Optocoupler with Photodarlington Output
Description
The TCED1 100/ TCED2100/ TCED4100 consists of
a phototransistor optically coupled to a gallium arsenide infrared-emitting diode in a 4-lead up to 16-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.
