Analog Switches, Multiplexers, Demultiplexers datasheet and documents for ISL43L740IR

ISL43L740IR

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L740IR is a precision, bidirectional analog switch configured as a dual 4-channel multiplexer/demultiplexer. It operates from a single supply voltage ranging from +1.6V to +3.6V. The device features an on-resistance of 0.5Ω at a +3.0V supply and 0.62Ω at a +1.8V supply. Each switch supports rail-to-rail analog signal handling with low off-leakage current, specified as 4nA maximum at +25°C and 30nA maximum at +85°C when using a +3.3V supply. Digital inputs are compatible with 1.8V logic levels under a +3V supply condition.

Analog Switches, Multiplexers, Demultiplexers Feature Summary
