Description

The SFH6943A is a four channel mini-optocoupler

suitable for high density packaged PCB application. It

output. The device 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 collec-

tors of the output transistors are common enabling a

pin count reduction from 16 pins to 10 pins-a signifi-

cant space savings as compared to four channels that

are electrically isolated individually.
