00 Jan 31, 2006 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.
