Optocoupler with Phototransistor Output
Description
The TCDT1110(G) consists of a phototransistor optically coupled to a gallium arsenide infrared emitting diode in a 6-lead plastic dual inline package. The elements are mounted on one leadframe using a coplanar technique, providing a fixed distance between input and output for highest safety requirements.
