Fried component U19 - Replacement viability?

[griffinboyle]

Hello,

Yesterday I made the unfortunate mistake of wiping an aluminum chip off of a desk surface, after which it proceeded to land directly on the Kogna and release a plume of magic smoke (I think near JP4/JP6, but I only discovered the aluminum chip after unmounting the damaged board so it may well have moved from the original problem location). Closer inspection seems to reveal that U19 was the only damaged component, so I figured it might be worth a try swapping in a new part.

Thus my question is two-fold: What is the part number for component U19, and are there any upstream/downstream systems which may also have been damaged while/after U19 fried?

Thanks,
Griffin Boyle

Hi Griffin,

Sorry to hear that. U19 is a SN74LVC1G11DBVR 3 input AND gate having to do with resets so unfortunately connects to a few devices including the DSP and Ethernet Transceiver.

Good luck.
