UDN2544 Overview
2544 QUAD DARLINGTON POWER DRIVER bining 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 prised of an opencollector Darlington driver and an internal flyback/clamp diode...
