Description
Each multivibrator features both a negative, A, and a positive, B, transition triggered input, either of which can be used as an inhibit. Also included is a clear input that when taken low resets the one shot. The HD74HC221 can be triggered on the positive transition of the clear while A is held low and B is held high. This device is a non-retriggerable, and therefore cannot be retriggered until the output pulse times out. The output pulse equation is simply: tW = 0.7·(Rext)·(Cext)
