I don't know which IC to pick between sn754410 or L293D; I need a Half- Bridge Driver for my stepper because it's a bipolar. Those IC's are both made by Texas Instrument. There is a huge price difference (digikey) and they are almost the same, I can't seem to identify the difference expect that the L293D have an internal diodes and the sn754410 doesn't. And I looked on line for difference and I couldn't find any proper explanation

So which one do you think I should go for? I was going for the L293D but now I am not sure anymore because I need 3 of those!
Thanks you
