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
