6 / 11 page 6 FN6091.1 November 3, 2004 Detailed Description The ISL43L12X family of devices are bidirectional, single pole/single throw (SPST) analog switches that offer precise switching capability from a single 1.65V to 3.6V supply with low on-resistance (0.16 Ω) and high speed operation (tON = 13ns, tOFF = 13ns). The device is especially well suited for portable battery powered equipment due to its low operating supply voltage (1.65V), low power consumption (2.7 µW max), low leakage currents (80nA max), and the tiny TDFN and MSOP packaging. The ultra low on-resistance and RON flatness provide very low insertion loss and distortion to application 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 7). 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 Ω resistor in series with the input (see Figure 7). 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. FIGURE 3.
