HCPL-2612

Overview

The HCPL-2612 is a high-speed optocoupler featuring a single channel with an open collector output. It operates at a data rate of 10 Mb/s and provides an isolation voltage of 3750 Vrms. The device supports a forward current of up to 60 mA and delivers an output current of 50 mA per channel. Common mode transient immunity is rated at a minimum of 3.5 kV/µs, ensuring reliable signal transmission in noisy environments.

Feature Summary

• Combines a GaAsP LED with an integrated input current regulator for stable operation
• Features high common mode transient immunity for robust noise rejection
• Utilizes an open collector output configuration for flexible interfacing

Applications

• Industrial communication bus systems
• General-purpose digital isolation
• Long-line receiver applications

Procurement Notes

Verify the specific suffix (e.g., -000E, -300E) to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required operating temperature range and mounting preferences. Cross-reference official datasheets for pinout consistency before integration into PCB designs.

Selection Notes

Select this component when high-speed digital isolation is required alongside strong noise immunity. The integrated current regulator simplifies drive circuit design compared to standard optocouplers. Consider the open collector output topology for compatibility with various logic families.

Part Context

This part belongs to the HCPL-26xx series of high CMR line receiver optocouplers. It is designed to replace older discrete isolation solutions by providing integrated regulation and high-speed performance in a compact DIP or surface-mount package.

Replacement Considerations

Check HCPL-2611 for similar functionality with different current ratings. Verify HCPL-2602 if a dual-channel configuration is needed instead of a single channel.
