5-V VCC operation.
This edge-triggered 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.
