HCNW2611-300E

Logic Output Optoisolators Overview

The HCNW2611-300E is a high-speed, single-channel optocoupler manufactured by Broadcom Limited. It integrates a GaAsP light-emitting diode with an integrated high-gain photodetector to provide digital signal isolation. The device features a data rate of 10 Mb/s and supports a maximum DC forward current of 20 mA. It offers a typical propagation delay of 100 ns with rise and fall times of 24 ns and 10 ns, respectively. The unit provides 3750 Vrms isolation voltage and operates within a temperature range of -40°C to +85°C. It utilizes an open collector output capable of sourcing 50 mA and is housed in an 8-PDIP surface-mount package.

Logic Output Optoisolators Feature Summary

• Integrates a GaAsP LED with a high-gain photodetector for efficient optical coupling
• Features Schottky-clamped open-collector output for fast switching performance
• Provides high common-mode transient immunity for noise-resistant signal transmission

Logic Output Optoisolators Applications

• Isolation of microcontroller I/O lines from noisy power domains
• Signal transmission in industrial control systems with high noise environments

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '300E' to confirm the surface-mount PDIP-8 packaging variant, as standard DIP versions exist. Ensure compliance with RoHS directives if required by project specifications, noting that some variants may have different regulatory statuses. Confirm lead times with authorized distributors due to potential supply fluctuations. Validate thermal management requirements for the SMD package during operation.

Logic Output Optoisolators Selection Notes

Select this component when a 10 Mb/s data rate and 3750 Vrms isolation are sufficient for the application. Consider the open-collector output configuration for compatibility with TTL logic levels. Evaluate the 20 mA forward current limit against drive circuit capabilities. Compare against HCPL-2611-300E for identical electrical performance but verify package differences between through-hole and surface-mount requirements.

Logic Output Optoisolators Part Context

This part belongs to the HCNW series of high-speed optocouplers designed for robust signal isolation. It complements the HCPL-2611 family by offering a surface-mount alternative. The device is engineered for applications demanding high common-mode rejection and fast response times in compact form factors suitable for modern PCB layouts.

Logic Output Optoisolators Replacement Considerations

HCPL-2611-300E is a confirmed substitute with identical electrical characteristics. Verify package compatibility as both utilize 8-PDIP SMD configurations. Ensure pinout alignment matches the target footprint before implementation.
