DESCRIPTION
The SFH6345 is an optocoupler with a GaAlAs infrared
emitting diode, optically coupled to an integrated photode-
tector consisting of a photodiode and a high speed transis-
tor 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 sepa-
rated circuits up to frequencies of 2 MHz. The potential dif-
ference between the circuits to be coupled should not
exceed the maximum permissible reference voltages.
