Description

High Speed Optocoupler, SFH6345, 1 Mbd, 15 kV/µs CMR, Transistor Output,

The SFH6345 is an optocoupler with a GaAlAs infrared emitting diode, optically coupled to an integrated photodetector consisting of a photodiode and a high speed transistor in a DIP-8 plastic package. The SFH6345 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 SFH6345 difference between the circuits to be coupled should not exceed the maximum permissible reference voltages.
