are all the vendors they list U.S.-only? What does that mean? Do you mean that they only ship to U.S. destinations? I doubt that. Isn't Farnell a division of Newark? (Maybe it's not Farnell, but Newark did, at one time have a U.K. subsidiary/partner.) I agree Newark is often a bit ridiculous with pricing, and often waits for the day it's supposed to arrive before shipping your order, but they're not alone in that, by any means.

I just took a look and found this for 74HCT193

This isn't nicely formatted, as it's just copied from a web page. However, at least a couple aren't U.S. vendors.
