Optoisolators are widely applied in the protection of electronic electrical circuits from high voltage exposure and damage caused by short-circuits or overvoltage conditions. In particular, the ACPL-2672L optoisolator model is one of the most widely used optoisolators on the market today, offering superior performance in a very small package.

The ACPL-2672L optoisolator model is a logic output optoisolator that provides reliable electrical isolation between input and output circuit elements, while still transferring digital signals from one circuit to another without interference or degradation. This type of optoisolator utilizes a photovoltaic cell (light element) to act as an interface between the two circuits. This photovoltaic cell uses a small amount of electrical power to activate a LED light, which is then converted to an electrical signal by a light-sensitive semiconductor.

The primary application field of the ACPL-2672L optoisolator is that of non-volatile memory, especially in FPGAs and microprocessors. This optoisolator helps protect these devices from accidental or deliberate overvoltage conditions which could cause significant damage. It also allows for greater levels of reliability and accuracy when transferring digital signals between two circuits. As it is typically a low-cost solution, it has been widely adopted by many electrical and electronics industries.

In terms of working principle, the ACPL-2672L optoisolator comprises of an integrated light-emitting diode (LED) and an integrated photodiode located within the same chip. The light from the LED serves as an input, and the photodiode is used to detect the light and generate a small current as its output. This output is then replicated in the signal path of the two circuits to be connected, ensuring a strong electrical bond between the two and preventing any degradation or interference.

Additional features of the ACPL-2672L optoisolator include protection against transients and overvoltage conditions, with excellent noise immunity. It has a wide common mode transient immunity range of up to 15kV/μs, allowing for superior protection against lightning-induced overvoltage transients. Furthermore, it offers an improved data transfer rate and reliability, along with a low input voltage operating range of 3.5V to 5.5V.

In conclusion, the ACPL-2672L optoisolator is a logic output optoisolator designed to provide superior electrical isolation between input and output circuit elements while still allowing for reliable digital signal transfer. It is primarily used to provide protection for non-volatile memory devices such as FPGAs and microprocessors, and is widely adopted for its affordability and advanced features such as enhanced noise immunity. On the basis of its working principle, the ACPL-2672L optoisolator utilizes an integrated light-emitting diode (LED) and photodiode, with the LED serving as an input and the photodiode generating the output small current.
