Shown on this slide are some of the advantages and benefits of both the XR20M1280 and the XR16M890. The integrated voltage level shifters make these devices an ideal fit in applications that have multiple voltage rails and where data needs to flow from one device that operates at one particular voltage level to another device that operates at another voltage level. Zero nanosecond address setup/hold time, different Tx/Rx data rates, 4x/8x sampling options  and fractional baud rate generator make design with these parts much simpler, more flexible and more cost efficient. Hardware and software flow control prevent data loss and the auto RS-485 half-duplex control feature simplifies both the hardware and software development of RS-485 applications.
