ISL43240IR

Analog Switches, Multiplexers, Demultiplexers Overview

The Renesas ISL43240IR is a CMOS, precision, quad single-pole/double-throw (SPDT) analog switch designed for operation from a single +2V to +12V supply or dual ±2V to ±6V supplies. It features four independently controlled SPDT switches with an on-resistance of 18Ω and channel-to-channel matching under 1Ω. The device exhibits low charge injection of 5pC maximum, power consumption below 5µW, and off-leakage current of 2.5nA at +85°C. Switching times are specified as 52ns for turn-on and 40ns for turn-off. It includes guaranteed break-before-make timing and offers 2000V ESD protection per method 3015.7.
