0.8Ω, Low-Voltage, 4-Channel Analog Multiplexer
General Description
The MAX4734 is a low on-resistance, low-voltage, 4-
channel CMOS analog multiplexer that operates from a
single 1.6V to 3.6V supply. This device has fast switch-
ing speeds (tON= 25ns, tOFF= 20ns max), handles
rail-to-rail analog signals, and consumes less than 4µW
of quiescent power. The MAX4734 has break-before-
make switching.
When powered from a 3V supply, the MAX4734 fea-
tures low 0.8Ω(max) on-resistance (RON), with 0.2Ω
(max) RONmatching and 0.1ΩRONflatness. The digital
logic input is 1.8V CMOS compatible when using a sin-
gle 3V supply.
The MAX4734 is available in space-saving 12-pin thin
QFN (3mm x 3mm) and 10-pin µMAX packages.

ELECTRICAL CHARACTERISTICS—Single 3V Supply
(V+ = 2.7V to 3.6V, VIH= 1.4V, VIL= 0.5V, TA= TMINto TMAX, unless otherwise specified. Typical values are at V+ = 3.0V,= +25°C.) (Notes 2, 3)
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.
Note 1:Signals on COM or NO_ exceeding V+ or GND are clamped by internal diodes. Limit forward current to maximum current rating.
