Texas Instruments LVTH125 printed on the top and a quick look on the internet and I have one being sent to me, cost for this part is 67 cents. I'm not sure what the numbers in the first row are all about, I ordered a LVTH125D which is as close as I could get.
It's very small and I'm not sure how to get the old one off the board. I can't see unsoldering 14 leads at once so I thought I would clip all the leads off the part and unsolder the leads off the board one at a time.
Then I think I'll tin the 14 leads on the new part, place in position then just touch the 14 leads one at a time with my pencil iron to solder it to the board.
I'm hoping the little integrated circuit isn't too heat sensitive.
I also wonder if this part failed by it's self or if something else on the board fried it and will also fry my new part!
Really I shouldn't even attempt this but I just can't help myself.
Here's a picture of the Quadruple Buss Buffer, what ever that is. The burn hole on mine burned one of the legs off the "H" and is actually a small hole through to the inside.
