IDTQS3257 - HIGH-SPEED CMOS QUICKSWITCH QUAD 2:1 MUX/DEMUX
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
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 con
