Description
The SFH6325/6326 are dual channel optocouplers
with a GaAIAs infrared emitting diode, optically
coupled with an integrated photodetector which
consists of a photodiode and a high-speed transis-
tor in a DIP-8 plastic package.
Signals can be transmitted between two electrically
separated circuits up to frequencies of 2.0 MHz.
The potential difference between the circuits to be
coupled is not allowed to exceed the maximum per-
missible reference voltages.
