description  
The ’LV221A devices are dual multivibrators  
designed for 2-V to 5.5-V V operation. Each  
CC  
multivibrator has a negative-transition-triggered  
(A) input and a positive-transition-triggered (B)  
input, either of which can be used as an inhibit  
input.  
NC – No internal connection  
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.  
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

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