__________Applications Information

Power-Supply Considerations

Overview

The MAX4581/MAX4582/MAX4583 construction is typi-

cal of most CMOS analog switches. They have three

supply pins: VCC, VEE, and GND. VCC and VEE 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 VCC and VEE. If any

analog signal exceeds VCC or VEE, one of these diodes
