HCPL-2531-000ME

Logic Output Optoisolators Overview

The HCPL-2531-000ME is a dual-channel high-speed optocoupler manufactured by Broadcom, distributed by Flip Electronics. It features an AlGaAs LED input and integrated photo-detector with separate bias connections to minimize base-collector capacitance, enabling speeds up to 1 MBd. Key electrical parameters include a maximum forward current of 25 mA, a minimum current transfer ratio of 19%, and a maximum collector output current of 8 mA. The device offers isolation voltages ranging from 3750 Vrms to 5000 Vrms depending on the specific variant suffix, operates within a temperature range of -55°C to 100°C, and is available in 8-pin PDIP packages.

Logic Output Optoisolators Feature Summary

• Dual-channel architecture with separate photodiode bias and output transistor collector connections for enhanced speed
• High data rate capability up to 1 MBd due to reduced base-collector capacitance
• TTL and CMOS logic compatibility for direct interface with digital circuits
• Comprehensive safety certifications including UL, IEC, EN, and CSA recognition

Logic Output Optoisolators Applications

• Industrial communication interfaces requiring galvanic isolation
• Signal transmission between microcontrollers and peripheral devices
• Noise-immune data links in electrically noisy environments
• Logic-level signal coupling in automated control systems

Logic Output Optoisolators Procurement Notes

Verify the manufacturer origin carefully, as the part number is primarily associated with Broadcom while Flip Electronics acts as a distributor. Confirm the specific isolation voltage rating (3750 Vrms or 5000 Vrms) and package type (PDIP vs SO-8) required for your design, as these vary by suffix. Ensure the RoHS compliance status matches your environmental regulations, noting that some variants may be lead-free while others are not. Cross-reference the datasheet version to confirm pinout consistency with legacy designs.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required over conventional phototransistor couplers. The separate bias terminal allows for faster switching times compared to standard optocouplers. Consider the operating temperature range and isolation voltage requirements relative to the specific application environment. Verify that the input current limits and output drive capabilities align with the connected logic families. Check for alternative package options if surface mount technology is preferred over through-hole mounting.

Logic Output Optoisolators Part Context

This device belongs to the HCPL-2530/HCPL-2531 family of dual-channel high-speed optocouplers. It shares architectural similarities with single-channel counterparts like the 6N135 but provides two isolated channels in one package. The family utilizes AlGaAs LEDs and integrated photo-detectors to achieve superior performance over traditional phototransistor-based isolators. It is designed for applications demanding reliable signal transmission across electrical boundaries at data rates up to 1 MBd.

Logic Output Optoisolators Replacement Considerations

Direct substitutes include the HCPL-2530 (single channel) or HCPL-4502 (dual channel) for similar performance characteristics. The ON Semiconductor equivalent HCPL2531VM offers comparable specifications with potential packaging differences. Verify pinout compatibility and isolation voltage ratings before substitution. Note that the HCPL-2531-060 variant has a lower isolation voltage of 3750 Vrms compared to the 5000 Vrms found in other versions.
