MAX4734EGC+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4734EGC+ is a low on-resistance, low-voltage, 4-channel CMOS analog multiplexer operating from a single 1.6V to 3.6V supply. It features fast switching speeds with turn-on and turn-off times of 25ns and 20ns maximum at 3V. The device handles rail-to-rail analog signals and consumes less than 4μW of quiescent power. At a 3V supply, it offers a maximum on-resistance of 0.8Ω, 0.2Ω matching, and 0.1Ω flatness. It supports continuous current handling up to 150mA and utilizes break-before-make switching logic.
