IDTQS34X383 HIGH-SPEED 32-BIT BUS EXCHANGE SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS HIGH-SPEED 32-BIT BUS EXCHANGE SWITCH IN MILLIPAQ™ FEATURES: IDTQS34X383 5Ω switches connect inputs to outputs Zero propagation delay Direct bus connect Live insertion capability Low power CMOS proprietary technology Bus exchange allows nibble swap TTL-compatible control inputs Available in 80-pin Millipaq package The QS34X383 provides four sets of eight high-speed CMOS TTLcompatible 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. The QS34X383 is characterized for operation at -40°C to +85°C.
