MAX4634EUB

Fast, Low-Voltage, 4Ω, 4-Channel CMOS Analog Multiplexer

Maxim Integrated 

19-1717; Rev 3; 2/09

Fast, Low-Voltage, 4Ω,

4-Channel CMOS Analog Multiplexer

General Description

The MAX4634 fast, low-voltage, 4-channel CMOS ana-

log multiplexer features 4Ω (max) on-resistance (RON).

It offers RON matching between switches to 0.3Ω (max)

and RON flatness of 1Ω (max) over the specified signal

range. Each switch can handle V+ to GND analog sig-

nals. Off-leakage current is only 0.1nA (max) at +25°C.

The MAX4634 features fast turn-on (tON) and turn-off

(tOFF) times of 18ns and 11ns, respectively. All this

comes in the tiny 10-pin µMAX® and 10-pin, 3mm x

3mm, TDFN packages.

This low-voltage multiplexer operates from 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.
