HCPL-0721-500E

Logic Output Optoisolators Overview

The HCPL-0721-500E is a high-speed optocoupler from the Broadcom HCPL series, featuring a single channel with a data rate of 25 Mb/s. It utilizes an open collector output type and supports a forward current of 10 mA with a typical forward voltage of 5 V. The device offers an insulation voltage of 3750 Vrms and operates within a temperature range of -40°C to +85°C. Key timing parameters include a rise time of 9 ns, a fall time of 8 ns, and a propagation delay of 40 ns. It is housed in an SOIC-8 surface-mount package with a power dissipation rating of 150 mW.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '500E' corresponds to the tape-and-reel packaging configuration, as other suffixes like '000E' indicate tube packaging. Confirm that the open-collector output specification aligns with the target circuit design requirements. Ensure compliance with RoHS directives and relevant safety certifications such as UL, IEC, EN, and CSA before final procurement decisions.

Logic Output Optoisolators Selection Notes

Select this component when a single-channel high-speed interface with 25 Mb/s data throughput is required. The SOIC-8 package suits surface-mount assembly processes. Consider the 10 mA output current capability and open-collector nature for pull-up resistor selection. Verify that the 3750 Vrms isolation voltage meets the system's safety isolation barriers.

Logic Output Optoisolators Part Context

This part belongs to the Broadcom HCPL series of high-speed optocouplers. It shares core electrical characteristics with variants like HCPL-0721-000E and HCPL-0720-500E, differing primarily in packaging format. The series is designed for robust signal transmission across isolated boundaries in industrial and automotive environments.

Logic Output Optoisolators Replacement Considerations

HCPL-0721-000E serves as a functional substitute with identical electrical specifications but differs in packaging (tube vs. reel). HCPL-0720-500E offers similar speed and isolation but features a Photo IC output instead of open collector.
