The ’LV123A devices are dual retriggerable monostable multivibrators designed for 2-V to 5.5-V V_CC operation.

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_ext and R_ext/C_ext (positive) and an external resistor connected between R_ext/C_ext and V_CC. To obtain variable pulse durations, connect an external variable resistance between R_ext/C_ext and V_CC. The output pulse duration also can be reduced by taking CLR low.
