The 74AHC123A and 74AHCT123A are dual retriggerable monostable multivibrators wiht reset and output pulse width control by three methods. They are silicon-gate CMOS devices that are pin compatible ...

If we are using a multivibrator whose timing is determined by analog means, we will need to take component tolerances into account. In a recent column on the topic of “Registers vs. Latches vs.
