Product Description
Pericom Semiconductors PI5V series of mixed signal video
circuits are produced using the Companys advanced CMOS low
power technology achieving industry leading performance.
The PI5V331 is a true bidirectional Dual 4-channel multiplexer/
demultiplexer that is recommended for both S-Video or composite
video switching applications. The VideoSwitch 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
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.
