TCDT1100(G) Series
Vishay Telefunken
Optocoupler with Phototransistor Output
Description
The TCDT1100(G) series 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.
