FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS32XL384 provides a set of twenty high-speed CMOS TTL-
compatible 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 -40°C to +85°C.
