Description
The PI5C3383 is a 5-bit, 4-port bus switch with exchange
designed with a low On-Resistance allowing inputs to be
connected directly to outputs. The switch creates no additional
propagational delay or additional ground bounce noise. The
switch is turned ON by the Bus Enable (BE) input signal, and the
Bus Exchange (BX) input signal offers nibble swapping of the
AB and CD pairs of signals. This exchange configuration allows
byte swapping of buses in systems. It can also be used as a quad
2-to-1 multiplexer and to create low delay barrel shifters, etc.
