HCPL-2611-520E

Logic Output Optoisolators Overview

The HCPL-2611-520E 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 5000 Vrms isolation voltage. The device supports a forward current of 10 mA with a typical forward voltage of 1.5 V. Key timing parameters include a rise time of 24 ns and a fall time of 10 ns. It handles a maximum output current of 50 mA and dissipates up to 85 mW. The component functions within a temperature range of -40°C to +85°C and utilizes a PDIP-8 Gull Wing package.

Logic Output Optoisolators Feature Summary

• Integrates a GaAsP light emitting diode with an integrated high gain photo detector for optical coupling.
• Features Schottky clamping on the output stage to enhance switching speed and noise immunity.
• Provides high common-mode transient immunity of 15 kV/µs for reliable signal transmission in noisy environments.

Logic Output Optoisolators Applications

• Industrial networking systems requiring electrical isolation between diverse voltage levels.
• General-purpose logic gate applications utilizing optical coupling for signal integrity.
• Digital communication interfaces demanding high-speed data transfer with galvanic isolation.

Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix to confirm the packaging type, as variants exist in tube, reel, cut tape, and MouseReel formats. Confirm RoHS compliance status through official documentation, as some listings indicate detailed or non-compliant statuses depending on the revision. Ensure the selected variant matches the required mounting style and lead configuration for the target PCB design.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside robust common-mode transient immunity. The open collector output necessitates an external pull-up resistor; ensure the circuit design accommodates this requirement. Compare the 5000 Vrms isolation rating against system safety standards. Consider the thermal dissipation limits of 85 mW when designing for high ambient temperatures or dense packing configurations.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-2611 series of high-speed optocouplers manufactured by Broadcom Limited. The series is designed for applications requiring fast signal transmission across isolated barriers. The HCPL-2611-520E specifically denotes a variant with defined packaging and potentially updated compliance specifications compared to earlier revisions like the HCPL-2611-000E.

Logic Output Optoisolators Replacement Considerations

Direct substitutes may include other single-channel high-speed optocouplers from Broadcom such as the HCPL-2611-000E, though packaging and isolation ratings must be verified. Cross-manufacturer replacements require matching the 10 Mb/s data rate, 5000 Vrms isolation, and open collector output topology to ensure functional compatibility.
