IDTQS34XR245
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
• QS34XR245Q3 is a 32-bit version of QS3R245
• Flow-through pinout for easy layout
• Undershoot clamp diodes on all switch and control inputs
• TTL-compatible control inputs
• Available in 80-pin Millipaq package
APPLICATIONS:
• Low resistance applications
• Hot-swapping, hot-docking (low resistance for PCI and
Compact PCI applications)
• Bus switching, isolation
• Logic replacement (data processing)
• Capacitance reduction and isolation

DESCRIPTION:
The QS34XR245 is a member of the MultiWidthTM family of QuickSwitch
devices and provides a set of 32 high-speed low resistance CMOS compatible
bus switches in a flow-through pin out.
This device is available in the MillipaQ package, the worlds first small outline
32-bit solution. The low on-resistance of the QS34XR245 allows inputs to be
connected to outputs without adding propagation delay and without generating
additional ground bounce noise. When Output Enable (OEx) is low, the switches
are turned on, connecting bus A to bus B. When OEx is high, the switches are
turned off.
The QS34XR245 is ideally suited for 32/64 bit applications where board
space is at a premium. The low resistance of QS34XR245 makes it ideal for PCI
hot docking application.
QuickSwitch devices provide an order of magnitude faster speed than
conventional logic devices.
