Description

Pericom Semiconductor’s PI3V312 is a 4-port, 2:1 Multiplexer/

Demultiplexer with 3-state outputs. The switch introduces no ad-

ditional ground bounce noise or propagation delay.

Low On-Resistance and High bandwidth make it ideal for video

and other applications. Also this device has exceptionally low

crosstalk and off-isolation, which is far greater than most analog

switches offered today. A single 3.3V supply is all that is required

for operation.

The PI3V312 offers a high-performance (500MHz), low-cost solu-

tion to switch between video signals that have high bandwidth.
