OPI1280-066

Optoisolators are essential components in many electronic devices. The OPI1280-066 is a transistor output optoisolator that contains a photovoltaic cell and photodiode. The device is designed to isolate two circuits that must be electrically connected but must maintain separate power sources.

The OPI1280-066 features a wide range of applications, from industrial control and automation systems to medical and broadcast equipment. It is particularly well-suited for low-speed digital logic isolation, such as I2C or SPI, as well as industrial control applications. The device is designed to provide up to 2500VAC (peak) isolation and has an industry-standard 8-Lead PDIP package.

The OPI1280-066 uses a photovoltaic cell and photodiode configuration to create a logic-level optoisolator. The photodiode acts as the optocoupler’s input, and detects light in the LED’s output. When the photodiode detects the light, it allows a small amount of current to pass through the optocoupler, which is then amplified by the NPN transistor in the output stage. This amplified signal drives the output high, completing the optoisolation process.

Because the photodiode does not require any power to detect the light, the OPI1280-066 only needs an input signal to operate. This makes it ideal for applications that require high isolation at low power and low cost. Additionally, the device conforms to the IEC 61000-4-2 ESD standard, providing the highest level of electrostatic discharge immunity. The OPI1280-066 also has a 10 μs minimum propagation delay, so it is fast enough for most applications.

Overall, the OPI1280-066 is a reliable and cost-effective optoisolator that can provide up to 2500VAC (peak) of isolation. The device is ideal for low-speed digital logic isolation and industrial control applications, and with its conformal coating and low EMI properties, it is a great choice for commercial and medical equipment. With its 8-lead PDIP package, the OPI1280-066 is easy to integrate and reliable enough to use in any application.
