NE556N Description

Short technical summary and product information.

The NE556N from STMicroelectronics is a dual precision timer integrated circuit designed for astable or monostable operation. It provides two independent timing circuits per package, capable of generating precise time delays from microseconds to hours.

 

Key electrical characteristics include a maximum frequency of 500kHz, a wide operating supply voltage range of 4.5V to 16V, and a supply current of 20mA. The output can sink or source up to 150mA, and it is TTL-compatible. The device operates within a temperature range of 0°C to 70°C.

 

This timer IC is suitable for a variety of applications such as pulse shaping, missing pulse detection, tone-burst generation, pulse-width and pulse-position modulation, sequential timing, and general application timing.

 

The NE556N is available in a 14-DIP package, designed for through-hole mounting.
