• Data communication interfaces requiring galvanic isolation
• Logic gate driving applications with noise immunity requirements

Logic Output Optoisolators Procurement Notes

Verify the specific suffix matches the required package style, as the #500 designation typically indicates a PDIP-8 through-hole configuration. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Ensure the operating temperature range of -40°C to 85°C aligns with your thermal design constraints before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside strict voltage isolation standards. The 15 MBd speed and 10 kV/µs CMTI make it suitable for noisy environments. Consider the open collector output type for flexibility in pull-up resistor selection to match various logic voltage levels, ensuring proper interface matching with downstream microcontrollers or FPGAs.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-260L series of logic output optoisolators from Broadcom Limited. The series is designed for applications demanding high-speed data transfer across isolated barriers. The HCPL-260L#500 variant specifically utilizes a PDIP-8 package, distinguishing it from surface-mount variants like the HCPL-260L-500E which uses an SMD8 package.

Logic Output Optoisolators Replacement Considerations

Direct substitutes within the same family include HCPL-260L-500E for surface mount applications. Verify pinout compatibility and isolation voltage ratings when cross-referencing with other high-speed optocouplers. Ensure that any replacement maintains the 15 MBd data rate and 3750 Vrms isolation capability to preserve system integrity.
