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
− 2.5Ω bidirectional 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
APPLICATIONS
− 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
DESCRIPTION:
The QS32XR862 provides two sets of ten high-speed CMOS, TTL-
compatible, active high, low resistance bus switches. The very low ON
resistance (2.5Ω) 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.
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.
