DESCRIPTION:
compatible bus switches. The low ON resistance (5Ω) of the QS34X383
allows inputs to be connected to outputs without adding propagation delay
and without generating additional ground bounce noise. The Bus Enable
(BEx) signals turn the switches on. The Bus Exchange (BXx) signals
provide nibble swap 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 16-bit 2-to-1 multiplexer and to create low delay barrel shifters, etc.
