HCPL2611M

Logic Output Optoisolators Overview

The HCPL2611M is a single-channel high-speed logic gate output optocoupler from the HCPL-26xxM series, manufactured by onsemi. It features an open-collector phototransistor output and supports data rates up to 10 MBd. The device provides electrical isolation with a minimum common-mode rejection of 10 kV/µs. Key electrical parameters include a forward current of 5 mA, a maximum collector-emitter voltage of 30 V, and a propagation delay of 90 ns. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin DIP package.

Logic Output Optoisolators Procurement Notes

Verify that the part number suffix 'M' corresponds to the specific RoHS-compliant or tape-and-reel variant required for your assembly process. Confirm the manufacturer is onsemi, as this component was originally developed by Broadcom/Avago and may be sourced from other distributors holding legacy inventory. Ensure the datasheet version matches the production batch specifications.

Logic Output Optoisolators Selection Notes

Select this component when a single channel of high-speed digital isolation is required between TTL or CMOS logic circuits. It is suitable for applications demanding fast response times and robust noise immunity. Consider the open-collector output configuration for level shifting capabilities. Verify that the 10 MBd data rate meets the system's bandwidth requirements before finalizing the design.

Logic Output Optoisolators Part Context

The HCPL2611M belongs to the HCPL-26xxM family of high-speed optocouplers. This series is designed to replace older generations like the HCPL-2611 with improved manufacturing processes and compliance standards. It shares functional similarities with the 6N137 but offers different packaging and sourcing options depending on the manufacturer.

Logic Output Optoisolators Replacement Considerations

onsemi recommends the HCPL26xxM series as the new equivalent part number for legacy designs. Direct pin-compatible replacements may include the HCPL-2611 from other manufacturers, though electrical characteristics should be verified against the specific datasheet.
