GENERAL DESCRIPTION
The ADG1334 is a monolithic CMOS device comprising
four independently selectable SPDT switches designed on a
CMOS process.
When the switches are on, each switch conducts equally well
in both directions and has an input signal range that extends to
the power supplies. In the off condition, signal levels up to the
supplies are blocked. All switches exhibit break-before-make
switching action for use in multiplexer applications. Inherent in
the design is the low charge injection for minimum transients
when switching the digital inputs.
Fast switching speed coupled with high signal bandwidth makes
the part suitable for video signal switching. CMOS construction
ensures ultra ow power dissipation, making the part ideally
suited for portable and battery-powered instruments.
