General Description
The 74HC423 is a dual retriggerable monostable multivibrator with output pulse width control by two methods.
The basic pulse time is programmed by selection of an external resistor (REXT) and capacitor (CEXT).
Once triggered, the basic output pulse width may be extended by retriggering (nA) or (nB).
Key Features
- DC triggered from active HIGH or active LOW inputs.
- Retriggerable for very long pulses up to 100 % duty factor.
- Direct reset terminates output pulse.
- Schmitt-trigger action on all inputs except for the reset input.
- Complies with JEDEC standard no. 7A.
- Input levels:.
- For 74HC423: CMOS level.
- ESD protection:.
- HBM JESD22-A114F exceeds 2000 V.
- MM JESD22-A115-A exceeds 200 V.
- Specified from 40 C to +85 C and from 40 C to +125 C 3. Orderin.
