IEC (pending approval) Applications Microprocessor system interface SPI, I C Industrial fieldbus communications DeviceNet, CAN, RS485 Programmable logic control Isolated data acquisition system Voltage level translator Isolating MOSFET/IGBT gate drivers Functional Schematic ANODE V CC 5 V O Description May The FODM8 is a 3.3V/5V high-speed logic gate output (open collector) optocoupler, which supports isolated communications allowing digital signals to communicate between systems without conducting ground loops or hazardous voltages. It utilizes Fairchild s patented coplanar packaging technology, Optoplanar, and optimized IC design to achieve high noise immunity, characterized by high common mode transient immunity specifications. This optocoupler consists of an AlGaAS LED at the input, optically coupled to a high speed integrated photodetector logic gate. The output of the detector IC is an open collector schottky-clamped transistor. The coupled parameters are guaranteed over the wide temperature range of -4 C to + C. A maximum input signal of 5mA will provide a minimum output sink current of 3mA (fan out of 8).

3 Absolute Maximum Ratings (T A =5ºC unless otherwise specified) Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.

Common mode transient immunity at output high is the maximum tolerable positive dvcm/dt on the leading edge of the common mode impulse signal, Vcm, to assure that the output will remain high. Common mode transient immunity at output low is the maximum tolerable negative dvcm/dt on the trailing edge of the common pulse signal, Vcm, to assure that the output will remain low. 9 Fairchild Semiconductor Corporation FODM8 Rev FODM8 High Noise Immunity, 3.3V/5V, Mbit/sec Logic Gate Output (Open Collector) Optocoupler
