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
speeds (t
ON
= 24ns, t
OFF
= 16ns max), handle Rail-to-
Rail
analog signals, and consume less than 1μW of
quiescent power. The MAX4743 has break-before-
make switching.
When powered from a +3V supply, the MAX4741/
MAX4742/MAX4743 feature low 0.8
(max) on-resis-
tance (R
ON
), with 0.08
(max) R
ON
matching and
0.18
R
ON
flatness. The digital logic input is 1.8V
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.
