2540 General Description

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 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. The logic inputs are compatible with TTL and 5 V CMOS logic systems.

Typical applications include print heads, relays, solenoids, and dc stepping motors. These drivers can also be used to drive highcurrent incandescent lamps, LEDS, and heaters. A similar device, specifically intended for driving a unipolar stepper motor in the two-phase drive format, is the UDN2544B.

The UDN2540B is supplied in a 16-pin batwing power DIP; the A2540SLB is supplied in a 20-lead batwing power SOIC for surfacemount applications. The batwing construction provides for maximum package power dissipation in a standard construction. At 25°C, and with only 1 sq. in. of copper foil at the ground tabs, either package is capable of safely dissipating more than 2 W.
