Frequently asked questions
What is the price of ULN2003 SMD Darlington Transistor Array IC in Egypt?
ULN2003 SMD Darlington Transistor Array IC currently costs 10 EGP in Egypt.
Where can I buy ULN2003 SMD Darlington Transistor Array IC in Egypt?
ULN2003 SMD Darlington Transistor Array IC is available from RAM Electronics. Compare the offers above to find the best price.
Can I drive a stepper motor directly from microcontroller pins using the ULN2003?
Yes. Each input is driven from a microcontroller pin and each output drives one motor coil, with the motor's common line connected to the motor supply. Keep the motor supply within the 50 V output rating and each channel below 500 mA.
Does the ULN2003 need a separate power supply and a common ground?
The output side is powered by the load supply, so the ULN2003 needs its load supply connected to its common line. The ground of the microcontroller and the ground of the load supply must be connected together to share a common reference.
