Description

The K814P/ K824P/ K844P consist of a phototransistor optically coupled to 2 gallium arsenide infrared-emitting diodes (reversed polarity) in an 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.
