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.
