IDTQS34X383 HIGH-SPEED 32-BIT BUS EXCHANGE SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH PRODUCTS IDTQS34X383 HIGH-SPEED 32-BIT BUS EXCHANGE SWITCH IN MILLIPAQ DESCRIPTION: FEATURES: 5 switches connect inputs to outputs The QS34X383 provides four sets of eight high-speed CMOS TTL- Zero propagation delay compatible bus switches. The low ON resistance (5) of the QS34X383 Direct bus connect allows inputs to be connected to outputs without adding propagation delay Live insertion capability and without generating additional ground bounce noise. The Bus Enable Low power CMOS proprietary technology (BEx) signals turn the switches on. The Bus Exchange (BXx) signals Bus exchange allows nibble swap provide nibble swap of the AB and CD pairs of signals. This exchange TTL-compatible control inputs configuration allows byte swapping of buses in systems. It can also be used Available in 80-pin Millipaq package as a 16-bit 2-to-1 multiplexer and to create low delay barrel shifters, etc. The QS34X383 is characterized for operation at -40C to +85C.
