| Overview | 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 i. 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 an. |
