QUAD 2:1 MUX/DEMUX

FEATURES:

DESCRIPTION:

• Enhanced N channel FET with no inherent diode to Vcc

• 5Ω bidirectional switches connect inputs to outputs

• Pin compatible with the 74F257, 74FCT257, and 74FCT257T

• Zero propagation delay, zero ground bounce

• Undershoot clamp diodes on all switch and control inputs

• TTL-compatible control inputs

The QS3257 is a high-speed CMOS LVTTL-compatible Quad 2:1

multiplexer/demultiplexer.TheQS3257isafunctionandpinoutcompatible

QuickSwitchversionofthe74F257, 74FCT257, andthe74ALS/AS/LS257

Quad2:1multiplexers. ThelowONresistanceoftheQS3257allowsinputs

to be connected to outputs without adding propagation delay and without

generating additional ground bounce noise.

• Available in QSOP and S1 packages

Mux/Demux devices provide an order of magnitude faster speed than

equivalent logic devices.

The QS3257 is characterized for operation at -40°C to +85°C.

APPLICATIONS:

• Logic replacement

• Video, audio, graphics switching, muxing

• Hot-swapping, hot-docking

• Voltage translation (5V to 3.3V)

• Bus funneling
