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.
