(Manufactured by Toshiba Malaysia)

8ch Darlington Sink Driver

The ULN2803APG / AFWG Series are high−voltage,
high−current darlington drivers comprised of eight NPN
darlington pairs.
All units feature integral clamp diodes for switching inductive
loads.
Applications include relay, hammer, lamp and display (LED)
drivers.
The suffix (G) appended to the part number represents a Lead
(Pb)-Free product.
