Description

General part information

SN74LV123A-Q1 Series

The SN74LV123A is a dual retriggerable monostable multivibrator designed for 2-V to 5.5-V VCCoperation.

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 Cextand Rext/Cext(positive) and an external resistor connected between Rext/Cextand VCC. To obtain variable pulse durations, connect an external variable resistance between Rext/Cextand VCC. The output pulse duration also can be reduced by taking CLR\ low.
