Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute maximum ratings for extended periods of the time can adversely affect reliability.

Description

The TCET1110/ TCET1110G consists of a phototransistor optically coupled to a gallium arsenide infrared-emitting diode in a 4-pin plastic dual inline package. The elements of TCET1110/ TCET1110G are mounted on one leadframe, providing a fixed distance between input and output for highest safety requirements.
