HCPL2631SDVM

Logic Output Optoisolators Overview

The HCPL2631SDVM is a dual-channel high-speed logic gate optocoupler manufactured by onsemi. It features an 850nm AlGaAS LED optically coupled to integrated output ICs, providing open-collector outputs. The device supports data rates up to 10 Mbps with typical rise and fall times of 50 ns and 12 ns, respectively. It offers a minimum common-mode transient immunity (CMTI) of 5 kV/µs and an isolation voltage of 2500 Vrms. Operating within a supply voltage range of 4.5V to 5.5V, it handles a maximum forward current of 30 mA and delivers an output current of 50 mA per channel. The component is housed in an 8-SMD鸥翼 package and operates across a temperature range of -40°C to 100°C.

Logic Output Optoisolators Feature Summary

• Dual-channel architecture integrating two independent high-speed logic gates within a single package for efficient signal transmission.
• High common-mode transient immunity rated at a minimum of 5 kV/µs to maintain signal integrity in electrically noisy environments.
• Open-collector output configuration compatible with standard logic families, facilitating direct interfacing with microcontrollers and digital circuits.

Logic Output Optoisolators Applications

• Industrial communication systems requiring galvanic isolation between microprocessors and peripheral devices.
• Data acquisition systems where noise immunity and signal fidelity are critical for accurate measurement.
• Power electronics control circuits isolating low-voltage control logic from high-voltage power stages.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'SDVM' corresponds to the surface-mount 8-SMD鸥翼 package variant rather than the through-hole PDIP version. Confirm the operating temperature range extends to 100°C as specified for this SMD revision. Ensure compliance with RoHS directives and check for any recent Product Change Notices regarding manufacturing site or material declarations before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required within a compact surface-mount footprint. It serves as a suitable alternative to single-channel solutions like the 6N137 when space efficiency is prioritized. Consider the 5 kV/µs CMTI rating for applications involving rapid switching transients. Verify that the 50 mA output current capability meets the load requirements of the destination logic circuitry without external buffering.

Logic Output Optoisolators Part Context

This part belongs to the HCPL263x series of high-speed optocouplers, which also includes the single-channel HCPL2601 and HCPL2611 variants. The series utilizes advanced AlGaAS LED technology to achieve superior speed compared to standard phototransistor-based optocouplers. The HCPL2631 specifically addresses designs needing two isolated channels, offering a cost-effective solution for multi-line data buses.

Logic Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers include HCPL2631VM for the through-hole PDIP-8 package variant. For surface-mount replacements, verify availability of HCPL2631SDVM directly from onsemi distributors. Cross-reference with HCPL2631SD if reel packaging is acceptable instead of tube packaging.
