The ADG442 is a monolithic CMOS device comprising four independently selectable switches. It is designed on an enhanced LC²MOS process which provides low power dissipation yet gives high switching speed and low on resistance.

The ADG442 switches are turned on with a logic high on the appropriate control input. Each switch conducts equally well in both directions when ON and each has an input signal range that extends to the supplies. All switches exhibit break-before-make switching action for use in multiplexer applications. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.
