The 74HC123; 74HCT123 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. Inputs include clamp diodes. This enables the use of current
limiting resistors to interface inputs to voltages in excess of VCC.
Schmitt-trigger action in the nA and nB inputs, makes the circuit highly tolerant to slower input rise
and fall times
