Fairchild Semiconductor 4N25/4N26/4N27/4N28/4N35/4N36/4N37/H11A1/H11A2/H11A3/H11A4/H11A5 Phototransistor Optocouplers Da
The document describes general purpose 6-pin phototransistor optocouplers consisting of a gallium arsenide infrared emitting diode driving a silicon phototransistor in a dual in-line package. These devices are available in black packages and white packages (specified by -M suffix). They are UL and VDE recognized and are designed for applications such as power supply regulators, digital logic inputs, and microprocessor inputs.
