Dual Monostable Multivibrators (with Schmitt Trigger Input)

REJ03D0591–0200

(Previous ADE-205-468)

Rev.2.00

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:

t_W= 0.7·(Rext)·(Cext)
