The QS32XL384 provides a set of twenty high-speed CMOS TTLcompatible bus switches. The low ON resistance of the QS32XL384 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 hot-docking, 5V to 3V conversion and capacitance isolation for power conservation. The QS32XL384 is characterized for operation at -40C to +85C.
