CD54HC251F - 8-Input Multiplexer

Download the CD54HC251F datasheet PDF (CD54HC251 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for 8-input multiplexer.

Description

The ’HC251 and ’HCT251 are 8-channel digital multiplexers with three-state outputs, fabricated with high-speed silicongate CMOS technology.

Together with the low power consumption of standard CMOS integrated circuits, they possess the ability to drive 10 LSTTL loads.

Features

  • Selects one of eight binary data inputs.
  • Three-state output capability.
  • True and complement outputs.
  • Typical (data to output) propagation delay of 14 ns at VCC = 5 V, CL = 15 pF, TA = 25 ℃.
  • Fanout (over temperature range).
  • Standard outputs : 10 LSTTL loads.
  • Bus driver outputs : 15 LSTTL loads.
  • Wide operating temperature range :.
  • 55 ℃ to 125 ℃.
  • Balanced propagation delay and transition times.
  • Signi.
