74AHC123A-Q100 74AHCT123A-Q100 Dual retriggerable monostable multivibrator with reset Rev. 2 17 June 2020 Product data sheet 1. General description The 74AHC123A-Q100 74AHCT123A-Q100 is a dual retriggerable monostable multivibrator with reset. The basic output pulse width is programmed by selection of external components (R and C ). Once triggered this basic pulse width may be extended by retriggering either EXT EXT of the edge triggered inputs (nA or (nB). By repeating this process, the output pulse period (nQ = HIGH, nQ = LOW) can be made as long as desired. Alternatively, an output delay can be terminated at any time by a LOW-going edge on input nRD. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments. This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications. 2.
