Working Principles

CD74HCT123M96 operates as a monostable multivibrator, which means it generates a single pulse of a specific duration when triggered. The time period of the pulse is determined by external resistors and capacitors connected to the RCext, Rext, and Cext pins. Upon receiving a trigger signal at the A or B input, the internal flip-flop sets the time period based on the values of the external components. After the specified time period, the output Q changes state, and the pulse ends.
