1 ? fn6098.1 isl43l420 ultra low on-resistance, +1.1v to +4.5v single supply, quad spdt (dual dpdt) analog switch the intersil isl43l420 device is a low on-resistance, low voltage, bidirectional, quad spdt (dual dpdt) analog switch designed to operate from a single +1.1v to +4.5v supply. targeted applications include battery-powered equipment that benefit from low r on (0.24 ?) and fast switching speeds (t on =8ns, t off = 5ns). the digital logic input is 1.8v logic-compatible when using a single +3v supply. cell phones, for example, often face asic functionality limitations. the number of anal og input or gpio pins may be limited and digital geometries are not well suited to analog switch performance. this part may be used to ?mux-in? additional functionality while reducing asic design risk. the isl43l420 is offered in a small form factor package, alleviating board space limitations. the isl43l420 is a committed quad spdt that consists of four normally open (no) and four normally (nc) switches. this configuration can also be used as a diff dual 2-to-1 multiplexer/demultiplexer or a dual 2-to1 multiplexer/demultiplexer. the isl43l420 is pin compatible with the stg3699. related literature ? technical brief tb363 ?guidelines for handling and processing moisture sensitive surface mount devices (smds)? ? application note an557 ?recommended test procedures for analog switches? features ? drop in replacement for the stg3699 ? on resistance (r on ) - v+ = +4.3v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.24 ? - v+ = +3.0v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.26 ? - v+ = +1.8v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.45 ? ?r on matching between channels . . . . . . . . . . . . . . . . .0.05 ? ?r on flatness across signal range . . . . . . . . . . . . . . .0.05 ? ? single supply operation. . . . . . . . . . . . . . . . . +1.1v to +4.5v ? low power consumption (pd). . . . . . . . . . . . . . . . . . <0.2w ? fast switching action (v+ = +4.3v) -t on . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8ns -t off . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5ns ? guaranteed break-before-make ? 1.8v logic compatible (+3v supply) ? available in 16 lead 3x3 qfn ? esd hbm rating - com pins . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9kv - all other pins . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4kv ? pb-free available as an option (see ordering info) applications ? battery powered, handheld, and portable equipment - cellular/mobile phones - pagers - laptops, notebooks, palmtops ? portable test and measurement ? medical equipment ? audio and video switching table 1. features at a glance isl43l420 number of switches 4 sw quad spdt (dual dpdt) 4.3v r on 0.24? 4.3v t on /t off 8ns/5ns 3.0v r on 0.26? 3.0v t on /t off 10ns/7ns 1.8v r on 0.45? 1.8v t on /t off 18ns/10ns packages 16 ld 3x3 qfn data sheet caution: these devices are sensitive to electrosta tic discharge; follow proper ic handling procedures. 1-888-intersil or 321-724-7143 | intersil (and design) is a registered trademark of intersil americas inc. copyright intersil americas inc. 2004. all rights reserved all other trademarks mentioned are the property of their respective owners. february 18, 2005

8 fn6098.1 detailed description the isl43l420 is a bidirectional, quad single pole/double throw (spdt) analog switch that offers precise switching capability from a single 1.1v to 4.5v supply with low on- resistance (0.24 : ) and high speed operation (t on = 8ns, t off = 5ns). the device is especially well suited for portable battery powered equipment due to its low operating supply voltage (1.1v), low power consumption (2.7 p w max), low leakage currents (150na max), and the tiny qfn package. the ultra low on-resistance and r on flatness provide very low insertion loss and distortion to applications that require signal reproduction. supply sequencing and overvoltage protection with any cmos device, proper power supply sequencing is required to protect the device from excessive input currents which might permanently damage the ic. all i/o pins contain esd protection diodes from the pin to v+ and to gnd (see figure 8). to prevent forward biasing these diodes, v+ must be applied before any input signals, and the input signal voltages must remain between v+ and gnd. if these conditions cannot be guaranteed, then one of the following two protection methods should be employed. logic inputs can easily be protected by adding a 1k : resistor in series with the input (see figure 8). the resistor limits the input current below the threshold that produces permanent damage, and the sub-microamp input current produces an insignificant voltage drop during normal operation. this method is not acceptable for the signal path inputs. adding a series resistor to the switch input defeats the purpose of using a low r on switch, so two small signal diodes can be added in series with the supply pins to provide overvoltage protection for all pins (see figure 8). these additional diodes limit the analog signal from 1v below v+ to 1v above gnd. the low leakage current performance is unaffected by this approach, but the switch signal range is reduced and the resistance may increase, especially at low supply voltages. power-supply considerations the isl43l420 construction is typical of most single supply cmos analog switches, in that they have two supply pins: v+ and gnd. v+ and gnd drive the internal cmos switches and set their analog vo ltage limits. unlike switches with a 4v maximum supply voltage, the isl43l420 4.7v maximum supply voltage provides plenty of room for the 10% tolerance of 4.3v supplies, as well as room for overshoot and noise spikes. the minimum recommended supply voltage is 1.1v. it is important to note that the input signal range, switching times, and on-resistance degrade at lower supply voltages. refer to the electrical specification tables and typical performance curves for details. figure 6. crosstalk test circuit figure 7. capacitance test circuit test circuits and waveforms (continued) 0v or v+ analyzer v+ c no or nc signal generator r l gnd in 1 com 50 : n.c. com nc or no v+ c gnd no or nc com in impedance analyzer 0v or v+ figure 8. overvoltage protection gnd v com v no or nc optional protection v+ in x diode optional protection diode optional protection resistor isl43l420
9 fn6098.1 v+ and gnd also power the internal logic and level shifters. the level shifters convert the in put logic levels to switched v+ and gnd signals to drive the analog switch gate terminals. this family of switches c annot be operated with bipolar supplies, because the input switching point becomes negative in this configuration. logic-level thresholds this switch family is 1.8v cmos compatible (0.5v and 1.4v) over a supply range of 2.0v to 3.6v (see figure 16). at 3.6v the v ih level is about 1.27v. this is still below the 1.8v cmos guaranteed high output minimum level of 1.4v, but noise margin is reduced. the digital input stages draw supply current whenever the digital input voltage is not at one of the supply rails. driving the digital input signals from gn d to v+ with a fast transition time minimizes power dissipation. high-frequency performance in 50 : systems, the signal response is reasonably flat even past 30mhz with a -3db bandwidth of 104mhz (see figure 19). the frequency response is very consistent over a wide v+ range, and for varying analog signal levels. an off switch acts like a capacitor and passes higher frequencies with less attenuation, resulting in signal feedthrough from a switch?s input to its output. off isolation is the resistance to this feedthrough, while crosstalk indicates the amount of feedthrough from one switch to another. figure 20 details the high off isolation and crosstalk rejection provided by this part. at 100khz, off isolation is about 68db in 50 : systems, decreasing approximately 20db per decade as frequency increases. higher load impedances decrease off isolation and crosstalk rejection due to the voltage divider action of the switch off impedance and the load impedance. leakage considerations reverse esd protection diodes are internally connected between each analog-signal pin and both v+ and gnd. one of these diodes conducts if any analog signal exceeds v+ or gnd. virtually all the analog leakage current comes from the esd diodes to v+ or gnd. although the esd diodes on a given signal pin are identical and therefore fairly well balanced, they are reverse biased differently. each is biased by either v+ or gnd and the analog signal. this means their leakages will vary as the signal varies. the difference in the two diode leakages to the v+ and gnd pins constitutes the analog- signal-path leakage current. all analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. this is why both sides of a given switch can show leakage curren ts of the same or opposite polarity. there is no connection between the analog signal paths and v+ or gnd. typical performance curves t a = 25c, unless otherwise specified figure 9. on resistance vs supply voltage vs switch voltage figure 10. on resistance vs supply voltage vs switch voltage 012345 0.18 0.19 0.2 0.21 0.22 0.23 0.24 0.25 0.26 0.27 0.28 0.29 0.3 0.31 r on ( : ) v com (v) i com = 100ma v+ = 3v v+ = 2.7v v+ = 4.3v v+ = 3.6v r on ( : ) v com (v) 00.511.52 0 0.5 1 1.5 2 2.5 3 i com = 100ma v+ = 1.5v v+ = 1.1v v+ = 1.8v v+ = 1.65v isl43l420
