QUICKSWITCH 8-BIT LOW

RESISTANCE BUS SWITCH

DESCRIPTION:

FEATURES:

TheQS3R245providesasetofeighthigh-speedCMOSTTL-compatible

bus switches in a pinout compatible with 74FCT245, 74F245, 74ALS/AS/

LS245 8-bit transceivers. The low ON resistance of the QS3R245 allows

inputs to be connected to outputs without adding propagation delay and

withoutgeneratingadditionalgroundbouncenoise.TheOutputEnable(OE)

signal turns the switches on similar to the OEsignal of the 74’245. The low

ONresistanceofQS3R245makesitidealforPCIhotdockingapplications.

QuickSwitch devices provide an order of magnitude faster speed than

conventionallogicdevices.

• Enhanced N channel FET with no inherent diode to Vcc

• 5Ω bidirectional switches connect inputs to outputs

• Pin compatible with the 74F245, 74FCT245, and 74FCT245T

• Zero propagation delay, zero ground bounce

• Undershoot clamp diodes on all switch and control inputs

• TTL-compatible control inputs

• Available in SOIC and QSOP packages

The QS3R245 is characterized for operation at -40°C to +85°C.

APPLICATIONS:

• Hot-swapping and hot-docking (low resistance for PCI and

Compact PCI applications)

• Bus switching and isolation

• Voltage translation (5V to 3.3V)

• Capacitance reduction and isolation

• Power conservation

• Logic replacement (data processing)

• Clock gating
