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.
