74HCT221 Dual non-retriggerable monostable multivibrator with reset Rev. 3 — 26 October 2016 Product data sheet 1. General description The 74HCT221 is a dual non-retriggerable monostable multivibrator. Each multivibrator features edge-triggered inputs (nA and nB), either of which can be used as an enable input. Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input pulse. Schmitt-trigger input circuitry for the nB inputs allow j.

They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT221 are dual non-retriggerable monostable multivibrators. Each multivibrator features an active LOW-going edge input (nA) and an active HIGH-going edge input (nB), either of which can be used as an enable input. Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input pulse. Schmitt-trigger input circuitry for the nB inputs allow 74HC/HCT221 jitter-free triggering from inputs with slow transition rates, providing the circuit with excellent.
