Data Sheet April 27, 2006 FN6011.5
15kV ESD Protected, +3V to +5.5V, 1Microamp, 250kbps, RS-232 Transmitters/Receivers
The Intersil ISL83220E is a 3.0V to 5.5V powered RS-232 transmitter/receiver which meets ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Additionally, it provides 15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are PDAs, Palmtops, and notebook and laptop computers where the low operational, and even lower standby, power consumption is critical. Efficient on-chip charge pumps, coupled with a manual powerdown function, reduce the standby supply current to a 1A trickle. Small footprint packaging, and the use of small, low value capacitors ensure board space savings as well. Data rates greater than 250kbps are guaranteed at worst case load conditions. This family is fully compatible with 3.3V only systems, mixed 3.3V and 5.0V systems, and 5.0V only systems. Table 1 summarizes the features of the ISL83320E, while Application Note AN9863 summarizes the features of each device comprising the ICL32XXE 3V family.

Detailed Description
The ISL83220E operates from a single +3V to +5.5V supply, guarantees a 250kbps minimum data rate, requires only four small external 0.1F capacitors, features low power consumption, and meets all ElA RS-232C and V.28 specifications. The circuit is divided into three sections: The charge pump, the transmitter, and the receiver.
these transmitters deliver true RS-232 levels over a wide range of single supply system voltages. The transmitter output disables and assumes a high impedance state when the device enters the powerdown mode (see Table 2). This output may be driven to 12V when disabled. All devices guarantee a 250kbps data rate for full load conditions (3k and 1000pF), VCC 3.0V. Under more typical conditions of VCC 3.3V, RL = 3k, and CL = 250pF, the ISL83220E easily operates at 900kbps. Transmitter inputs float if left unconnected, and may cause ICC increases.
Charge-Pump
Intersil's new 3.3V family utilizes regulated on-chip dual charge pumps as voltage doublers, and voltage inverters to generate 5.5V transmitter supplies from a VCC supply as low as 3.0V. This allows these devices to maintain RS-232 compliant output levels over the 10% tolerance range of 3.3V powered systems. The efficient on-chip power supplies require only four small, external 0.1F capacitors for the voltage doubler and inverter functions, even at VCC = 3.3V. The charge pumps operate discontinuously (i.e., they turn off as soon as the V+ and V- supplies are pumped up to the nominal values), resulting in significant power savings.
Receivers
The ISL83220E device contains a standard inverting receiver that three-states via the EN control line. Receivers convert RS-232 signals to CMOS output levels and accept inputs up to 25V while presenting the required 3k to 7k input impedance (see Figure 1) even if the power is off (VCC = 0V). The receiver's Schmitt trigger input stage uses hysteresis to increase noise immunity and decrease errors due to slow input signal transitions.
Transmitters
The transmitters are proprietary, low dropout, inverting drivers that translate TTL/CMOS inputs to EIA/TIA-232 output levels. Coupled with the on-chip 5.5V supplies,

ISL83220E
The ISL83220E receiver disables only when EN is driven high. (see Table 2). This allows the receiver to monitor external devices, like a modem, even when the ISL83220E is in its 1A powerdown state. Standard receivers driving powered down peripherals must be disabled to prevent current flow through the peripheral's protection diodes (see Figure 2). This renders them useless for wake up functions.

Operation Down to 2.7V
ISL83220E transmitter outputs meet RS-562 levels (3.7V), at the full data rate, with VCC as low as 2.7V. RS-562 levels typically ensure interoperability with RS-232 devices.

Powerdown Functionality
This 3V family of RS-232 interface devices requires a nominal supply current of 0.3mA during normal operation (not in powerdown mode), which is considerably less than the 5mA to 11mA current required of 5V RS-232 devices. The already low current requirement drops significantly when the device enters powerdown mode. In powerdown, supply current drops to 1A, because the on-chip charge pump turns off (V+ collapses to VCC, V- collapses to GND), and the transmitter outputs three-state. This micro-power mode makes these devices ideal for battery powered and portable applications.
FIGURE 2. POWER DRAIN THROUGH POWERED DOWN PERIPHERAL
Receiver ENABLE Control
The ISL83220E also features an EN input to control the receiver output. Driving EN high disables the receiver output placing it in a high impedance state. This is useful to eliminate supply current, due to a receiver output forward biasing the protection diode, when driving the input of a powered down (VCC = GND) peripheral (see Figure 2).
Software Controlled (Manual) Powerdown
On the ISL83220E, the powerdown control is via a simple shutdown (SHDN) pin. Driving this pin high enables normal operation, while driving it low forces the IC into it's powerdown state. Connect SHDN to VCC if the powerdown function isn't needed. Note that the receiver output remains enabled during shutdown (see Table 2). For the lowest power consumption during powerdown, the receiver should also be disabled by driving the EN input high (see next section). The time to recover from manual powerdown mode is typically 100s.
Capacitor Selection
The charge pumps require 0.1F capacitors for 3.3V operation. Do not use values smaller than 0.1F. Increasing the capacitor values (by a factor of 2) reduces ripple on the transmitter outputs and slightly reduces power consumption. When using minimum required capacitor values, make sure that capacitor values do not degrade excessively with temperature. If in doubt, use capacitors with a larger nominal value. The capacitor's equivalent series resistance (ESR) usually rises at low temperatures and it influences the amount of ripple on V+ and V-.
Power Supply Decoupling
In most circumstances a 0.1F bypass capacitor is adequate. In applications that are particularly sensitive to power supply noise, decouple VCC to ground with a capacitor of the same value as the charge-pump capacitor C1. Connect the bypass capacitor as close as possible to the IC.

ISL83220E Transmitter Output when Exiting Powerdown
Figure 3 shows the response of the transmitter output when exiting powerdown mode. As it activates, the transmitter output properly goes to RS-232 levels, with no glitching, ringing, nor undesirable transients. The transmitter is loaded with 3k in parallel with 2500pF. Note that the transmitter enables only when the magnitude of the supplies exceed approximately 3V.

High Data Rates
The ISL83220E maintains the RS-232 5V minimum transmitter output voltages even at high data rates. Figure 4 details a transmitter loopback test circuit, and Figure 5 illustrates the loopback test result at 120kbps. For this test, the transmitter is driving an RS-232 load in parallel with 1000pF, at 120kbps. Figure 6 shows the loopback results for the transmitter driving 1000pF and an RS-232 load at 250kbps.

The ISL83220E directly interfaces with 5V CMOS and TTL logic families. Nevertheless, with the device at 3.3V, and the logic supply at 5V, AC, HC, and CD4000 outputs can drive ISL83220E inputs, but ISL83220E outputs do not reach the minimum VIH for these logic families.

determines an IC's ability to withstand the ESD transients typically present during handling and manufacturing. Due to the random nature of these events, each pin is tested with respect to all other pins. The RS-232 pins on "E" family devices can withstand HBM ESD events to 15kV.
COMPATIBILITY
IEC61000-4-2 Testing
Compatible with all CMOS families. Compatible with all TTL and CMOS logic families. Compatible with ACT and HCT CMOS, and with TTL. ISL83220E outputs are incompatible with AC, HC, and CD4000 CMOS inputs.
15kV ESD Protection
All pins on ISL8XXX devices include ESD protection structures, but the ISL8XXXE family incorporates advanced structures which allow the RS-232 pins (transmitter outputs and receiver inputs) to survive ESD events up to 15kV. The RS-232 pins are particularly vulnerable to ESD damage because they typically connect 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, protect without allowing any latchup mechanism to activate, and don't interfere with RS-232 signals as large as 25V.
The IEC61000 test method applies to finished equipment, rather than to an individual IC. Therefore, the pins most likely to suffer an ESD event are those that are exposed to the outside world (the RS-232 pins in this case), and the IC is tested in its typical application configuration (power applied) rather than testing each pin-to-pin combination. The lower current limiting resistor coupled with the larger charge storage capacitor yields a test that is much more severe than the HBM test. The extra ESD protection built into this device's RS-232 pins allows the design of equipment meeting level 4 criteria without the need for additional board level protection on the RS-232 port. AIR-GAP DISCHARGE TEST METHOD For this test method, a charged probe tip moves toward the IC pin until the voltage arcs to it. The current waveform delivered to the IC pin depends on approach speed, humidity, temperature, etc., so it is difficult to obtain repeatable results. The "E" device RS-232 pins withstand 15kV air-gap discharges. CONTACT DISCHARGE TEST METHOD During the contact discharge test, the probe contacts the tested pin before the probe tip is energized, thereby eliminating the variables associated with the air-gap discharge. The result is a more repeatable and predictable test, but equipment limits prevent testing devices at voltages higher than 8kV. All "E" family devices survive 8kV contact discharges on the RS-232 pins.
Human Body Model (HBM) Testing
As the name implies, this test method emulates the ESD event delivered to an IC during human handling. The tester delivers the charge through a 1.5k current limiting resistor, making the test less severe than the IEC61000 test which utilizes a 330 limiting resistor. The HBM method
