QUICKSWITCH

8-BIT BUS SWITCH

FEATURES:

DESCRIPTION:

• Enhanced N channel FET with no inherent diode to Vcc

• 5Ω bidirectional switches connect inputs to outputs

• Pin compatible with 74F244, 74FCT244, and 74FCT244T

• Zero propagation delay, zero ground bounce

TheQS3244providesasetofeighthigh-speedCMOSTTL-compatible

bus switches in a pinout compatible with 74FCT244, 74F244, 74ALS/AS/

LS244 8-bit drivers. The low ON resistance (5Ω) of the 3244 allows inputs

to be connected to outputs without adding propagation delay and without

generating additional ground bounce noise. The two enable (xG) signals

turn the switches on similar to the xG signals of the 74’244.

• Undershoot clamp diodes on all switch and control inputs

• Available in QSOP, SOIC, and TSSOP packages

QuickSwitch devices provide an order of magnitude faster speed than

conventionallogicdevices.

The QS3244 is characterized for operation at -40°C to +85°C.

APPLICATIONS:

• Hot-swapping, hot-docking

• Voltage translation (5V to 3.3V)

• Power conservation

• Capacitance reduction and isolation

• Logic replacement (data processing)

• Clock gating

• Bus switching and isolation
