Description

The FOD8001 is a 3.3V/5V high-speed logic gate Optocoupler, which supports isolated communications allowing digital signals to communicate between systems without conducting ground loops or hazardous voltages. It utilizes Fairchild’s proprietarycoplanar packaging technology, Optoplanar®, and optimized IC design toachieve high noise immunity, characterized by high common mode rejection and power supply rejection specifications.
