ISL43L840IVZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L840IVZ-T is a dual-channel analog switch manufactured by Renesas Electronics Corporation, housed in a 16-TSSOP surface-mount package. It functions as two independent SP4T (Single Pole Four Throw) switches or a 4:1 multiplexer/demultiplexer circuit. The device operates on a single supply voltage ranging from 1.6V to 3.6V. Key electrical specifications include a maximum on-resistance of 750 milliohms and a channel-to-channel matching of 120 milliohms. It features low charge injection of -96pC, off-state leakage current of 4nA maximum, and a typical operating temperature range of -40°C to +85°C.
