The ULN2003APG/AFWG Series are high-voltage, high-current 7-channel Darlington sink drivers. These integrated circuits feature integral clamp diodes for switching inductive loads, making them suitable for applications such as relay, hammer, lamp, and LED drivers. The 'G' suffix indicates a Lead (Pb)-Free product.
