The part that has failed has these markings:
LS1176 8AT D5HT
This is the data sheet for it, I think:
SN65ALS1176:
although how to I tell if the failed one is a 65 or 76 prefix part?
Searching local suppliers, I find this:
SN75LBC176A:
Is the second a suitable replacement for the first?
Package is SOIC.
They're both TI, so why the different numbering (1176 vs 176)? What does
65/75 prefix indicate? And regarding the other markings on the failed IC: does HT mean Hi-Temp?A few too many discrepancies in my mind to just swap it in just yet.
Thanks,
