Description
Pericom Semiconductor’s PI5V331 is a true bi di rec tion al Dual
4-channel multiplexer/demultiplexer that is rec om mend ed for
both S-Video or composite video switching applications. e
switch can be driven from a current output RAMDAC or voltage
output composite video source.
Low On-resistance and wide bandwidth make it ideal for video
and other applications. Also this device has exceptionally high
current capability which is far greater than most analog switches
oered today. A single 5V supply is all that is required for opera-
tion.
e PI5V331 oers a high-performance, low-cost solution to
switch between video sources.
