Description
The SFH6943A is a four channel mini-optocoupler suitable for high density packaged PCB application. It has a minimum of 1768 VRMS isolation from input to output. The device consists of four photo
transistors 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.
Applications
Telecommunication SMT PCMCIA Instrumentation
