Nexperia B.V. Dual retriggerable monostable multivibrator with reset 74AHC123ABQ,115

The 74AHC123A; 74AHCT123A is a dual retriggerable monostable multivibrator with reset. The basic output pulse width is programmed by selection of external components (R_EXT and C_EXT). Once triggered this basic pulse width may be extended by retriggering either of the edge triggered inputs (nAor (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.
