I’m unexperienced in how manufacturers set the numbers on the chips. Please capitalize “I” when referring to yourself. Sign up or log in Sign up using Google.

I might be missing something, but the chip i received has 9 pins on each side, not 8 as my sketch illustrates, and the number on it is ULN, not ULN It looks like the same application and same specs, set of darlington arrays. This example looks fine.
ULN Datasheet PDF –
These chips are commonly use for this application. Thanks for your efforts! It might’ve been a careless mistake derived from laziness since the datasheeet have the same type of circuitries.
Here’s the pdf for the ULN chip. I’ve edited several other questions with this issue. How do i then change my sketch to implement the last two additional pins dqtasheet the chip? Will try to improve now that I’m aware of it: I have an unipolar stepper motor that im driving with an Arduino.

(Datasheet) ULN pdf – (ULN2xxx) Darlington Transistor Arrays (1-page)
So, can it work to power my stepper? As a driver for the motor i bought a ULN driver chip from Ebay. Just not sure what i do with my driver having datashheet more pin than the one in the toturial. JYelton Thanks for the feedback! Or so i thought.

You can find many tutorials online. And how do uon2804 alter the sketch to work with an extra pin on the chip? As I am not a native speak, those rules are easily forgotten.
Only in this circuit, you’d have datasueetout8 pins setup the same as in7 and out7.
