MAX3221: CONFUSE WITH SOME PINS OF THE transceiver

Andrei Steve Charpentier Quesada
Prodigy 10 points
Part Number: MAX3221
Other Parts Discussed in Thread: MAX3223

Hi, im considering to use the max3221 for a project, but im a little confuse becaue i usually use not-shutdown power supply transnceivers and i didnt understand very well about UNVALID, EN, FORCEOFF, FORCEON, but as i understand the datasheet i did this diagram

i dont want to use the low power supply mode, i just want to use the disable power down mode, and in the datasheet says that if you put the forceon and forceoff to vcc it will be disable and EN to ground ROUT wil get a low impedance(that comunciation will be posible i guess)

so i want know that if this is correct to a comunication with a rs232 and uart port? also i want to add that my pcb only have a 5v power supply voltage, and no a 3.3v voltage supply.

thx for anyhelp
