74HC221 - Dual non-retriggerable monostable multivibrator

Description

The 74HC/HCT221 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL).

They are specified in compliance with JEDEC standard no.

7A.

Features

  • Pulse width variance is typically less than ± 5%.
  • Pin-out identical to “123”.
  • Overriding reset terminates output pulse.
  • nB inputs have hysteresis for improved noise immunity.
  • Output capability: standard (except for nREXT/CEXT).
  • ICC category: MSI.
