ELW137

Logic Output Optoisolators Overview

The ELW137 is a high-speed logic output optocoupler manufactured by Everlight Electronics Co Ltd. It features an 8-pin DIP wide body package and supports a data rate of 10 Mbps. The device provides an isolation voltage of 5000 Vrms with an open collector output capable of sourcing up to 50 mA per channel. It operates within a temperature range of -40°C to +85°C and includes a single channel configuration.

Logic Output Optoisolators Feature Summary

• High-speed signal transmission capability for digital logic applications
• Wide body 8-pin DIP packaging for robust mechanical stability
• Open collector output interface compatible with standard logic families

Logic Output Optoisolators Applications

• Digital communication interfaces requiring galvanic isolation
• Microprocessor system isolation for noise immunity
• Industrial control circuit signal transfer

Logic Output Optoisolators Procurement Notes

Verify the specific suffix variant (e.g., TA, TB) against the required pinout and electrical specifications before ordering. Confirm that the 8-pin DIP package aligns with the target PCB footprint. Ensure the 5000 Vrms isolation rating meets the safety requirements of the end application environment.

Logic Output Optoisolators Selection Notes

Select this component when a 10 Mbps data rate and 5000 Vrms isolation are required in a through-hole DIP format. Compare the open collector output drive strength against load requirements. Consider thermal management within the specified -40°C to +85°C operating range during design integration.

Logic Output Optoisolators Part Context

This part belongs to the ELW137 series of high-speed photocouplers from Everlight. It is functionally similar to industry-standard 6N137 devices but utilizes Everlight's specific manufacturing process. The series is designed for applications demanding fast switching speeds and reliable electrical isolation between input and output circuits.

Logic Output Optoisolators Replacement Considerations

Direct pin-compatible replacements include the 6N137S(TA) and 6N137S(TB). Verify that substitute parts match the 10 Mbps speed and 5000 Vrms isolation ratings. Check for any differences in forward voltage or output current capabilities that may affect circuit performance.
