74C221 Datasheet Dual Monostable Multivibrator

Manufacturer: Fairchild (now onsemi)

Overview: MM74C221 Dual Monostable Multivibrator November 1987 Revised January 1999 MM74C221 Dual Monostable.

General Description

The MM74C221 dual monostable multivibrator is a monolithic plementary MOS integrated circuit.

Each multivibrator

Key Features

  • a negative-transition-triggered input and a positive-transition-triggered input, either of which can be used as an inhibit input, and a clear input. Once fired, the output pulses are independent of further transitions of the A and B inputs and are a function of the external timing components CEXT and REXT. The pulse width is stable over a wide range of temperature and VCC. Pulse stability will be limited by the accuracy of external timing components. The pulse width is approximately defined by t.
