ULN2083 - What are the alternatives? - Electronic Circuits Projects Diagrams Free

tim_l_012 · 23rd May 2003, 02:34 PM

Hello to all readers,

I have been looking at this fan monitoring article:
http://www.pc-workshop.net/articles/...mmonitor.shtml

And I want to know what are the alternatives to the IC that the author uses. The IC is the ULN2803 from Jameco, but I couldn't find it anywhere.

He describes it as a 18-pin IC, but I am not sure if I can use any 18-pin IC or not.

If someone could help me out here it would be very helpful.

Thanks in advance,

ULN2803 is 8-transistor current sink driver. Here in the circuit only 1 out of 8 transistor is used so you can use any other sink drivers like ULN2003 which are 7-transistor sink drivers and is easily available.

OK, Well the place I would be buying it from would be Dick Smith electronics in Australia.

I have had a look at the online product listing, and i have foun a 7 Way Darlington Driver. I did a search for ULN and thats what I got.

Could I use that?
