HCNW2611-000E

Logic Output Optoisolators Overview

The HCNW2611-000E is a high-speed logic output optoisolator manufactured by Broadcom Limited. It features a single channel with an open collector, Schottky-clamped output. The device supports data rates up to 10 MBd and provides isolation voltages of 5000 Vrms or 3750 Vrms depending on the specific certification variant. Key electrical parameters include a maximum propagation delay of 100 ns, typical rise and fall times of 24 ns and 10 ns respectively, and a minimum common-mode transient immunity (CMTI) of 15 kV/µs. It operates within a temperature range of -40°C to 85°C and is available in 8-DIP packages.

Logic Output Optoisolators Feature Summary

• Integrates a GaAsP LED with a high-gain integrated photo detector for digital signal transmission.
• Provides high common-mode transient immunity to tolerate noisy environments where conventional receivers fail.
• Features Schottky clamping on the output to prevent saturation and ensure fast switching speeds.

Logic Output Optoisolators Applications

• High-speed logic interfacing between different voltage domains.
• Input/output buffering in industrial control systems.
• Line receiving applications in electrically noisy environments.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., -000E vs -300E) to confirm package type (DIP vs SMD) and isolation rating before ordering. Confirm RoHS compliance status as some variants may not meet current regulations. Check lead times as availability varies significantly between distributors. Ensure the selected part matches the required CMTI specifications for the target application environment.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required with robust noise immunity. The open-collector output requires appropriate pull-up resistor selection based on the load voltage. Consider the package style (through-hole DIP or surface mount) based on PCB layout constraints. Verify that the input forward current limits are respected within the operating temperature range to maintain performance.

Logic Output Optoisolators Part Context

This part belongs to the HCNW series of high-speed optocouplers from Broadcom. These devices are designed to replace older TTL-compatible optocouplers while offering superior speed and noise rejection capabilities. The series is widely used in communication interfaces and industrial automation where reliable signal transfer across isolation barriers is critical.

Logic Output Optoisolators Replacement Considerations

Direct substitutes include the HCNW2611-000E variant which shares identical pinout and electrical characteristics. Other compatible parts in the family include the HCPL-2611, though verification of specific isolation ratings and package dimensions is required. Cross-referencing datasheets for propagation delay and CMTI values is essential for functional equivalence.
