SFH6345 Datasheet Analog High Speed Coupler

Manufacturer: Vishay

General 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.
