Is one or the other of the AM79R79 or AM79R70 SLICs intended to be a
replacement for the other? And if so, which is newer? The data sheets
for the AM79R79 all appear to be older. (Is there an even newer replacement?)
I'm thinking of trying to repair some Motorola Bitsurfr ISDN TAs and the SLIC
chips are often the (obvious) problem. Back when they were under warranty it
seemed that Motorola would use the R79 as a replacement for the R70 but it
might just have been a stocking coincidence. On the off chance that anyone
is interested I have some vague theories about why the SLIC chips get
damaged...
