Description
Pericom Semiconductor’s PI5V331 is a true bidirectional Dual 4-
channel multiplexer/demultiplexer that is recommended for both
S-Video or composite video switching applications. The 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 cur-
rent capability which is far greater than most analog switches offered
today. A single 5V supply is all that is required for operation.
The PI5V331 offers a high-performance, low-cost solution to
switch between video sources.
