Aren't FTDI chips TTL? Such as the one and the arduino Duemilanove?
I think you would be hard pressed to find any mass produced IC developed in the last 10 years (perhaps even longer) that is bipolar (as pure TTL is based on) tech, rather then the various CMOS derived tech. Once they got the speed and output drive to be competitive with bipolar TTL, the other overwhelming features of CMOS made it the mainstream tech to use in IC development. I think newer bipolar IC designs are probably only used in few low volume specialized niche applications, it at all?
