74HC221 Description

Short technical summary and product information.

The 74HC221 is a high-speed Si-gate CMOS dual non-retriggerable monostable multivibrator manufactured by Harris Semiconductor. It offers pin compatibility with Low Power Schottky TTL (LSTTL) devices, making it suitable for integration into existing designs.

 

This component is specified in compliance with JEDEC standards. Its design as a monostable multivibrator allows it to generate a single output pulse of a defined duration in response to a trigger input. The 'dual' designation indicates it contains two independent multivibrator circuits within a single package.

 

While specific electrical characteristics such as operating voltage and propagation delay are not detailed here, the 74HC/HCT221 series is known for its high-speed performance. The device is suitable for various timing and pulse generation applications in digital logic circuits.
