The HD74LV2GT125AUS doesn't match the pin-out unfortunately, but a 74LVC2G38 does match and is probably the part.

As it turns out, the failure was in another chip just upstream of of it. A teensy tiny 8-pin + GND chip about the size of a grain of sand. Turned out to be a 4ch ESD protection device, which makes sense -- it failed and protected the rest!

Thanks all!
