HCPL-0611

Logic Output Optoisolators Overview

The HCPL-0611 is a high-speed, TTL-compatible optocoupler manufactured by Broadcom Limited. It integrates a GaAsP light-emitting diode with an integrated high-gain photo detector featuring Schottky-clamped open-collector outputs. The device supports data rates up to 10 MBd and offers an isolation voltage of 3750 Vrms. Key electrical parameters include a maximum forward current of 10 mA, a typical rise time of 24 ns, and a fall time of 10 ns. It operates within a temperature range of -40°C to +85°C and provides high common-mode transient immunity.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., -500E, -560E) to confirm packaging type such as tape-and-reel or cut tape. Ensure the manufacturer designation matches current Broadcom Limited branding following the Avago acquisition. Confirm RoHS compliance status and lead times directly with authorized distributors prior to ordering.

Logic Output Optoisolators Selection Notes

Select this component for applications requiring high-speed digital isolation with TTL compatibility. Consider the 10 MBd data rate and low input current requirements when designing driver circuits. Evaluate the SOIC-8 package dimensions against PCB layout constraints and verify thermal dissipation capabilities for the intended operating environment.

Logic Output Optoisolators Part Context

The HCPL-0611 belongs to the HCPL series of high-speed optocouplers from Broadcom. Originally developed by Avago Technologies, the product line continues under Broadcom Limited after corporate restructuring. This series is designed for robust performance in noisy industrial environments where galvanic isolation is critical.

Logic Output Optoisolators Replacement Considerations

Direct replacements may include other high-speed optocouplers from the same family with compatible pinouts and electrical characteristics. Verify functional equivalence regarding enable inputs and output configurations before substitution.
