All devices are pinned with outputs opposite inputs to facilitate ease of circuit board layout. It might’ve been a careless mistake derived from laziness since the chips have the same type of circuitries. These devices will handle numerous interface needs particularly those beyond the capabilities of standard logic buffers. Characteristic shown applies to family of devices with remaining digits as shown. Details, datasheet, quote on part number: Typical loads include ulln2804, solenoids, stepping motors, magnetic print hammers, multiplexed LED and incandescent displays, and heaters.

I’m not experienced enough to make up my own sheet completely on my own. As I am not a native speak, those rules are easily forgotten. As a iln2804 for the motor i bought a ULN driver chip from Ebay.

ULN datasheet – Octal High Voltage, High Current Darlington Transistor

JYelton Thanks for the feedback! Thanks for your efforts! High Voltage 3 Phase Motor Drivers The SCMM series IPM Inverter Power Module device provides a robust, highly-integrated solution for optimally controlling 3-phase motor power inverter systems and variable speed control systems used in energy-conserving designs to drive motors of residential.

Iancovici 1, 10 The outputs are capable of sinking mA and will withstand at least V in the off state. These chips are commonly use for this application. Just not sure what i do with my driver having one more pin than the one in the toturial. I’m unexperienced in how manufacturers set the numbers on the chips.

This example looks fine. It looks like the same application and same specs, set of darlington arrays. You can find many tutorials online. Specification shown applies to family of devices with iln2804 digits as shown.

Or so i thought. Please capitalize “I” when referring to yourself. Post as a guest Name. Because these chips are practically the same, you can utilize the same way as Thanks for the response.

Uln280 the pdf for the ULN chip. Note that the ULx28xxA series dual in-line package and ULx28xxLW series smalloutline IC package are electrically identical and share a common terminal number assignment. Complete part number includes prefix to operating temperature range: Will try to improve now that I’m aware of it: I’ve edited several other questions with this issue.

So, can it work to power my stepper? And how do i alter the sketch to work with an extra pin on the chip?

Here’s the pdf for the ULN chip It looks like the same application and same specs, set of darlington arrays. 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 A lot of people seem to think I’m attacking them, but I’m just interested in the quality of the site. Only in this circuit, you’d have in8out8 pins setup the same as in7 and out7.
