K817P/ K827PH/ K847PH
Vishay Telefunken
Optocoupler with Phototransistor Output
Description
The K817P/ K827PH/ K847PH consist of a photo-
transistor optically coupled to a gallium arsenide
infrared-emitting diode 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.
Applications
Programmable logic controllers, modems, answering
machines, general applications
