I think that the 8740 offers a slow roll-off, but not the minimum-phase features. I am unaware of any commercial product that touts minimum-phase filters aside from ours and the recently released Meridian 808 MkII Signature CD player.
The Burr-Brown DF1704 was the first commercially available chip that I know about that used slow roll-off algorithms. We used that in our D-1 DVD player starting in 1999. (Wadia was the first complete DAC, available in 1989 or so.)
