MM54C221/MM74C221 Dual Monostable Multivibrator  
General Description  
The MM54C221/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.  
Pulse stability will be limited by the accuracy of external  
timing components. The pulse width is approximately de-
