7 fn6551.2 october 26, 2009 detailed description the ISL54503 is a bi-directional, single pole/double throw (spdt) analog switch that offers precise switching capability from a si ngle 1.8v to 5.5v supply with low on-resistance (2.5 ) and high speed operation (t on = 25ns, t off = 15ns). the device is especially well suited for portable battery powered equipment due to its low operating supply voltage (1.8v), low power consumption (0.15w), low leakage currents (300na max), and the small tdfn and sot-23 packages. the low on-resistance and r on flatness provide very low insertion loss and distortion to application that requ ire signal reproduction. external v+ series resistor for improved esd and latch-up immunity intersil recommends adding a 100 resistor in series with the v+ power supply pin of the isl54050 ic (see figure 8). during an overvoltage transient event (such as occurs during system level iec 61000 esd testing), substrate currents can be generated in the ic that can trigger parasitic scr structures to turn on, creating a low impedance path from the v+ power supply to ground. this will result in a significant amount of current flow in the ic, which can potentially create a latch-up state or permanently damage the ic. the external v+ resistor limits the current during this over-stress situation and has been found to prevent latch-up or destructive damage for many overvoltage transient events. under normal operation, the sub-microamp i dd current of the ic produces an insignificant voltage drop across the 100 series resistor resulting in no impact to switch operation or performance. 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+ no or nc com in gnd v+ c v inl or v inh no or nc com in gnd v nx v 1 100ma r on = v 1 /i 1 * * i 1 = 10ma at v+ = 1.8v i 1 0v or v+ analyzer v+ c no or nc signal generator r l gnd in 1 com nc or no 50 v+ c gnd no or nc com in impedance analyzer v inl or v inh ISL54503
8 fn6551.2 october 26, 2009 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 9). 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 precautions must be implemented to prohibit the current and voltage at the logic pin and signal pins from exceeding the maximum ratings of the switch. the following two methods can be used to provide additional protection to limit the current in the event that the voltage at a signal pin or logic pin goes below ground or above the v+ rail. logic inputs can easily be protected by adding a 1k resistor in series with the input (see figure 9). 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. connecting schottky diodes to the signal pins (as shown in figure 9) will shunt the fault current to the supply or to ground, thereby protecting the switch. these schottky diodes must be sized to handle the expected fault current. power-supply considerations the ISL54503 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 voltage limits. unlike switches with a 4v maximum supply voltage, the ISL54503 5.5v maximum supply voltage provides plenty of room fo r the 10% tolerance of 3.6v supplies, as well as room for overshoot and noise spikes. the minimum recommended supply voltage is 1.8v but the part will operate with a supply below 1.8v. it is important to note that the in put signal range, switching times, and on-resistance degrade at lower supply voltages. refer to the ?electrical specifications? tables starting on page 3 and the ?typical performance curves? starting on page 10 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 analog 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 1.8v cmos compatible (0.5v and 1.4v) over a supply range of 2v to 3.6v (see figure 16). at 3.6v the v ih level is about 0.95v. 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 gnd to v+ with a fast transition time minimizes power dissipation. high-frequency performance in 50 systems, the ISL54503 has a -3db bandwidth of 250mhz (see figure 17). the frequency response is very consistent over a wide v+ range, and for varying analog signal levels. figure 8. v+ series resistor for enhanced esd and latch-up immunity in com 100 no nc v+ gnd c optional protection resistor figure 9. overvoltage protection gnd v com v nx v+ in x optional protection resistor optional schottky diode optional schottky diode ISL54503
9 fn6551.2 october 26, 2009 an off switch behaves like a capacitor and passes higher frequencies with less attenuation, resulting in signal feed-through from a switch?s input to output. off-isolation is the resistance of this signal feed-through. figure 18 details the high off-isolation provided by the ISL54503. at 1mhz, off-isolation is about 70db in 50 systems, decreasing approximately 20db per decade as frequency increases. higher load impedances decrease off-isolation due to the voltage divider action of the switch off impedance and the load impedance. leakage considerations 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 currents of the same or opposite polarity. there is no connection between the analog signal paths and v+ or gnd.
