DESCRIPTION

The SFH6315, SFH6316, SFH6343, high speed

optocouplers, each 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 SFH6343 has a faraday shield on the detector

chip, it can also reject and minimize high input to output

common mode transient voltages. The SFH6343 provides

an isolated base connection to further reduce the potential

electrical noise entering the package.
