Description
Pericom Semiconductor鈥檚 PI3CH series of switch circuits are
produced using the Company鈥檚 advanced sub-micron CMOS
technology, achieving industry leading performance.
The PI3CH281 is a 2-channel, 4:1 Multiplexer/Demultiplexer with
3-state outputs. The switch introduces no additional ground bounce
noise or propagation delay.
The PI3CH281 device is very useful in switching signals that have
high bandwidth (300MHz).
