What chip in the USB serial Converter USB RS-485?

Good day, comrades! Decided at leisure to play with the automation and the first thing that came to mind, for the connection of several individual devices with the computer is the interface Converter USB RS-485. Usually, they are based on two chips:
1. Converter USB to TTL
2. Converter TTL to RS-485

As the first 95% of the cases use a FT232, but in what store did not ask, everywhere one answer that they have not brought. As a second MAX485, too rare beast to order via the Internet do not want to, and the soul does not warm the fact that they have not sell are old so..
But before I begin, I want to know the modern circuits of both converters?
