HCPL-4661-300E

Logic Output Optoisolators Overview

The HCPL-4661-300E is a dual-channel high-speed optocoupler from Broadcom Limited, housed in an 8-pin PDIP Gull Wing surface-mount package. It features a GaAsP LED coupled to an integrated high-gain photodetector with open collector outputs. Key electrical parameters include a data rate of 10 Mb/s, isolation voltage of 3750 Vrms, and common-mode transient immunity of 15 kV/µs. The device operates with a forward current of 10 mA, typical rise time of 24 ns, and fall time of 10 ns. It supports a maximum output current of 50 mA and functions within a temperature range of -40°C to +85°C.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '300E' corresponds to the tape-and-reel packaging format rather than tube packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or certified distributor declarations prior to final procurement decisions. Ensure the component matches the required surface-mount mounting style for the target PCB design.

Logic Output Optoisolators Selection Notes

Select this component for applications requiring high-speed digital isolation between circuits with significant noise environments. The dual-channel configuration allows for isolated transmission of multiple signals within a single compact package. Consider the 3750 Vrms isolation rating for safety-critical interfaces and verify that the 10 Mb/s data rate meets the system's timing requirements.

Logic Output Optoisolators Part Context

This part belongs to the HCPL series of high-speed optocouplers manufactured by Broadcom Limited. The series is designed for demanding industrial and automotive applications where reliable signal transmission across isolation barriers is critical. The HCPL-4661 specifically addresses the need for fast response times and high noise immunity in compact surface-mount formats.

Logic Output Optoisolators Replacement Considerations

Direct replacement options may include other dual-channel high-speed optocouplers from Broadcom such as the HCPL-4661-000E, though packaging differences must be verified. Cross-manufacturer replacements require careful evaluation of pinout compatibility, isolation voltage ratings, and propagation delay specifications to ensure circuit functionality remains intact.
