Dual Monostable Multivibrators (with Schmitt Trigger Input)

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 inpt that when taken low resets the one shot. The

HD74HC221 can be triggered on the positive transition of teh 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:

t_W= 0.7·(Rext)·(Cext)
