ULN2003
Darlington transistor array
Product features:
ULN2003 is a 7-way Darlington structure circuit.
The output current of each channel is 500mA, the peak current is 600mA, and the output voltage is 50V.
Emitter structure, each channel can be output independently. Should Circuits are often used to drive various loads, such as DC motors, LED display lights, high-power buffers and 5V TTL, CMOS and other general logic circuits, etc.
