Fairchild High Noise Immunity
Logic Gate Output OptocouplerFairchild's High Noise Immunity Logic Gate Output Optocouplers are high-speed logic gate output (open collector) optocouplers that support isolated communications allowing digital signals to communicate between systems without conducting ground loops or hazardous voltages. These High Noise Immunity Logic Gate Output Optocouplers utilize Fairchild's proprietary coplanar packaging technology, Optoplanar®, and optimized IC design to achieve high noise immunity, characterized by high common mode transient immunity specifications. Applications for these High Noise Immunity Logic Gate Output Optocouplers include microprocessor system interface (SPI, I2C), industrial fieldbus communications (DeviceNet, CAN, RS485), programmable logic control, isolated data acquisition system, and voltage level translator.
