HCPL0639R2

Logic Output Optoisolators Overview

The HCPL0639R2 is a high-speed, dual-channel logic gate optocoupler from onsemi's HCPL series. It features an AlGaAS LED coupled to a high-speed integrated photodetector logic circuit. Key electrical parameters include a data rate of 10 Mbps, isolation voltage of 3750 Vrms, and common-mode transient immunity (CMTI) of 25 kV/µs. The device operates with a supply voltage range of 4.5V to 5.5V, has a typical rise time of 17ns and fall time of 5ns, and supports a maximum forward current of 15mA per channel. It is housed in an 8-SOIC package.

Logic Output Optoisolators Feature Summary

• Dual-channel architecture providing independent signal isolation for two separate circuits within a single compact package.
• High common-mode transient immunity of 25 kV/µs ensures reliable operation in electrically noisy environments.
• Integrated Schottky clamping on the open-collector outputs prevents saturation and enhances switching speed.
• Utilizes an AlGaAS LED source coupled with high-speed integrated photodetector logic for fast data transmission.

Logic Output Optoisolators Applications

• High-speed serial communication interfaces requiring galvanic isolation
• Industrial control systems with significant ground potential differences
• Power electronics gate drive circuits needing fast signal transfer
• Data acquisition systems isolating analog-to-digital converter stages

Logic Output Optoisolators Procurement Notes

Verify the specific suffix R2 indicates reel packaging when ordering. Confirm that the 8-SOIC footprint matches the target PCB design. Ensure the 4.5V to 5.5V supply voltage range aligns with the system logic levels. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate the 25kV/µs CMTI requirement against the application's noise environment.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation at 10 Mbps is required. The open-collector output necessitates external pull-up resistors; ensure these are compatible with the destination logic voltage. Compare CMTI specifications against other optocouplers if the application involves high dv/dt noise. Consider the 8-SOIC package size constraints relative to available board space. Verify thermal dissipation requirements given the 85 mW power dissipation rating.

Logic Output Optoisolators Part Context
