Part Number	74221
Manufacturer	NXP
Title	Dual non-retriggerable monostable multivibrator
Description	The 74HC/HCT221 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). 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 inpu.
Features	• Pulse width variance is typically less than ± 5% • Pin-out identical to “123” • Overriding reset terminates output pulse • nB inputs have hysteresis for improved noise immunity • Output capability: standard (except for nREXT/CEXT) • ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT221 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specif.

Title	Dual Non-Retriggerable Monostable Multivibrator
Description	The MM74HC221A high speed monostable multivibrators (one shots) utilize advanced silicon-gate CMOS technology. They feature speeds comparable to low power Schottky TTL circuitry while retaining the low power and high noise immunity characteristic of CMOS circuits. Each multivibrator features both a .
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 MM74HC221A can be triggered on the positive transition of the clear while A is held LOW and B is held HIGH. The MM74HC221A is a non-retriggerable, and therefore cannot be retriggered until the output pulse ti.
