HCPL2611SV

Logic Output Optoisolators Overview

The HCPL2611SV is a single-channel high-speed logic output optocoupler manufactured by onsemi. It features an AlGaAs LED coupled to a Schottky-clamped phototransistor with integrated circuitry for fast switching. Key electrical parameters include a data rate of 10 Mbps, isolation voltage of 2500 Vrms (with some sources citing 5000 Vrms), and common mode transient immunity of 10 kV/µs. The device operates within a supply voltage range of 4.5 V to 5.5 V, supports a maximum forward current of 50 mA, and delivers an output current of 50 mA. Propagation delays are typically 75 ns max, with rise/fall times around 50 ns/12 ns. It functions in temperatures from -40°C to +85°C.

Logic Output Optoisolators Procurement Notes

Verify the specific datasheet version as onsemi lists this part as obsolete or end-of-life in many regions. Confirm availability through authorized distributors or surplus markets. Ensure the package type matches your PCB design requirements, as SMD variants exist. Check for RoHS compliance status relevant to your manufacturing standards. Substitute parts may be required due to lifecycle status.

Logic Output Optoisolators Selection Notes

Select this component when high-speed isolation up to 10 Mbps is required with strong noise immunity. The open-collector output allows flexible interfacing with various logic families. Consider the 2500 Vrms isolation rating for safety-critical applications. Verify that the 50 mA output current meets load requirements. The wide operating temperature range suits harsh industrial conditions.

Logic Output Optoisolators Part Context

The HCPL2611SV belongs to onsemi's high-speed optocoupler family, designed for demanding digital isolation tasks. It shares architectural similarities with other HCPL-26xx series devices but offers optimized speed and noise characteristics. This component bridges legacy high-speed isolation needs with modern low-voltage logic levels, serving as a robust interface between noisy power stages and sensitive control electronics.

Logic Output Optoisolators Replacement Considerations

Public confirmed substitutes include HCPL-2611-000E (Broadcom) and HCPL-2611 (onsemi). Note that HCPL-2611SV is listed as obsolete by onsemi. Verify pinout compatibility and electrical specifications before substitution. Alternative packages like DIP may require adapter solutions if only SMD versions are available.
