The ISL43142 is CMOS, precision, quad analog switches designed to operate from a single +2V to +12V supply or from a ±2V to ±6V supply. Targeted applications include battery powered equipment that benefit from the devices’ low power consumption (1uW), low leakage currents (1nA max), and fast switching speeds (tON = 30ns, tOFF = 18ns). A 12? maximum RON flatness ensures signal fidelity, while channel-to-channel mismatch is guaranteed to be less than 2.5?. The 3mm x 3mm Quad NoLead Flatpack (QFN) package alleviates board space limitations, making this newest line of low-voltage switches an ideal solution. The ISL43142 are quad single-pole/single-throw (SPST) devices.The ISL43142 has two NO and two NC switches and can be used as a dual SPDT, or a dual 2:1 multiplexer
