General Description
The MAX4751/MAX4752/MAX4753 are low on-resistance,
low-voltage, quad, single-pole/single-throw (SPST) analog
switches that operate from a single +1.6V to +3.6V sup-
ply. These devices have fast switching speeds (t
ON
=
30ns, t
OFF
= 25ns), handle rail-to-rail analog signals, and
consume less than 1µW of quiescent power. The
MAX4753 has break-before-make switching.
When powered from a +3V supply, the MAX4751/
MAX4752/MAX4753 feature low 0.9Ω (max) on-resis-
tance (R
ON
), with 0.12Ω (max) R
ON
matching and 0.1Ω
(max) R
ON
flatness. The digital input is 1.8V CMOS
compatible when using a single +3V supply.
The MAX4751 has four normally open (NO) switches,
the MAX4752 has four normally closed (NC) switches,
and the MAX4753 has two NO and two NC switches.
The MAX4751/MAX4752/MAX4753 are available in
3mm
3mm, 16-pin QFN and 14-pin TSSOP packages.
