Product Summary
The SN74AHC123APWR is a dual retriggerable monostable multivibrator which is designed for 2V to 5.5V VCC operation. The SN74AHC123APWR features output pulse-duration control by three methods. In the first method, the A input is low, and the B input goes high. In the second method, the B input is high, and the A input goes low. In the third method, the A input is low, the B input is high, and the clear (CLR) input goes high.
