74LS122 Description

Short technical summary and product information.

The 74LS122 by NTE Electronics is a versatile monostable multivibrator IC, functioning as a one-shot pulse generator. This component is designed to output a single, precisely timed pulse when triggered, making it invaluable for applications requiring specific delay durations or single-event signal generation.

 

Key electrical characteristics include a typical operating voltage of 5V, with the HC variant supporting a wider range of 2V to 6V. The chip features an integrated 10kΩ timing resistor, which can be used for basic timing configurations, or an external resistor can be connected for improved accuracy. The output current capabilities are notable, with the LS version capable of sinking up to 8mA and sourcing up to 0.4mA.

 

This 14-pin integrated circuit is suitable for through-hole mounting. Its ability to generate controlled output pulses is useful in various digital electronic projects for tasks such as timing control, debouncing switches, or creating specific pulse sequences. The pulse duration can be calculated using the formula t (ns) = 0.32 * R T * C ext * (1 + 0.7/R T ), where R T is in kΩ and C ext is in pF.
