SN74LS40N Description

Short technical summary and product information.

The SN74LS40N is a versatile monostable multivibrator integrated circuit manufactured by Motorola Semiconductor. This component houses two independent monostable multivibrator circuits within a single 16-pin DIP package, making it suitable for precise timing generation and pulse shaping.

 

Key electrical characteristics include a fast propagation delay of 28 ns and a precisely controlled pulse width of 28 nanoseconds. It operates reliably within a supply voltage range of 4.75V to 5.25V, typical for 5V TTL logic systems. The device offers output currents of 400µA high and 8mA low. It is designed without Schmitt trigger inputs.

 

The SN74LS40N is specified for operation in environments ranging from 0°C to 70°C. Its through-hole mounting type and 16-DIP package facilitate easy integration into standard PCB designs. This IC is well-suited for applications requiring accurate delay circuits, frequency division, and digital control functions in industrial and consumer electronics.

 

Selection of the SN74LS40N is recommended for applications needing a dual monostable multivibrator with a 28 ns pulse width in a through-hole DIP package, particularly within 5V TTL logic systems. Ensure the operating temperature and package footprint align with your design requirements.
