Overview
The MAX4581/MAX4582/MAX4583 construction is typi-
cal of most CMOS analog switches. They have three
supply pins: V
CC
, V
EE
, and GND. V
CC
and V
EE
are used
to drive the internal CMOS switches and set the limits of
the analog voltage on any switch. Reverse ESD-
protection diodes are internally connected between
each analog-signal pin and both V
CC
and V
EE
. If any
analog signal exceeds V
CC
or V
EE
, one of these diodes
Pin Description
Note: Input and output pins are identical and interchangeable. Any may be considered an input or output; signals pass equally well
in both directions.
