Dual retriggerable monostable multivibrator with reset 74LV123PW-Q100J
The 74LV123-Q100 is a dual retriggerable monostable multivibrator with reset. The basic output pulse width is programmed by selection of external components (REXT and CEXT). Once triggered this basic pulse width may be extended by retriggering either 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. Control inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess VCC. Schmitt-trigger action at nA and nB inputs makes the circuit tolerant of slower input rise and fall times. This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
