Texas Instruments SN74LS221DRE4 is a dual monostable multivibrator from the 74LS series. This device features independent internal timing functions, providing a stable output pulse width with a nominal duration of 45 ns. Each monostable circuit is triggered by a high or low logic level on its respective trigger input. The output pulse width is determined by an external resistor and capacitor. With two such circuits integrated into a single package, this component is suitable for applications requiring precise timing control. It operates within a voltage supply range of 4.75 V to 5.25 V and supports output currents of 400 µA high and 8 mA low. The SN74LS221DRE4 is housed in a 16-SOIC (0.154", 3.90mm Width) surface-mount package and is supplied on tape and reel. This component finds application in industrial automation and consumer electronics for timing and pulse generation functions.
