The QS32X384 provides a set of twenty high-speed CMOS TTLcompatible bus switches. The low ON resistance of the QS32X384 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The Bus Enable (BE) signals turn the switches on. Four Bus Enable signals are provided, one for each of five bits of the 20-bit bus. The ‘384 family of QuickSwitch products is ideal for switching wide digital buses, as well as hotplug buffering, and 5V to 3V conversion. The QS32X384 is characterized for operation at -40°C to +85°C.
