74VHC221A Product details

Description

The VHC221A is an advanced high speed CMOS Monostable Multivibrator fabricated with silicon gate CMOS technology..

Features

both a negative, A, and a positive, B, transition triggered input, either of which can be used as an inhibit input. Also included is a clear input that when taken LOW resets the one-shot. The VHC221A can be triggered on the positive transition of the clear while A is held LOW and B is held HIGH. The VHC221A is non-retriggerable, and therefore cannot be retriggered until the output pulse times out. The output pulse width is determined by the equation: PW = (Rx)(Cx); where PW is in seconds, R is i.
