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 4Ω max

on-resistance (R

), 0.4Ω max R

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 (t

) and turn-off

OFF

) times of 18ns and 6ns, respectively, and is avail-

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.

3V/5V, 4Ω, Wideband Quad 2:1 Analog Multiplexer Low-Voltage Operation The MAX4674 operates from a single supply between +1.8V and +5.5V. At room temperature, it actually “works” with a single supply near or below +1.7V; as supply voltage decreases, however, switch on-resistance becomes very high. Overvoltage Protection Proper power-supply sequencing is recommended for all CMOS devices.
