The 74HC123-Q100; 74HCT123-Q100 are high-speed Si-gate CMOS devices and are pin compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.\n The 74HC123-Q100; 74HCT123-Q100 are dual retriggerable monostable multivibrators with output pulse width control by three methods:\nThe basic pulse is defined by the selection of the external resistor (REXT) and capacitor (CEXT).Once triggered, the basic output pulse width may be extended by retriggering the gated active LOW-going edge input (nA) or the active HIGH-going edge input (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, which also inhibits the triggering.An internal connection from nRD to the input gates makes it possible to trigger the circuit by a HIGH-going signal at input nRD. Schmitt trigger action in the nA and nB inputs, makes the circuit highly tolerant to slower input rise and fall times.\n This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.\n
