MM74HC221AM Description

Short technical summary and product information.

The MM74HC221AM from ON Semiconductor is a high-speed dual non-retriggerable monostable multivibrator utilizing advanced silicon-gate CMOS technology. It offers speeds comparable to low power Schottky TTL while retaining the noise immunity characteristic of CMOS circuits.

 

This device features a wide power supply range of 2V to 6V and a typical propagation delay of 22 ns. The output pulse width is determined by an external resistor and capacitor (T = RC). It includes both negative (A) and positive (B) transition triggered inputs, which can also function as inhibit inputs. A clear input is also provided for resetting the one-shot.

 

The MM74HC221AM is supplied in a 16-SOIC package suitable for surface mounting. It operates over a temperature range of -40°C to 85°C. The low quiescent current and low input current make it suitable for various digital logic applications where precise timing and low power consumption are required.
