These optocouplers consist of an AlGaAS LED, optically coupled to a very high speed integrated photo-detector logic gate. Single channel devices include a strobable output. This output features an open collector, thereby permitting wired OR outputs. The output consists of bipolar transistors in a Bi-CMOS process for reduced power consumption. The coupled parameters are guaranteed over the temperature range of -40°C to +85°C. A maximum input signal of 5 mA (3 mA for the FODX6XL versions) will provide a minimum output sink current of 13 mA (fan out of 8). An internal noise shield provides superior common mode rejection of typically 50 kV/s at 2,000V common mode.
