Description
The SFH674xT and SFH675xT are single and dual
channel 10 MBd optocouplers utilizing a high efficient
input LED coupled with an integrated optical photo-
diode IC detector. The detector has an open drain
NMOS-transister output, providing less leakage com-
pared to an open collector Schottky clamped transis-
ter output. For the single channel type, an enable
function on pin 7 allows the detector to be strobed.
The internal shield provides a guaranteed common
mode transient immunity of 5 kV/µs for the SFH6746T
and SFH6756T and 10 kV/µs for the SFH6747T and
SFH6757T. The use of a 0.1 µF bypass capacitor
connected between pin 5 and 8 is recommended.
