Low Voltage, High Bandwidth, USB 2.0,

4:1 Mux/DeMux with Single Enable

Description

The PI3USB14 is a 2-channel, 4:1 Multiplexer/Demultiplexer with

3-state outputs. The switch introduces no additional ground bounce

noise or propagation delay.

The PI3USB14 device is very useful in switching USB 2.0 signals

and others that have high bandwidth (300MHz).
