54LVX3383
10-Bit Low Power Bus-Exchange Switch
General Description
The 54LVX3383 provides two sets of high-speed CMOS
TTL-compatible bus switches. The low on resistance of the
switch allowsinputs to be connected to outputs without adding propagation delay or generating additional ground
bounce noise. The device operates as a 10-bit bus switch or
a 5-bit bus exchanger. The bus exchange (BX) signal provides 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. The bus enable (BE )
signal turns the switches on.
