74HC423 multivibrator equivalent, dual retriggerable monostable multivibrator.
* DC triggered from active HIGH or active LOW inputs
* Retriggerable for very long pulses up to 100 % duty factor
* Direct reset terminates output pulse
*.
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 w.
