Product data sheet
1. General description
The 74HC123; 74HCT123 are high-speed Si-gate CMOS devices and are pin patible with Low-power Schottky TTL (LSTTL). They are specified in pliance with JEDEC standard no. 7A.
The 74HC123; 74HCT123 are dual retriggerable monostable multivibrators with output pulse width control by three methods:
1. The basic pulse is programmed by selection of an external resistor (REXT) and capacitor (CEXT).
2. 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...
