QUICKSWITCH 32-BIT

MULTIWIDTH™ BUS SWITCHES

DESCRIPTION:

FEATURES:

The QS34X245 is a member of the MultiWidth^TMfamily of QuickSwitch

devicesandprovidesasetof32high-speedCMOScompatiblebusswitches

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

QS34X245allowsinputstobeconnectedtooutputswithoutaddingpropa-

gationdelayandwithoutgeneratingadditionalgroundbouncenoise. When

Output Enable (OEn) is low, the switches are turned on, connecting bus A

tobusB. WhenOEnishigh,theswitchesareturnedoff.Thisdeviceisideally

suited for 32/64 bit applications where board space is at a premium.

QuickSwitch devices provide speeds an order of magnitude faster than

conventionallogicdevices.

• 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

The QS34X245 is characterized for operation at -40°C to +85°C.

• Logic replacement (data processing)

• Capacitance isolation

• Clock gating
