TCD1102:
16.10.1.
Description
The TCET110./ TCET2100/ TCET4100 consists of a phototransistor optically coupled to a gallium
arsenide infrared emitting diode in a 4-lead plastic dual inline package. The elements are mounted on
one leadframe using a
coplanar technique , providing a fixed distances between input and output for highest safety
requirements.
