Overview

MM74HC221A Dual Non-Retriggerable Monostable Multivibrator September 1983 Revised February 1999 MM74HC221A Dual Non-Retriggerable Monostable Multivibrator General Description The MM74HC221A high speed monostable multivibrators (one shots) utilize advanced silicon-gate CMOS technology.
They feature speeds comparable to low power Schottky TTL circuitry while retaining the low power and high noise immunity characteristic of CMOS circuits.
Each multivibrator features both a negative, A, and a positive, B, transition triggered input, either of which can be used as an inhibit input.
Also included is a clear input that when taken low resets the one shot.
The MM74HC221A can be triggered on the positive transition of the clear while A is held LOW and B is held HIGH.
The MM74HC221A is a non-retriggerable, and therefore cannot be retriggered until the output pulse times out.
Pulse width stability over a wide range of temperature and supply is achieved using linear CMOS techniques.
The output pu...
