The 250 kbps data rate covers standard serial speeds up to 115.2 kbps with margin; if your application pushes past that, the 250 kbps ceiling is the hard limit.
It belongs in office equipment, test gear, or indoor industrial controllers — not in an engine bay or an outdoor telecom cabinet.
The difference is the package: MAX3232CDWRG4 ships in a 16-SOIC wide-body (7.50 mm width) on Tape & Reel, while MAX3232CDR is the same die in a narrower 16-SOIC (3.90 mm width). The wide-body variant has a larger footprint and different pad layout — verify your PCB land pattern before substituting.
Yes. The RS-232 driver outputs swing to the supply rail, so at 5 V supply the output levels are compatible with 5 V logic inputs on the remote side.
