HCPL2611W

Logic Output Optoisolators Overview

The HCPL2611W is a single-channel high-speed logic gate output optocoupler manufactured by onsemi. It features an open collector output and supports data rates up to 10 Mbit/s with a typical propagation delay of 50 ns. The device provides electrical isolation with a minimum common-mode rejection ratio (CMR) of 10 kV/µs. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin DIP package.

Logic Output Optoisolators Feature Summary

• High-speed logic gate output for fast signal transmission
• Open collector configuration for flexible interfacing
• High common-mode noise immunity

Logic Output Optoisolators Applications

• Isolated line receivers
• Computer peripheral interfaces
• Microprocessor system interfaces
• Digital isolation for A/D and D/A conversion

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'W' against official onsemi documentation to confirm package type and lead-free status, as generic HCPL-2611 listings may vary. Ensure the component matches the required isolation voltage and operating temperature range for your specific application environment before procurement.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required between circuits with different ground potentials. It is suitable for applications demanding fast response times and robust noise rejection. Verify that the input current requirements align with the driving source capabilities and that the open-collector output can handle the load voltage.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-2611 series of high-speed optocouplers originally developed by HP/Agilent and now produced by onsemi. It is designed to replace older logic gate optocouplers like the 6N137 in high-performance systems. The series is known for its TTL compatibility and reliable performance in noisy industrial environments.

Logic Output Optoisolators Replacement Considerations

onsemi recommends using the HCPL26xxM series as the new equivalent part number for this component. Designers should verify pinout compatibility and electrical specifications when transitioning from the legacy HCPL2611 to the newer M-series devices.
