MAX3243E: what is the RS232 output voltage swing level ?

Part Number: MAX3243E

Hi,

Because some vendor chip can achieve RS-232 swing level to 8V (output loaded 3k ohm to gnd)

Can MAX3243 achieve this level ?

I think the value on VOH High-level output voltage is the same definition, right ?

the value on MAX3243 (5v) is lower than I expect, could you provide other suggestion ?
