PI5C33X257
12 Channel, 2:1 Mux/DeMux Bus Switch
PI5C33X257
12-Channel, 2:1 Mux/DeMux Bus Switch
Description
The PI5C33X257 is a 12-channel, 2:1 multiplexer/demultiplexer
with three-state outputs. Inputs can be connected to outputs with
low on resistance (5-ohm) with no additional ground bounce noise
or propagation delay.
