IDTQS3257
FEATURES:
• 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
• Available in SOIC, QSOP, and S1 packages
DESCRIPTION:
The QS3257 is a high-speed CMOS LVTTL-compatible Quad 2:1
multiplexer/demultiplexer. The QS3257 is a function and pinout compatible
QuickSwitch version of the 74F257, 74FCT257, and the 74ALS/AS/LS257
Quad 2:1 multiplexers. The low ON resistance of the QS3257 allows inputs
to be connected to outputs without adding propagation delay and without
generating additional ground bounce noise.
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
