The DM74LS221N is a dual, highly stable, non-retriggerable one-shot multivibrator manufactured by ON Semiconductor. This device is designed for applications requiring precise pulse generation.
Key electrical characteristics include a typical propagation delay of 65 ns and an operating voltage range of 4.75V to 5.25V. It supports two independent circuits, offering flexibility in pulse timing. The output pulse width can be set externally using a resistor and capacitor, ranging from 30 ns to 70 seconds.
This component is housed in a 16-PDIP package suitable for through-hole mounting. It operates within a temperature range of 0°C to 70°C. The DM74LS221N is compatible with DTL and TTL logic levels and includes input clamp diodes for enhanced reliability.
Designed for stability, the DM74LS221N is compensated for VCC and temperature variations. Its features include hysteresis at the (B) input for improved noise immunity and a direct reset function to terminate the output pulse. The device is triggerable from the CLEAR input, offering versatile control options.
