General 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.

Key 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 QSOP and S1 packages.
