Fast, Low-Voltage, 4鈩?
4-Channel CMOS Analog Multiplexer
General Description
The MAX4634 fast, low-voltage, 4-channel CMOS ana-
log multiplexer features 4鈩?(max) on-resistance (R
ON
).
It offers R
ON
matching between switches to 0.3鈩?(max)
and R
ON
flatness of 1鈩?(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掳C.
The MAX4634 features fast turn-on (t
ON
) and turn-off
(t
OFF
) times of 18ns and 11ns, respectively. All this
comes in the tiny 10-pin 碌MAX and 10-pin, 3mm x 3mm,
thin QFN 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.
