ISL43140 Low-Voltage, Single and Dual Supply, High Performance, Quad SPST, Analog Switches

The Intersil ISL43140,ISL43141,ISL43142 devices are 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 12Ω maximum RON flatness ensures signal fidelity, while channel-to-channel mismatch is guaranteed to be less than 2.5Ω. The 3mm x 3mm Quad No- Lead Flatpack (QFN) package alleviates board space limitations, making this newest line of low-voltage switches an ideal solution.

The ISL43140/ISL43141/ISL43142 are quad single-pole/ single-throw (SPST) devices. The ISL43140 has four normally closed (NC) switches; the ISL43141 has four normally open (NO) switches; the ISL43142 has two NO and two NC switches and can be used as a dual SPDT, or a dual 2:1 multiplexer.
