ACPL-244-560E – AVAGO

The ACPL-244-560E is a quad-channel optocoupler manufactured by Avago Technologies, housed in a 16-pin small outline (SO) package. Each channel incorporates an AlGaAs LED optically coupled to a silicon phototransistor, providing 3 kVrms of reinforced insulation per EN/IEC 60747-5-5. The device exhibits a current transfer ratio (CTR) within the 50-300% range at an input current of 5mA, suitable for isolating logic signals and preventing ground loops. Key electrical characteristics include a typical forward voltage of 1.4V and a collector-emitter breakdown voltage exceeding 7V. Propagation delay times are typically in the microsecond range, dependent on operating conditions. The ACPL-244-560E is designed for operating temperatures ranging from -40°C to +85°C, making it suitable for industrial control, data communication, and power supply applications requiring galvanic isolation.
