Procurement Notes

Verify the specific package variant and tape-and-reel specifications against the official Texas Instruments datasheet before procurement. Ensure that the selected component meets the required isolation voltage standards for the target application environment. Confirm availability through authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a single-channel digital isolator with a push-pull output is required. Consider the 200 kBd data rate limit and 5 µs propagation delay for timing-sensitive designs. Evaluate the 3540 Vpk isolation rating against system safety requirements. Compare performance metrics with alternative optocouplers if higher speed or different output configurations are needed.

Part Context

The OPI8012 belongs to the family of logic output optoisolators produced by Texas Instruments. These components are designed to provide electrical isolation between circuits while transmitting digital signals. The device utilizes an infrared LED and a photodetector to achieve galvanic isolation, ensuring safe operation in high-voltage environments.

Replacement Considerations

Consult the Texas Instruments official documentation for verified substitute part numbers. Cross-reference pinouts, isolation ratings, and electrical characteristics to ensure functional compatibility. Do not assume interchangeability without validating technical specifications against the original design requirements.
