HCPL-623K

Logic Output Optoisolators Overview

The HCPL-623K is a high-speed optocoupler manufactured by Broadcom Limited, housed in a hermetically sealed LCCC-20 package. It features two independent channels with a data rate of 5 Mb/s and an isolation voltage of 1500 Vrms. The device utilizes open collector outputs, supporting a forward current of 8 mA and a forward voltage of 1.3 V. Key timing parameters include a rise time of 45 ns and a fall time of 10 ns. It operates within a temperature range of -55°C to +125°C, dissipating up to 200 mW.

Logic Output Optoisolators Feature Summary

• Hermetically sealed construction for enhanced environmental stability
• High common mode transient immunity capability
• Logic output configuration for digital signal transmission

Logic Output Optoisolators Applications

• Space-qualified electronic systems requiring radiation resistance
• High-speed digital communication interfaces demanding optical isolation
• Industrial control systems operating in extreme temperature environments

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'K' indicates space qualification status against official datasheets. Confirm package dimensions match the LCCC-20 specification. Ensure compliance with required environmental certifications for the target application before procurement.

Logic Output Optoisolators Selection Notes

Select this component when hermetic sealing and wide temperature operation are mandatory. Compare rise and fall times against system bandwidth requirements. Verify that the open collector output type aligns with the downstream logic circuit design constraints.

Logic Output Optoisolators Part Context

This part belongs to the HCPL series of high-speed optocouplers from Broadcom. It shares architectural similarities with other models in the family but is distinguished by its hermetic packaging and specific speed characteristics suitable for demanding applications.

Logic Output Optoisolators Replacement Considerations

HCPL-6231 is a non-hermetic alternative within the same series. Verify if hermetic sealing is strictly required; otherwise, check pin compatibility and electrical parameter alignment.
