Overview
MM74C221 Dual Monostable Multivibrator November 1987 Revised January 1999 MM74C221 Dual Monostable Multivibrator General Description The MM74C221 dual monostable multivibrator is a monolithic complementary MOS integrated circuit.
Each multivibrator 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 timi...
