Additional Details:

The SP3222EBCT-L/TR features an integrated charge pump which generates the necessary RS-232 voltage levels from a single power supply, eliminating the need for multiple voltage rails. It integrates two drivers, which convert TTL/CMOS logic levels to RS-232 levels, and two receivers, which convert RS-232 levels back to TTL/CMOS logic levels. The enhanced ESD protection provides increased resilience against electrostatic discharge events. The 'TR' suffix indicates that the part is supplied in tape and reel packaging for automated assembly. The 'L' indicates lead-free construction.
