11.14. PI5V330
11.14.1. General 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 performance.
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
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 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.
