Low ON Resistance Wideband/Video
Quad 2-Channel MUX/DEMUX
Product Description:
Pericom Semiconductor's PI5V series of mixed signal video
circuits are produced in the Company's advanced CMOS
low-power technology, achieving industry leading perfor-
mance.
The PI5V330 is a true bidirectional Quad 2-channel
multiplexer/demultiplexer that is recommended for both
RGB and 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 exception-
ally 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 PI5V330 offers a high-performance, low-cost solution
to switch between video sources. The application section
describes the PI5V330 replacing the HC4053 multiplier and
buffer/amplifier.
