VO2631

Logic Output Optoisolators Overview

The VO2631 is a dual-channel logic output optoisolator manufactured by Vishay Semiconductor Opto Division. It features an open-drain output configuration with a data rate of 10 MBd and isolation voltage of 5300Vrms. The device supports a supply voltage range of 4.5V to 5.5V, with a maximum DC forward current of 15mA and output current per channel of 50 mA. Operating temperature spans from -40°C to 100°C. Propagation delays are typically 75ns to 100ns, with rise/fall times of 23ns/7ns. Common packages include 8-DIP and 8-SMD.

Logic Output Optoisolators Feature Summary

• Dual-channel architecture providing independent signal isolation paths within a single component.
• High-speed logic output capability supporting data transmission rates up to 10 MBd.
• Robust electrical isolation rated at 5300Vrms for high-voltage noise immunity.
• Open-drain output stage designed for flexible interfacing with various digital logic families.

Logic Output Optoisolators Applications

• Industrial automation control systems requiring galvanic isolation
• Power electronics gate drive circuits for inverters and converters
• Communication interfaces in noisy electromagnetic environments
• Microcontroller input/output expansion with isolated signaling

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., X017T, X016) to confirm package type and CMTI rating. Confirm RoHS compliance status as required by project specifications. Check datasheet revisions for any pinout or parameter updates before finalizing design integration.

Logic Output Optoisolators Selection Notes

Select based on required isolation voltage and package preference. Ensure the open-drain output matches the pull-up requirements of the receiving circuit. Verify that the 10 MBd speed meets system timing constraints and that the operating temperature range covers environmental conditions.

Logic Output Optoisolators Part Context

The VO2631 belongs to Vishay's family of dual-channel 10 MBd optocouplers, sharing functional similarities with the VO2630 and VO4661. While the VO2630 offers lower CMTI, the VO2631 provides enhanced common-mode transient immunity in certain configurations. This series targets applications needing reliable high-speed digital isolation.

Logic Output Optoisolators Replacement Considerations

Direct substitutes include the VO2630-X007T for SMD packages with lower CMTI requirements, or the VO2631-X016 for DIP packages. Verify pin compatibility and isolation ratings when cross-referencing with other manufacturers' dual-channel logic optocouplers.
