(Datasheet) ULN pdf – (ULN2xxx) Darlington Transistor Arrays (1-page)

As a driver for the motor i bought a ULN driver chip from Ebay. Or so i thought.

I might be missing something, but the chip i received has 9 pins on each side, not 8 as my sketch illustrates, ulb2804 the number on it is ULN, not ULN I’m unexperienced in how manufacturers set the numbers on the chips. How do i then change my sketch to implement the last two additional pins of the chip? Here’s the pdf for the ULN chip.

It looks like the same application and same specs, set of darlington arrays. It might’ve dataxheet a careless mistake derived from laziness since the chips have the same type of circuitries. Because these chips are practically the same, you can utilize the same way as Only in this circuit, you’d have in8out8 pins setup the same as in7 and datasheeet.

I’ve edited several other questions with this issue. JYelton Thanks for the feedback! As I am not a native speak, those rules are easily forgotten. Will try to improve now that I’m aware of it: Thanks for the response. A lot of people seem to think I’m attacking them, but I’m just interested in the quality of the site.

Thanks for your efforts! Here’s the pdf for the ULN chip It looks like the same application and same specs, set of darlington arrays. Iancovici 1, 10 So, can it work to power my stepper? And how do i alter the sketch to work with an extra pin on the chip?

This example looks fine. These chips are commonly use for this application.

You can find many tutorials online. Just not sure what i do with my driver having one more pin than the one in the toturial. I’m not experienced enough to make up my own sheet completely on my own.
