Optocoupler
11.3.1. General
Description
The TCET110. / TCET2100/ TCET4100 consist 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 lead frame using a
coplanar technique,
providing a fixed distance
between input and output for highest safety requirements.
