EL2631

Logic Output Optoisolators Overview

The EL2631 is a high-speed, dual-channel logic output optoisolator manufactured by Everlight Electronics. It features an 850 nm AlGaAs LED coupled to a high-speed integrated photodetector with open-collector outputs. The device supports data rates up to 10 Mbps and provides a common-mode transient immunity (CMTI) of 10 kV/µs. It operates within a supply voltage range of 4.5 V to 5.5 V and offers an isolation voltage of 5000 Vrms. Key electrical parameters include a propagation delay of approximately 100 ns and a forward current rating of 20 mA.

Logic Output Optoisolators Procurement Notes

Verify the manufacturer marking on the component body to confirm it is produced by Everlight Electronics Co Ltd, distinguishing it from similar part numbers like HCPL2631M which may be sourced from other manufacturers such as onsemi or Avago. Ensure the ordering suffix matches the required package type and temperature grade specified in the official Everlight datasheet. Cross-reference the date code and lot number against the distributor's certificate of authenticity to guarantee component integrity and traceability.

Logic Output Optoisolators Selection Notes

Select the EL2631 when dual-channel isolation with high-speed performance is required. Its 10 Mbps data rate and 10 kV/µs CMTI make it suitable for noisy industrial environments. Compare its pinout and electrical characteristics against alternatives like the HCPL2631M to ensure compatibility with existing circuit designs. Consider the open-collector output capability if wired-OR logic is needed for system integration.

Logic Output Optoisolators Part Context

The EL2631 belongs to the family of high-speed logic output optocouplers designed for robust signal transmission across isolated boundaries. It utilizes an AlGaAs LED and integrated photodetector technology to achieve fast switching speeds. This component is part of Everlight's portfolio of optoelectronic devices aimed at providing reliable isolation in digital circuits, competing with similar offerings from other semiconductor manufacturers.

Logic Output Optoisolators Replacement Considerations

The HCPL2631M from onsemi/Avago is a functionally equivalent dual-channel high-speed optocoupler with identical pinout and specifications. Verify that the replacement source confirms the same 10 Mbps speed and 10 kV/µs CMTI ratings before substitution.
