Replacement diff bus xcvr?
The part that has failed has these markings:
LS1176 8AT D5HT This is the data sheet for it, I think: SN65ALS1176: www.cgi/http://www.allcomponents.ru/pdf/ti/sn65als1176.pdf although how to I tell if the failed one is a 65 or 76 prefix part? Searching local suppliers, I find this: SN75LBC176A: http://www.jameco.com/Jameco/Products/ProdDS/251053TI.pdf 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, -- John English |
