Heatsink for stacked Output Driver Chips (SN754410NE)

Posted by Eirik Simonsen at March 17. 2008

Hi,

I'm looking for heatsinks that fit stacked SN754410NE chips.

Acroname.com has a picture of a nice variant, but they don't sell them.

Check here: http://www.acroname.com/robotics/info/ideas/stacking/stacking.html#c

Does anyone have a clue where I can get these on the web?

Best regards

EirikS

Yes! I have found the name of these heat sinks - Dip Heat Sinks. Technically 14-16 Dip Heat Sink. Kronos Robotics has them for 99¢, and they are perfect for the TI SN75441ONE Quad half H-bridges on the Make Application board! They even have a web page that shows how to stack two SN75441 chips together with attached Dip Heat Sink! Jonathan

Jonathan - cool, thanks for posting this. I'll add a link from an appropriate spot in the Application Board guide.

Hi Jonathan, well done!

I live in Norway and Kronos Robotics only ship to US/Canada.

A search for Dip Heat Sinks revealed that DigiKey also have them in stock.
