HCNW137-300E

Logic Output Optoisolators Overview

The HCNW137-300E is a high-speed logic output optocoupler featuring an 8-SO surface-mount package. It integrates a GaAsP LED with a Schottky-clamped open collector photodetector to achieve a data rate of 10 MBd. Key electrical parameters include a propagation delay of 100 ns (typical rise/fall times of 24 ns/10 ns), an isolation voltage of 5000 Vrms, and a common-mode transient immunity of 5 kV/µs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum forward current of 20 mA.

Logic Output Optoisolators Feature Summary

• High-speed signal transmission capability up to 10 MBd for efficient data isolation.
• Schottky clamping on the output stage ensures fast switching speeds and reduced overshoot.
• Integrated high-gain photo detector provides reliable logic-level output signals.
• Robust insulation performance with 5000 Vrms isolation rating for safety.

Logic Output Optoisolators Applications

• Computer peripheral interfaces demanding rapid signal transfer
• Power supply feedback loops for isolated control applications

Logic Output Optoisolators Procurement Notes

Verify the specific suffix designation to confirm the packaging format, as the base model may be available in different configurations. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies by region. Ensure the selected variant matches the required thermal and mechanical constraints for the target assembly process.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is critical for system integrity. The 10 MBd data rate suits applications requiring rapid communication between isolated domains. Consider the 8-SO package for space-constrained designs. Evaluate the 5 kV/µs CMTI rating against noise environments to ensure stable operation without false triggering during transient events.

Logic Output Optoisolators Part Context

This part belongs to the HCNW137 series of high-speed optocouplers from Broadcom Limited. It serves as a modern replacement for legacy devices like the 6N137, offering improved speed and reliability. The series is designed for applications where traditional optocouplers are too slow, providing a balance between performance and cost in industrial and computing sectors.

Logic Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers include the 6N137-300E and HCPL-2631. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure that any alternative device meets or exceeds the required isolation voltage and data rate specifications for the specific application context.
