74HC221 Description

Short technical summary and product information.

The 74HC221 is a high-speed Si-gate CMOS dual non-retriggerable monostable multivibrator manufactured by Texas Instruments. It is designed to be pin compatible with Low Power Schottky TTL (LSTTL) devices, offering a bridge between older and newer logic families.

 

This component is specified in compliance with JEDEC standards. Its primary function is to provide a single stable output pulse of a predetermined duration in response to a trigger input. The dual nature of the device allows for two independent monostable circuits within a single package.

 

Key specifications include its RoHS3 compliance and Moisture Sensitivity Level (MSL) of 1, indicating it is suitable for a wide range of manufacturing environments. The REACH status is unaffected, further simplifying its integration into global supply chains.

 

Designed for general-purpose timing and pulse generation applications, the 74HC221 is a reliable choice for engineers seeking a robust monostable multivibrator solution. Its CMOS technology ensures low power consumption while maintaining high-speed performance.
