QUICKSWITCH® PRODUCTS
IDTQS32XR862
HIGH-SPEED CMOS 20-BIT LOW
RESISTANCE, ACTIVE HIGH BUS SWITCH
WITH FLOW-THROUGH PINOUT
FEATURES:
Enhanced N channel FET with no inherent diode to Vcc
2.5bidirectional switches connect inputs to outputs
Zero propagation delay, zero ground bounce
Undershoot clamp diodes on all switch and control pins
Active Low and High enable controls
Available in 48-pin QVSOP Package
DESCRIPTION:
The QS32XR862 provides two sets of ten high-speed CMOS, TTL-
compatible, active high, low resistance bus switches. The very low ON
resistance (2.5) of the QS32XR862 allows inputs to be connected to
outputs without adding propagation delay and without generating additional
ground bounce noise. The switches are controlled by independent active
Low Enable (BE) and active High Enable (BE) controls for each set.

Hot-swapping and hot-docking (low RON resistance for PCI and
Compact PCI applications)
Voltage translation (5V to 3.3V)
Power conservation
Capacitance reduction and isolation
Applications requiring Low resistance and active High enabling
Bus isolation
Clock gating
The QS32XR862 is ideal for switching digital buses as well as for hot plug
buffering and 5V to 3.3V conversion. The low ON resistance of the
QS32XR862 makes it ideal for PCI hot -docking applications.
The QS32XR862 is characterized for operation at -40°C to +85°C.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or
any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum
