Optoisolators are components used to prevent electrical signals from passing from one side of the circuit to the other, as well as providing a degree of galvanic isolation. A logic-output optoisolator, such as the HCPL-0211-060E, is designed to interface between digital logic signals; for example, when transferring 5V TTL signals across an isolation barrier. The HCPL-0211-060E application field and working principle will be discussed in this article.

The HCPL-0211-060E is a highly integrated optoisolator with a GaAIAS LED encased in an 8-pin DIP package. This device provides a logic level coupling between two sides of a circuit, with a high common-mode transient immunity up to 2000V/us. It is designed for use in automotive and industrial control applications. With a maximum collector-emitter voltage of 60V, the HCPL-0211-060E can be used in line-failure detection systems and other critical applications.

The working principle of the HCPL-0211-060E is based on the photoelectric effect, where an electrical signal is transmitted across an isolation barrier via light. The HCPL-0211-060E has an integrated LED which receives the power input from the ground side of the circuit and in response emits light. The emitted light is then received by a light-sensitive component on the load side of the circuit, generating an electrical signal. The output voltage of the optical coupler is then applied to the logic input to switch the logic gate.

The HCPL-0211-060E is equipped with an internal shield structure that creates a barrier to minimize interference from the environment. The device also has an internal current limiter to ensure a safe and predictable operation, reducing the chance of damage from an over-current due to a short or overload. The output is designed with a high-speed switching capability of 10 MHz, making the HCPL-0211-060E suitable for high-speed data transmission.

In summary, the HCPL-0211-060E is an 8-pin DIP logic-output optoisolator that provides galvanic isolation between input and output signals while providing logic level coupling. It has an integrated LED that transmits a signal via light across an isolation barrier. The device also provides a high common-mode transient immunity up to 2000V/us and a maximum collector-emitter voltage of 60V. With an internal shield structure and current limiting, the HCPL-0211-060E is an excellent choice for applications requiring secure and reliable data transmission.
