The SN74LS221DR from Texas Instruments is a dual monostable multivibrator integrated circuit. This component belongs to the LS technology family and is designed for applications requiring precise pulse generation.
Key electrical characteristics include a typical supply current of 27000µA, a maximum output low current (IOL) of 8mA, and a maximum output high current (IOH) of -0.4mA. The device operates within a supply voltage range of 4.75V to 5.25V, with a standard propagation delay of 45 ns. It features Schmitt-trigger input circuitry for enhanced noise immunity.
This multivibrator IC is housed in a 16-SOIC package, suitable for surface mounting. The operating temperature range is from 0°C to 70°C, making it appropriate for various commercial and industrial environments. Each of the two independent circuits can be triggered to generate a stable output pulse, with the pulse width adjustable via external timing components.
The SN74LS221DR is designed for applications where controlled pulse generation is critical, such as timing circuits, pulse shaping, and delay generation.
