General Description

The MAX4741/MAX4742/MAX4743 are low on-resis-

tance, low-voltage, dual single-pole/single-throw (SPST)

analog switches that operate from a single +1.6V to

+3.6V supply. These devices have fast switching

quiescent power. The MAX4743 has break-before-

make switching.

When powered from a +3V supply, the MAX4741/

MAX4742/MAX4743 feature low 0.8

Ω (max) on-resis-

0.18

CMOS compatible when using a single +3V supply.

The MAX4741 has two normally open (NO) switches,

the MAX4742 has two normally closed (NC) switches,

and the MAX4743 has one NO switch and one NC

switch. The MAX4741/MAX4742/MAX4743 are available

in 8-pin SOT23 and 8-pin µMAX packages.
