PI3USB14
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).
