74LV123: Dual retriggerable monostable multivibrator with reset (Based on PIP 74LV123)

The 74LV123 is a low-voltage Si-gate CMOS device and is pin and function compatible with the 74HC123; 74HCT123. It is a dual retriggerable monostable multivibrator which uses three methods to control the output pulse width:

Schmitt-trigger action in the nA and nB inputs makes the circuit highly tolerant of slower input rise and fall times.
