ISL43L122IR

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L122IR is a precision, bidirectional analog switch configured as a dual 2-to-1 multiplexer/demultiplexer. Designed for single-supply operation within the +1.6V to +3.6V range, it features an extremely low on-resistance of 0.5Ω at +3.0V and 0.62Ω at +1.8V. The device supports rail-to-rail analog signal handling with minimal off-leakage current, ensuring high signal integrity in sensitive applications. It operates reliably across an extended temperature range from -40°C to +85°C and is housed in a compact 16-lead TSSOP or QFN package.
