DESCRIPTION
The SFH6943A is a four channel mini-optocoupler suitable
for high density packaged PCB application. It has a minimum
of 1768 V
consists of four phototransistors as detectors. Each channel
is individually controlled. The optocoupler is housed in a
SOT-223/10 package. All the cathodes of the input LEDs and
all the collectors of the output transistors are common
enabling a pin count reduction from 16 pins to 10 pins a
significant space savings as compared to four channels that
are electrically isolated individually.
