ISL43L121IU

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L121IU is a dual single-pole double-throw (SPST) normally-closed analog switch manufactured by Renesas Electronics Corporation. It operates from a single supply voltage ranging from 1.65V to 3.6V and is housed in an 8-MSOP package. The device features a maximum on-resistance of 250 milliohms with a channel-to-channel matching of 5 milliohms. Switching times are limited to 25ns for both turn-on and turn-off. Key electrical parameters include a charge injection of -125pC, off-state leakage current of 3nA maximum, and crosstalk of -94dB at 100kHz. It supports an operating temperature range of -40°C to 85°C.
