Description
   The TCET120./ TCET2200 consists of a phototransistor optically coupled to a gallium arsenide infrared-emitting diode in a 4-lead up to 8-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.

APPLICATIONs
