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.
