ISL5120, isl5121, isl5122, isl5123 fn6022 rev 8.00 page 9 of 16 august 12, 2015 detailed description the ISL5120, isl5121, isl5122, isl5123 bidirectional, dual analog switches offer precise switching capability from a single 2.7v to 12v supply with low on-resistance (19 ) and high speed operation (t on = 28ns, t off = 20ns). the devices are especially well suited to portable battery powered equipment thanks to the low op erating supply voltage (2.7v), low power consumption (5w), low leakage currents (100pa max) and the tiny sot-23 packaging. high frequency applications also benefit from the wide bandwidth and the very high off isolation and crosstalk rejection. 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 gnd (see figure 8 on page 10 ). to prevent forward biasing these diodes, v+ must be applied before any input signals, and 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 submicroamp input current produces an insignificant voltage drop during normal operation. 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 figure 4. off isolation test circuit figure 5. r on test circuit figure 6. crosstalk test circuit figure 7. capacitance test circuit test circuits and waveforms (continued) analyzer r l signal generator v+ c 0v or v inh no or nc com in x gnd v+ c 0.8v or v inh no or nc com in gnd v nx v 1 r on = v 1 /1ma 1ma 0v or 2.4v analyzer v+ c no1 or nc1 signal generator r l gnd in 1 com1 in 2 50? 0v or v inh nc com2 no2 or nc2 v+ c gnd no or nc com in x impedance analyzer 0v or v inh
ISL5120, isl5121, isl5122, isl5123 fn6022 rev 8.00 page 10 of 16 august 12, 2015 limit the analog signal from 1v below v+ to 1v above gnd. the low leakage current performanc e is unaffected by this approach, but the switch resist ance may increase, especially at low supply voltages. power supply considerations the isl512x construction is typical of most cmos analog switches, except that they have only two supply pins: v+ and gnd. v+ and gnd drive the internal cmos switches and set their analog voltage limits. unlike switches with a 13v maximum supply voltage, the isl512x 15v maximum supply voltage provides plenty of room for the 10% tolerance of 12v supplies, as well as room for overshoot and noise spikes. the minimum recommended supply voltage is 2.7v. 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 starting on page 4 and typical performance curves starting on page 11 for details. v+ and gnd also power the internal logic and level shifters. the level shifters convert the input logic levels to switched v+ and gnd signals to drive the an alog switch gate terminals. this family of switches cannot be operated with bipolar supplies, because the input switching point becomes negative in this configuration. logic-level thresholds this switch family is ttl compatible (0.8v and 2.4v) over a supply range of 3v to 11v (see figure 15 ). at 12v the v ih level is about 2.5v. this is still below the ttl guaranteed high output minimum level of 2.8v, but the noise margin is reduced. for best results with a 12v supply, use a logic family the provides a v oh greater than 3v. 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 gnd to v+ with a fast transition time minimizes power dissipation. high frequency performance in 50 systems, signal response is reasonably flat even past 300mhz (see figure 16 on page 12 ). figure 16 also illustrates that the frequency response is ve ry 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 17 on page 12 details the high off isolation and crosstalk rejection provided by this family. at 10mhz, off isolation is about 50db in 50 systems, decreasing approximately 20db per decade as frequency increases. higher load impedances decrea se off isolation and crosstalk rejection due to the voltage divi der action of the switch off impedance and the load impedance. leakage considerations reverse esd protection diodes ar e internally connected between each analog-signal pin and both v+ and gnd. one of these diodes conducts if any analog si gnal exceeds v+ or gnd. virtually all the analog leakag e 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 le akage current flows between each pin and one of the supply terminals, not to the other switch terminal. this is why bo th sides of a given switch can show leakage currents of the same or opposite polarity. there is no connection between the an alog signal paths and v+ or gnd. figure 8. overvoltage protection gnd v com v no or nc optional protection v+ in x diode optional protection diode optional protection resistor
