description/ordering information
The ’AHC123A devices are dual retriggerable
monostable multivibrators designed for 2-V to
5.5-V VCC operation.
These
edge-triggered
multivibrators
feature
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.
