The QS3383 provides ten high-speed CMOS TTL-compatible bus switches. The low ON-resistance of the QS3383 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. Bus exchange configuration allows byte swapping of buses in systems. It can also be used as a 5-wide 2-to-1 multiplexer and to create low-delay barrel shifters, etc. The QS3383 operates at -40 °C to +85 °C.

The QS33X257 is a high-speed CMOS TTL-compatible 24:12 multiplexer/demultiplexer. The QS33X257 is functionally compatible to three of the QuickSwitch versions of the 74F257, 74FCT257, and the 74ALS/AS/LS257 quad 2:1 multiplexers. The low ON-resistance of the QS33X257 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The QS33X257 operates at -40 °C to +85 °C.

The QS34X2245 provides a set of 32 high-speed CMOS-compatible bus switches in a flow-through pinout. The low ON-resistance of the QS34X2245 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. Internal 25Ω resistors reduce reflection noise in high-speed applications. This device is ideally suited for 32/64-bit applications where board space is at a premium. The QS34X2245 operates at -40 °C to +85 °C.

The QS34X383 provides four sets of eight high-speed CMOS TTL-compatible bus switches. The low ON resistance (5 ohm) of the QS34X383 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The Bus 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 operates at -40C to +85C.

The QS34XVH2245 high-bandwidth, 32-bit bus switch with 25Ω resistance and 1.35ns propagation delay is ideal for line matching and low noise environments. The switches can be turned ON under the control of individual LVTTL-compatible Output Enable (OEx) signals for bidirectional data flow with no added delay or ground bounce. The combination of small propagation delay, high OFF impedance, and overvoltage tolerance makes the QS34XVH2245 ideal for high-performance communications applications. The QS34XVH2245 operates from -40 °C to +85 °C.
