DESCRIPTION
The SFH6345 is an optocoupler with a GaAlAs infrared
emitting diode, optically coupled to an integrated photo
detector consisting of a photo diode and a high speed
transistor in a DIP-8 plastic package. The device is similar to
the 6N135 but has an additional faraday shield on the
detector which enhances the input-output dV/dt immunity.
Signals can be transmitted between two electrically
separated circuits up to frequencies of 2 MHz. The potential
difference between the circuits to be coupled should not
exceed the maximum permissible reference voltages.
