description/ordering information  
The SN74LV123A is a dual retriggerable monostable multivibrator designed for 2-V to 5.5-V V  
operation.  
CC  
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.  
The output pulse duration is programmable by selecting external resistance and capacitance values. The  
external timing capacitor must be connected between C  
and R /C  
(positive) and an external resistor

connected between R /C  
resistance between R /C and V . The output pulse duration also can be reduced by taking CLR low.

CC  
Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input  
pulse. The A, B, and CLR inputs have Schmitt triggers with sufficient hysteresis to handle slow input transition  
rates with jitter-free triggering at the outputs.
