UDN2544 QUAD DARLINGTON POWER DRIVER

2544 QUAD DARLINGTON POWER DRIVER Combining logic gates and high-current bipolar outputs, the UDN2544B quad Darlington power driver provides an interface between low-level logic circuitry and high-power loads. Each of the four outputs can sink up to 1.8 A in the on state with peak inrush currents to 2.5 A. The four power outputs are each comprised of an ope.
