DESCRIPTION
The SFH6943 is a four channel mini-optocoupler
suitable for high density packaged PCB applica-
tion. It has a minimum of 1768 VRMS isolation from
input to output. The device consists of four pho-
totransistors as detectors. Each channel is indi-
vidually controlled. The optocoupler is housed in
a SOT223/10 package. All the cathodes of the
input LEDs and all the collectors of the output
transistors are commoned enabling a pin count
reduction from 16 pins to 10 pinsâa signiï¬cant
space savings as compared to four channels that
are electrically isolated individually.
