Pins: 16
Operating Voltage: 4.5 V
Max Voltage (typical range): 6 V
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).
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
