MULTIWIDTH™ BUS SWITCHES
IDTQS34X245
FEATURES:
• Enhanced N channel FET with no inherent diode to Vcc
• Bidirectional switches connect inputs to outputs
• Zero propagation delay, zero ground bounce
• QS34X245 is 32-bit version of QS3245
• 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:
• Hot-swapping, hot-docking
• Voltage translation (5V to 3.3V)
• Bus switching and isolation
• Power conservation
• Logic replacement (data processing)
• Capacitance isolation
• Clock gating
DESCRIPTION:
The QS34X245 is a member of the MultiWidthTM family of QuickSwitch
devices and provides a set of 32 high-speed CMOS compatible bus switches
in a flow-through pinout. This device is available in the MilliPaQ package,
the world's first small outline 32-bit solution. The low ON-resistance of the
QS34X245 allows inputs to be connected to outputs without adding propa-
gation delay and without generating additional ground bounce noise. When
Output Enable (OEn) is low, the switches are turned on, connecting bus A
to bus B. When OEn is high, the switches are turned off. This device is ideally
suited for 32/64 bit applications where board space is at a premium.
QuickSwitch devices provide speeds an order of magnitude faster than
conventional logic devices.
The QS34X245 is characterized for operation at -40°C to +85°C.
