The TLP290-4(GB-TP,E(T with Optocouplers SO-16 RoHS is a photocoupler manufactured by Toshiba. It is a phototransistor output optocoupler that offers a wide range of features including high isolation voltage, small size, high horizontal/vertical CMRR, low input/output thermal drift, fast response, and low forward current. The SO-16 package is also particularly suited for applications requiring extra safety and protection requirements as it complies with the new RoHS directive. It is typically used as part of a signal isolation system and is also suitable for UART data communication interfaces, digital-to-analog converters, motor control applications, and bidirectional motor drives.
