General Description
The MAX4781/MAX4782/MAX4783 are high-speed,
low-voltage, low on-resistance, CMOS analog multiplex-
ers/switches configured as an 8-channel multiplexer
(MAX4781), two 4-channel multiplexers (MAX4782),
and three single-pole/double-throw (SPDT) switches
(MAX4783).
These devices operate with a +1.6V to +3.6V single
supply. When powered from a +3V supply, MAX4781/
MAX4782/MAX4783 feature a 0.7Ω on-resistance
(R
ON
), with 0.3Ω R
ON
matching between channels, and
0.1Ω R
ON
flatness. These devices handle rail-to-rail
analog signals while consuming less than 3µW of qui-
escent power. They are available in space-saving 16-
pin thin QFN (3mm x 3mm) and TSSOP packages.

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.
