L293D on Digi-Key

logan996

Hi guys i want one of those PWM H-bridges and ive heard the L293D is a easy one to use, so i went onto digi-key to search for the chip for cheap and well i can't find the normal DIP one! i just want a regular L293D for 2 motors i have but they have all these weird versions and stuff! Can anyone help? SEARCH RESULTS: http://search.digikey.com/scripts/DkSearch/dksus.dll?lang=en&site=US&WT.z_homepage_link=hp_go_button&KeyWords=L293D&x=37&y=27 P.S. noticed some came with built in diodes, should i get one of those?

I'm not sure what the problem is. They show more than 6000 of the L293D (DIP) in stock.

I was working on my PropCade BOM, so I had the Digikey web site open.

Here you go:

296-9518-5-ND
296-9519-5-ND
497-1389-5-ND
497-2936-5-ND

Why not just go to Parallax?

Cheaper than the DigiKey part Phil quoted.

You may also want to consider the TI SN754410 chip which is a drop in replacement for the L293D chip. The TI chip can handle a little more current (1amp) and if needed you can stack two of them to get a little more capacity.

2nd that. I have replaced all my L293D's with SN754410.
