Well, it's official. The ACT244's certainly seem to degrade in normal use. I don't think I put unusual stress on this TIU, but here's the Variable #1 channel before and after the replacement of the ACT244 chip at U340. So, it doesn't take the errant TVS to kill them, they can die all on their own.

GREAT! What is the Digikey number for the chip.

Here is a search for appropriate parts with small quantity ordering.

Digikey 74ACT244DW Parts

Naturally, I pick the cheapest one if I can.
