When doing a part comparison on the website I get the following totally useless results:

  TUSB320LI TUSB320HI TUSB320LAI TUSB320HAI TUSB320

I could spend an unknown amount of time figuring this out but I thought I would ask here first.

    My take-away from this is: A vs. Non A = Supply current and ESD - H vs. L = Enable signal sense.

    Thanks for getting back so quickly.
