CD54HC123 - High-Speed CMOS Logic Dual Retriggerable Monostable Multivibrators

Datasheet Summary

Description

The ’HC123, ’HCT123, CD74HC423 and CD74HCT423 are dual monostable multivibrators with resets.

They are all retriggerable and differ only in that the 123 types can be triggered by a negative to positive reset pulse; whereas the 423 types do not have this feature.

Features

  • Overriding Reset Terminates Output Pulse.
  • Triggering From the Leading or Trailing Edge.
  • Q and Q Buffered Outputs.
  • Separate Resets.
  • Wide Range of Output-Pulse Widths.
  • Schmitt Trigger on Both A and B Inputs.
  • Fanout (Over Temperature Range) - Standard Outputs.
  • 10 LSTTL Loads - Bus Driver Outputs.
  • . . . 15 LSTTL Loads.
  • Wide Operating Temperature Range . . . -55oC to 125oC.
  • Bal.
