Data Sheet 29317D 2540 QUAD DARLINGTON POWER DRIVER UDN2540B (DIP) Combining AND logic gates and inverting high-current bipolar outputs, the UDN2540B and A2540SLB quad Darlington power drivers provide interface between low-level signal-processing circuits and power loads totaling 360 W. Each of the four independent outputs can OUT4 1 K2 T OUT3 3 C GROUND 4 U GROUND 5 D OUT2 6 O LY K 7 D PRCE ON OUT1 8 16 IN4 15 IN3 14 ENABLE 13 GROUND 12 GROUND 11 V CC 10 IN 2 9 IN 1 Dwg. PP-017-2 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 open-collector Darlington driver and an internal flyback/clamp diode for switching inductive leads. They feature a minimum breakdown and sustaining voltage of 50 V.
