FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3R862 provides a set of ten high-speed CMOS TTL-compatible
bus switches. The very low ON resistance (2.5Ω) of the QS3R862 allows
inputs to be connected to outputs without adding propagation delay and
without generating additional ground bounce noise. The switches are
controlled by active Low Enable (BE) and active High Enable (BE) controls.
The QS3R862 with 2.5Ω RON resistance is ideal for switching digital
buses as well as for hot-plugging, hot-swapping, and hot-docking applica-
tions. The low RON resistance of the QS3R862 makes it ideal for PCI,
Compact PCI, and VME hot-plugging applications.
The QS3R862 is characterized for operation at -40°C to +85°C.
