3V/5V, 4Ω, Wideband Quad
2:1 Analog Multiplexer
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
ON
), 0.4Ω max R
ON
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
ON
) and turn-off
(t
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.

Note 1:
Signals on NO_, NC_, and COM_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to max-
imum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
