General Description

The MAX4674 is a low-voltage CMOS analog switch con-

taining four 2:1 multiplexers/demultiplexer. When pow-

ered from a single +5V supply, it features a low 4

Ω max

channels, and 0.8

Ω RON flatness over the entire signal

range. Off-leakage current is only 0.5nA max at +25

°C.

able in QFN, QSOP, TSSOP, and SO packages.

This low-voltage multiplexer operates with a +1.8V to

+5.5V single supply. All digital inputs have +0.8V and

+2.4V logic thresholds, ensuring TTL/CMOS-logic com-

patibility with +5V operation.
