The MAX4674 is a low-voltage CMOS analog switch containing four 2:1 multiplexers/demultiplexer. When powered from a single +5V supply, it features a low 4Ω max on-resistance (RON), 0.4Ω max RON matching between channels, and 0.8Ω RON flatness over the entire signal range. Off-leakage current is only 0.5nA max at +25°C.

The MAX4674 features fast turn-on (tON) and turn-off (tOFF) times of 18ns and 6ns, respectively, and is available 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 compatibility with +5V operation.
