NE556D Description

Short technical summary and product information.

The NE556D is a dual monolithic timing circuit from STMicroelectronics, designed for stable time delays and oscillation. It operates in both astable and monostable modes, controlled by external resistors and capacitors. This IC supports a wide supply voltage range from 4.5V to 16V and can operate at frequencies up to 500kHz.

 

The NE556D features TTL-compatible inputs and outputs that can source or sink up to 200mA. Its temperature stability is rated at 0.005% per degree Celsius, ensuring reliable performance across its operating temperature range of 0°C to 70°C. The device is housed in a compact 14-SOIC surface-mount package, making it suitable for various electronic designs.

 

With its dual timer configuration, the NE556D offers flexibility for applications requiring precise timing control, such as pulse generation, waveform shaping, and sequential timing circuits. Its robust design and versatile functionality make it a staple component in many electronic systems.
