  • Entirely different manufacturing process
  • reduction in the supply voltage from 22V to 18V
  • halving of the ESD protection from 2kV to 1kV

My guess is the old part was getting expensive to manufacture, so they jewed the part.

A friend of mine who works in government contracting says this could cause some real issues for them. The government specifies something and expects it to be the same forever and ever, amen...and if you're using the same "number" but it no longer works, then it's a complete pain to qualify something else.

That's not even getting into the semantics of how the old part is now "new" because the die is completely different and it's essentially something so removed from the original that you may have to requalify it too.

From my point of view, you're correct: it's not the same part. It may be pin compatible, but certainly not behaviorally compatible. Static discharge is a huge problem now, the power rails are no longer the same, so it will fail. The slew rate... I don't even know where to go with that, that will break shit. Oh! The inputs are no longer compatible. It's a different bird.
