HCPL-7723-520

Logic Output Optoisolators Overview

The HCPL-7723-520 is a single-channel high-speed optocoupler manufactured by Broadcom Limited. It features a push-pull output stage and supports data rates up to 50 MBd with a pulse width distortion of 2 ns. The device provides an isolation voltage of 5000 Vrms and a common mode transient immunity (CMTI) of 10 kV/µs. Key electrical parameters include a forward current of 10 mA, forward voltage of 5 V, rise time of 8 ns, fall time of 6 ns, and maximum power dissipation of 150 mW. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin DIP gull-wing package.

Logic Output Optoisolators Feature Summary

• Push-pull output configuration for fast signal transitions
• High common mode transient immunity of 10 kV/µs
• CMOS-compatible input interface

Logic Output Optoisolators Applications

• Industrial fieldbus isolation such as PROFIBUS and DeviceNet
• Isolated analog-to-digital and digital-to-analog conversion
• High-speed digital input/output interfaces

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 520 confirms the 5000 Vrms isolation rating and gull-wing DIP packaging. Confirm RoHS compliance status and check for any recent product change notifications that may affect pinout or material composition before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when high-speed data transmission at 50 MBd is required alongside robust noise immunity. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range for reliable performance.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-7723 series of high-speed optocouplers from Broadcom. The series utilizes CMOS technology to achieve low propagation delay and high CMTI. The HCPL-7723-520 variant specifically offers enhanced isolation voltage compared to standard 3750 Vrms models, making it suitable for demanding industrial applications.

Logic Output Optoisolators Replacement Considerations

HCPL-7723-000E: Offers similar speed but lower 3750 Vrms isolation. HCPL-7723-020E: Provides 5000 Vrms isolation but uses a different PDIP package style.
