Description

General part information

74LV221 Series

The SN74LV221A is a dual multivibrator designed for 2-V to 5.5-V VCCoperation. Each 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.

This edge-triggered multivibrator features output pulse-duration control by three methods. In the first method, theAinput is low and the B input goes high. In the second method, the B input is high and theAinput goes low. In the third method, theAinput 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 resistor between Rext/Cextand VCC. The output pulse duration also can be reduced by takingCLRlow.
