General Description
The MAX4704 low-voltage, 4-channel analog multiplex-
er operates from a single +1.8V to +5.5V supply. The
MAX4704 features break-before-make switching action
with a t
ON
= 60ns and t
OFF
= 20ns at +3V.
When powered from a +2.7V supply, the device has a
60
(max) on-resistance (R
ON
), with 3
(max) R
ON
matching and 5
max R
ON
flatness. The digital logic
inputs are 1.8V-logic compatible from a +2.7V to +3.3V
supply. The MAX4704 is available in both a space-sav-
ing 12-pin QFN (3mm x 3mm) package and a 10-pin
MAX package.

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 INH, ADD_, NO_, and COM exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current
to maximum current rating.
