Texas Instruments SN74LS221D is a dual monostable multivibrator from the 74LS series. This device offers a fixed, predictable output pulse width of 45 ns, controllable via an external timing capacitor and resistor. Each of the two independent circuits features a Schmitt trigger input for improved noise immunity and a robust output drive capability of 400µA high and 8mA low. Operating within a 4.75V to 5.25V supply range and a 0°C to 70°C temperature range, the SN74LS221D is housed in a 16-SOIC package suitable for surface mounting. This component is commonly utilized in industrial control systems, data acquisition, and timing generation applications requiring precise pulse shaping and delay.
