General Description

The MAX4780/MAX4784 are low on-resistance, low-

voltage, quad 2:1 analog multiplexers that operate from

a single +1.6V to +4.2V supply. These devices have

rail-to-rail analog signals, and consume less than 1µW

of quiescent power.

When powered from a +2.7V supply, the MAX4780/

MAX4784 feature low 0.7

0.1

CMOS-logic compatible when using a single +3V supply.

The MAX4780/MAX4784 are available in 16-pin TSSOP

and 3mm x 3mm thin QFN packages.
