VISHAY SFH6343T

The SFH6343T is a 1-channel 8-pin high speed Transistor Output Optocoupler consists of a GaAlAs infrared emitting diode, optically coupled with an integrated photodetector and a high speed transistor. The photodetector 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 and CMOS. It has a faraday shield on the detector chip, it can also reject and minimize high input to output common-mode transient voltages. There is no base connection, further reducing the potential electrical noise entering the package. It is suitable for line receivers, logic ground isolation, analogue signal ground isolation and replace pulse transformers.
