HCPL0637R2

Logic Output Optoisolators Overview

The HCPL0637R2 is a high-speed, dual-channel logic output optoisolator manufactured by onsemi. It features a data rate of 10 Mbps and an isolation voltage of 3750 Vrms. The device utilizes Schottky-clamped phototransistor technology for enhanced performance. It operates within a temperature range of -40°C to +85°C. Key electrical parameters include a typical propagation delay of 75 ns, a maximum forward voltage of 1.75 V, and an output current capability of 15 mA per channel. The component is housed in an 8-pin SOIC surface-mount package.

Logic Output Optoisolators Feature Summary

• Dual-channel architecture providing independent signal isolation paths
• Schottky-clamped phototransistor output for improved switching speed
• High common-mode transient immunity suitable for noisy environments

Logic Output Optoisolators Applications

• Industrial automation control systems
• Data communication interfaces requiring galvanic isolation
• Power supply feedback loops

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'R2' indicates tape-and-reel packaging when sourcing components. Confirm that the 3750 Vrms isolation rating meets the safety requirements of the target application environment. Ensure compatibility with standard SOIC-8 footprint designs during PCB layout. Check for RoHS compliance status if required by regional regulations.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is necessary at speeds up to 10 Mbps. The Schottky-clamped output offers faster switching than standard phototransistors. Consider the 8-pin SOIC package size for space-constrained designs. Evaluate the 3750 Vrms isolation barrier against system voltage requirements.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-0637 series of high-speed optocouplers from onsemi. The series is designed for applications demanding fast digital signal transmission across isolated boundaries. The HCPL0637R2 variant specifically denotes the reel-packaged version of the dual-channel device.

Logic Output Optoisolators Replacement Considerations

Direct substitutes may include other dual-channel optocouplers with similar 10 Mbps data rates and SOIC-8 packages. Verify pinout compatibility and isolation voltage ratings before substitution. Ensure equivalent propagation delay characteristics are maintained for timing-sensitive circuits.
