DESCRIPTION The general purpose optocouplers consist of a gallium arsenide infrared emitting diode driving a silicon phototransistor in a 6-pin dual in-line package.
FEATURES • Also available in white package by specifying -M suffix, eg. 4N25-M • UL recognized (File # E90700) • VDE recognized (File # 94766) - Add option V for white package (e.g., 4N25V-M) - Add option 300 for black package (e.g., 4N25.300)
APPLICATIONS • Power supply regulators • Digital logic inputs • Microprocessor inputs
