ISL43140IVZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43140IVZ is a quad single-pole single-throw (SPST) analog switch IC manufactured by Renesas Electronics. It operates on a single supply voltage ranging from 2 V to 12 V or dual supplies of ±1 V to ±6 V. The device features a maximum on-resistance of 65 Ohms and supports a continuous DC switch current of 10 mA. Key timing specifications include a maximum turn-on time of 70 ns and a maximum turn-off time of 50 ns. It functions within an industrial temperature range of -40°C to +85°C and is housed in a 16-pin TSSOP surface-mount package.
