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. For conditions shown as Min. or Max., use the appropriate values specified under DC Electrical Characteristics.
2. Typical values are at VCC = 5.0V, TA = 25°C.
3. Per TLL driven input (VIN = 3.4V, control inputs only). A and B pins do not contribute to Icc.
4. This current applies to the control inputs only and represents the current required to switch internal capacitance at the specified frequency. The A
and B inputs generate no significant AC or DC currents as they transition. This parameter is guaranteed but not production tested.

NOTES:
1. Minimums are guaranteed but not production tested.
2. This parameter is guaranteed but not production tested.
3. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time
constant for the switch alone is of the order of 0.12ns for CL = 50pF. Since this time constant is much smaller than the rise and fall times of typical
driving signals, it adds very little propagation delay to the system. Propagation delay of the bus switch, when used in a system, is determined by the
driving circuit on the driving side of the switch and its interaction with the load on the driven side.
