HCPL-7721#360

Logic Output Optoisolators Overview

The HCPL-7721#360 is a high-speed optocoupler featuring a single channel with a data rate of 25 MBd. It provides an isolation voltage of 3750 Vrms and operates within a temperature range of -40°C to 85°C. The device utilizes a push-pull output type capable of sourcing or sinking 10 mA. Typical rise and fall times are 9 ns and 8 ns, respectively, with a maximum propagation delay of 40 ns. It offers a minimum common mode transient immunity of 10 kV/µs.

Logic Output Optoisolators Feature Summary

• High-speed digital transmission capability supporting up to 25 MBd data rates for efficient signal isolation.
• Robust noise immunity characterized by a minimum common mode transient rejection of 10 kV/µs.
• Direct compatibility with 5 V CMOS logic families, simplifying interface design without additional level shifting.

Logic Output Optoisolators Applications

• Isolation for industrial digital fieldbus networks such as CC-Link, DeviceNet, and PROFIBUS.
• Microprocessor system interfaces requiring high-speed data transfer between isolated domains.
• General-purpose digital communication links in noisy industrial environments.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix #360 against official Broadcom documentation to confirm package configuration and tape-and-reel specifications. Ensure compliance with RoHS directives if required by your application standards. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability and authenticity before procurement.

Logic Output Optoisolators Selection Notes

Select this component when high-speed isolation exceeding standard optocoupler limits is required. The 25 MBd rate suits applications needing rapid data exchange. Verify that the 3750 Vrms isolation rating meets safety standards for your specific circuit voltage levels. Confirm that the 10 mA output current is sufficient for driving downstream logic inputs directly.

Logic Output Optoisolators Part Context

This device belongs to the HCPL series of high-speed optocouplers manufactured by Broadcom Limited. The series is designed for demanding digital isolation applications where speed and noise immunity are critical. The HCPL-7721 variant specifically targets interfaces requiring fast response times and robust performance in electrically noisy environments.

Logic Output Optoisolators Replacement Considerations

Check for direct pin-compatible alternatives within the HCPL family, such as the HCPL-7723, which may offer similar electrical characteristics. Verify that any substitute maintains the same 25 MBd data rate and 3750 Vrms isolation voltage to ensure functional equivalence in existing designs.
