Reply to: RE>TI V.35 Line Driver Problem Randy, Sorry to hear of your trouble with your V.35.
I tested that chip (among others) fresh out of distribution in March 1995. No problems to NET 2 were found. I cannot confirm the acutal date of manufacture. I wish you well in your investigation.

What we have seen are that parts made since 1994 fail the output differential voltage requirement in NET2/CTR2 because of thermal sensitivity. The high limit is 660mv and we are getting 720+ once the devices warm up on their own accord. Pre-1994 devices do not exhibit the same problem. Any information would be appreciate. TI is noncommittal at this point.
