Logic Output Optoisolators Procurement Notes

Verify the specific suffix #200 against the official datasheet to confirm pin configuration and material specifications. Ensure that the procurement source provides valid traceability documentation required for MIL-PRF-38534 Class K components. Confirm that the supplier is an authorized distributor to guarantee authenticity and prevent counterfeit parts from entering the supply chain.

Logic Output Optoisolators Selection Notes

Select this component when high reliability and radiation hardness are critical requirements. The wide operating temperature range makes it suitable for aerospace and industrial applications. Consider the 5 Mb/s data rate and low input current for compatibility with existing logic interfaces. Verify that the hermetic seal meets the environmental protection needs of the target application.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-520K series of high-speed optocouplers. It is distinguished by its Class K qualification under MIL-PRF-38534, indicating suitability for space and defense applications. The series offers various package options, but the #200 suffix specifically denotes the hermetically sealed ceramic DIP variant designed for maximum environmental resilience.

Logic Output Optoisolators Replacement Considerations

Direct replacements must maintain the same MIL-PRF-38534 Class K qualification and hermetic sealing. Verify that substitute parts match the 5 Mb/s data rate and 1500 VDC isolation voltage. Ensure the replacement package matches the 8-DIP footprint and pinout to avoid PCB redesign.
