74LVX3L383
10-Bit Low Power Bus-Exchange Switch
General Description
The LVX3L383 provides two sets of high-speed CMOS TTL-
compatible bus switches The low on resistance of the
switch allows inputs 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 pro-
vides 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
