HIGH-SPEED 32-BIT BUS EXCHANGE

SWITCH IN MILLIPAQ

™

DESCRIPTION:

The QS34X383 provides four sets of eight high-speed CMOS TTL-

compatible bus switches. The low ON resistance (5

Ω) 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.

The QS34X383 is characterized for operation at -40°C to +85°C.
