FST3383
10-Bit Low Power Bus-Exchange Switch
General Description
The FST3383 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
provides nibble swapping of the AB and CD pairs of sig-
nals. 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.
