6N137#500

Overview

The Broadcom Limited 6N137#500 is a high-speed single-channel optocoupler featuring an open collector output with Schottky clamping. It supports data rates up to 10 Mb/s with typical rise and fall times of 24 ns and 10 ns, respectively. The device provides electrical isolation of 3750 Vrms and withstands common-mode transients of 15 kV/µs at Vcm=1000V. Operating on a supply voltage of 4.5V to 5.5V, it delivers a maximum output current of 50 mA and dissipates up to 85 mW. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• High-speed signal transmission capability supporting 10 Mb/s data rates
• Robust noise immunity with 15 kV/µs common-mode transient rejection
• Integrated Schottky clamping on the open collector output for fast switching
• TTL logic level compatibility for direct interface with digital systems

Applications

• Digital isolation in microprocessor-based communication interfaces
• Signal coupling in industrial control and automation systems

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels due to market availability variations. Confirm specific package markings and datasheet revisions match the required application specifications. Check RoHS compliance status and lead times as stock levels fluctuate. Ensure proper handling procedures are followed during storage and assembly to maintain device integrity.

Selection Notes

Select this component when high-speed digital isolation with strong noise immunity is required. The open collector output necessitates an external pull-up resistor for proper logic level generation. Consider thermal management requirements given the 85 mW power dissipation limit. Evaluate system voltage levels to ensure compatibility with the specified 4.5V to 5.5V supply range and TTL input thresholds.

Part Context

The 6N137 series represents a family of high-speed optocouplers designed for demanding digital isolation applications. The 6N137#500 variant specifically utilizes a PDIP-8 package configuration. This part belongs to Broadcom's legacy high-performance optoelectronics lineup, offering reliable performance for isolating noisy environments from sensitive logic circuits while maintaining signal integrity at high frequencies.

Replacement Considerations

The HCNW137-500E is a confirmed equivalent replacement offering identical functional specifications and pinout compatibility. Verify that substitute sources provide the same insulation voltage ratings and transient immunity characteristics. Ensure packaging differences do not impact board layout constraints or thermal performance requirements.
