Description
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).
