The MAX3222EIDBR: The 2/2 driver/receiver count gives you two full RS-232 channels in one package, enough for a basic DTE-to-DCE link or a two-port interface on a single PCB. The 500 kbps data rate is fast enough for most industrial UART applications (115200 baud is typical), but if you need higher throughput, you will be looking at a different transceiver family. Receiver hysteresis of 300 mV provides noise immunity on the incoming serial lines, which matters in electrically noisy environments like motor drives or relay panels.
