ISL43240IA-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43240IA-T is a quad single-pole double-throw (SPDT) analog switch IC manufactured by Renesas Electronics. It features four independent channels with a maximum on-resistance of 25 Ohms and supports dual supply voltages ranging from ±2 V to ±6 V, or a single supply up to 12 V. The device operates within an industrial temperature range of -40°C to +85°C and is housed in an SSOP-20 package. Key electrical specifications include a maximum operating time of 65 ns, a maximum idle time of 50 ns, and a maximum power supply current of 1 µA.
