Vishay, SFH6343T Phototransistor Output Optocoupler, Surface Mount, 8-Pin SOIC

The Vishay High speed Optocoupler consists of a GaAlAs infrared emitting diode, optically coupled with an integrated photo detector and a high speed transistor. The photo detector is junction isolated from the transistor to reduce miller capacitance effects. The open collector output function allows circuit designers to adjust the load conditions when interfacing with different logic systems such as TTL, CMOS, etc. Because the it has a faraday shield on the detector chip, it can also reject and minimize high input to output common mode transient voltages. It provides an isolated base connection to further reduce the potential electrical noise entering the package.
