SN54AHC123A - DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATORS

General Description

The ’AHC123A devices are dual retriggerable monostable multivibrators designed for 2-V to 5.5-V VCC operation.

These edge-triggered multivibrators feature output pulse-duration control by three methods.

In the first method, the A input is low, and the B input goes high.
