?high node count rs-485 systems ? profibus? and rs-485 base d field bus networks, and factory automation ?security camera networks ? building lighting and environmental control systems ? industrial/process control networks figure 1. exceptional rx operates at >15mbps even with a 25v common mode voltage figure 2. isl3249xe delivers superior common mode range vs standard rs-485 devices time (20ns/div) voltage (v) -5 0 5 10 15 20 25 30 b v id = 1v a ro isl3249xe common mode range closest competitor standard rs-485 transceiver -25 -20 -12 -7 0 12 25 march 16, 2012 fn7786.2 caution: these devices are sensitive to electrostatic discharge; follow proper ic handling procedures. 1-888-intersil or 1-888-468-3774 | copyright intersil americas inc. 2011, 2012. all rights reserved intersil (and design) is a trademark owned by intersil corporation or one of its subsidiaries. all other trademarks mentioned are the property of their respective owners.

requirement of 1ma maximum. thus, these products are known as ?one-quarter ul? transceivers, and there can be up to 128 of these devices on a network while still complying with the rs-485 loading specification. the rx functions with common mode voltages as great as 25v , making them ideal for industrial or long networks where induced voltages are a realistic concern. all the receivers include a ?full fail -safe? function that guarantees a high-level receiver output if the receiver inputs are unconnected (floating), shorted together, or connected to a terminated bus with all the transmitters di sabled (i.e., an idle bus). rx outputs feature high drive levels (typically 22ma @ v ol =1v) to ease the design of optically coupled isolated interfaces. receivers easily meet the data rates supported by the corresponding driver, and all rece iver outputs are three-statable via the active low re input. the rx in the 250kbps and 1mbps versions include noise filtering circuitry to reject high-frequency signals. the 1mbps version typically rejects pulses narrower than 50ns (equivalent to 20mbps), while the 250kbps rx rejects pulses below 150ns (6.7mbps). driver (tx) features the rs-485/rs-422 driver is a diff erential output device that delivers at least 1.5v across a 54 ? load (rs-485) and at least 2.4v across a 100 ? load (rs-422). the drivers feature low propagation delay skew to maximize bit width and minimize emi, and all drivers are three-statable via the active high de input. the 250kbps and 1mbps driver outputs are slew rate limited to minimize emi and to minimize reflections in unterminated or improperly terminated networks . outputs of the isl32496e and isl32498e drivers are not limited; thus, faster output transition times allow data rates of at least 15mbps. high overvoltage (fault) protection increases ruggedness note: the available smaller pitch package (msop) may not meet the creepage and clearance (c&c) requirements for 60v levels. the user is advised to determine his c&c requirements before selecting a package type. the 60v (referenced to the ic gnd) fault protection on the rs-485 pins makes these transceivers some of the most rugged on the market. this level of protection makes the isl3249xe perfect for applications where power (e.g., 24v and 48v supplies) must be routed in the conduit with the data lines, or for outdoor applications where large transients are likely to occur. when power is routed with the data lines, even a momentary short between the supply and data lines will destroy an unprotected device. the 60v fault levels of this family are at least five times higher than the levels specified for standard rs-485 ics. the isl3249xe protection is active whether the tx is enabled or disabled, and even if the ic is powered down. if transients or voltages (inc luding overshoots and ringing) greater than 60v are possible, then additional external protection is required. widest common mode voltage (cmv) tolerance improves operating range rs-485 networks operating in industrial complexes or over long distances are susceptible to large cmv variations. either of these operating environments may suffer from large node-to-node ground potential differences or cmv pickup from external electromagnetic sources, and devices with only the minimum required +12v to -7v cmr may malfunction. the isl3249xe?s extended 25v cmr is the widest av ailable, allowing operation in environments that would overwhelm lesser transceivers. additionally, the rx will not phase invert (erroneously change state), even with cmvs of 40v or differential voltages as large as 40v. high v od improves noise immunity and flexibility the isl3249xe driver design delivers larger differential output voltages (v od ) than the rs-485 standard requires or than most rs-485 transmitters can deliver. the typical 2.5v v od provides more noise immunity than networks built using many other transceivers. another advantage of the large v od is the ability to drive more than two bus terminations, which allows for utilizing the isl3249xe in ?star? and other multi-terminated, nonstandard network topologies. figure 10 on page 14 details the transmitter?s v od vs i out characteristic and includes load lines for four (30 ? ) and six (20 ? ) 120 ? terminations. figure 10 shows that the driver typically delivers 1.3v into six terminations, and the ?electrical specifications? on page 5 guarantees a v od of 0.8v at 21 ? over the full temperature range. the rs-485 standard requires a minimum 1.5v v od into two terminations, but the isl3249xe deliver rs-485 voltage levels with 2x to 3x the number of terminations. hot plug function when a piece of equipment powers up, there is a period of time during which the processor or asic driving the rs-485 control lines (de, re ) is unable to ensure th at the rs-485 tx and rx outputs are kept disabled. if the equipment is connected to the bus, a driver activating premat urely during power-up may crash the bus. to avoid this scenario, the isl3249xe devices incorporate a ?hot plug? function. circuitry monitoring v cc ensures that, during power-up and power-down, the tx and rx outputs remain disabled, regardless of the state of de and re , if v cc is less
isl32490e, ISL32492E, isl32493e, isl32495e, isl32496e, isl32498e 13 fn7786.2 march 16, 2012 than 3.5v. this gives the processor/as ic a chance to stabilize and drive the rs-485 control lines to the proper states. figure 9 illustrates the power-up and power-down performance of the isl3249xe compared to an rs-485 ic without the hot plug feature. esd protection all pins on these devices incl ude class 3 (>8kv) human body model (hbm) esd protection struct ures that are good enough to survive esd events commonly seen during manufacturing. even so, the rs-485 pins (driver outputs and receiver inputs) incorporate more advanced struct ures, allowing them to survive esd events in excess of 16.5kv hbm (15kv for full-duplex version). the rs-485 pins are particularly vulnerable to esd strikes because they typically conne ct to an exposed port on the exterior of the finished product. simply touching the port pins or connecting a cable can cause an esd event that might destroy unprotected ics. these new esd structures protect the device whether or not it is powered up, and without interfering with the exceptional 25v cmr. this bu ilt-in esd protection minimizes the need for board-level protecti on structures (e.g., transient suppression diodes) and the asso ciated, undesirable capacitive load they present. data rate, cables, and terminations rs-485/rs-422 are intended for network lengths up to 4000 feet, but the maximum system data rate decreases as the transmission length increases. devices operating at 15mbps may be used at lengths up to 150 feet (46m), but the distance can be increased to 328 feet (100m) by operating at 10mbps. the 1mbps versions can operate at full data rates with lengths up to 800 feet (244m). jitter is the limiting parameter at these faster data rates, so employing encoded data streams (e.g., manchester coded or return-to-zero) may allow increased transmission distances. the sl ow versions can operate at 115kbps or less at the full 4000-foot (1220m) distance or at 250kbps for lengths up to 3000 feet (915m). dc cable attenuation is the limiting parame ter, so using better quality cables (e.g., 22 awg) may allow increased transmission distance. twisted pair is the cable of choice for rs-485/rs-422 networks. twisted pair cables tend to pick up noise and other electromagnetically induced volt ages as common mode signals, which are effectively rejected by the differential receivers in these ics. proper termination is imperative, when using the 15mbps devices, to minimize reflecti ons. short networks using the 250kbps versions need not be terminated; however, terminations are recommended unless power dissipation is an overriding concern. in point-to-point or point-to-multipoint (single driver on bus, like rs-422) networks, the main cable should be terminated in its characteristic impedance (typically 120 ? ) at the end farthest from the driver. in multi-receiver applications, stubs connecting receivers to the main cable should be kept as short as possible. multipoint (multi-driver) systems require that the main cable be terminated in its characteristic impedance at both ends. stubs connecting a transceiver to the ma in cable should be kept as short as possible. built-in driver overload protection as stated previously, the rs-485 specification requires that drivers survive worst-case bus contentions undamaged. these transceivers meet this requiremen t via driver output short circuit current limits and on-chip thermal shutdown circuitry. the driver output stages incorporate a double foldback, short circuit current limiting scheme, which ensures that the output current never exceeds the rs-485 specification, even at the common mode and fault condition voltage range extremes. the first foldback current level ( 70ma) is set to ensure that the driver never folds back when driving loads with common mode voltages up to 25v. the very low second foldback current setting ( 9ma) minimizes power dissipation if the tx is enabled when a fault occurs. in the event of a major short circui t condition, devices also include a thermal shutdown feature that di sables the drivers whenever the die temperature becomes excessive. this eliminates the power dissipation, allowing the die to cool. the drivers automatically re-enable after the die temperature drops about +15c. if the contention persists, the thermal shutdown/re-enable cycle repeats until the fault is cleared. receiver s stay operational during thermal shutdown. low power shutdown mode these bicmos transceivers all use a fraction of the power required by competitive devices, but they also include a shutdown feature that reduce s the already low quiescent i cc to a 10a trickle. these devices enter shutdown whenever the receiver and driver are simultaneously disabled (re =v cc and de = gnd) for a period of at least 600ns. disabling both the driver and the receiver for less than 60ns guarantees that the transceiver will not enter shutdown. note that receiver and driver enable times increase when the transceiver enables from shutdown. refer to notes 9, 10, 11, 12 and 13, at the end of the ?electrical specifications?
