DESCRIPTION/ORDERING INFORMATION
The SN74LVC1G123 is a single retriggerable monostable multivibrator designed for 1.65-V to 5.5-V VCC
operation.
This monostable multivibrator 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.
