Go with OPTO Protect with Broadcom Optocouplers [View Optocoupler Green eBook](https://docs.broadcom.com/docs/going-green-optocouplers) ## Broadcom Optocouplers ### 50 Years of Proven High Voltage Protection and Signal Isolation ![Go with OPTO!](https://www.broadcom.com/media/blt4ac44e0e6c6d8341/blt197724b9fb24993e/606c3a2eebebdb213c89a464/go-with-opto-border-50-years.png) With roots tracing back more than 50 years to Hewlett-Packard and Avago Technologies, Broadcom is a leading provider of galvanic isolation products for industrial and automotive markets leveraging its field-proven, time-tested optocoupler technology. Broadcom’s opto-isolation solutions provide unmatched high voltage protection and signal isolation that meet or exceed international safety standards. Broadcom optocouplers, including digital optocouplers, isolation amplifiers and gate drive optocouplers, are used in a broad array of applications ranging from power supply and motor control circuits to data communication and digital logic interfaces. ## Key Benefits - Unmatched Galvanic Isolation Technology - Proven High Voltage Protection - Superior Noise / Transient Suppression ## OPTO vs non-OPTO ![OPTO vs. NON-OPTO](https://www.broadcom.com/media/blt4ac44e0e6c6d8341/blt603734c026e12530/606c3ad441a2fd66d84185ba/main-graphic-sized.jpg) ### Alternative Galvanic Isolation Technologies are a No-No! Only optocouplers meet or exceed international safety standards for insulation and isolation. Stringent evaluation tests show Broadcom optocouplers deliver outstanding safety performance and exceptional high voltage protection. Alternative galvanic isolation technologies such as capacitive and magnetic isolators do not perform anywhere near the levels of insulation and isolation provided by Broadcom optocouplers.
