All About IC ULN2003

PCBway: only $5 for 10 pcbs from https://www.pcbway.com/?from=CZcouple The ULN2003 IC contains 7 High Voltage, High Current NPN Darlington Transistor Arrays each rated at 50V, 500mA in a 16-pin DIP package. You can connect the IC directly to a digital logic (like Arduino or Raspberry Pi, TTL or 5V CMOS device) without an external dropping resistor. This IC features "common-cathode flyback diodes" for switching inductive loads. The ULN2003 is known for its high current and high voltage capacity. The Darlington pairs can be "paralleled" for higher current Output. The inputs are capable with TTL and 5v CMOS logic. Now, let's deep-dive and check out the internals of the IC and how it can be used in our projects. Thanks ------ Thanks again for checking my post. I hope it helps you.
