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 allows inputs to be connected to outputs without add-
ing 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.
Features
n 5switch connection between two ports
n Minimal propagation delay through the switch
n Ultra low power with 0.2 µA typical ICC
n Zero ground bounce in flow-through mode
n Control inputs compatible with TTL level
n Available in CDIP and Flatpack packages
n Standard Microcircuit Drawing (SMD) 5962-9950601
