I mean to say that, I wanted to use transmission with 3.3V and my reception is with 5V can i use a 3.3v transmission for that receiver using MAX232?
 

When MAX232 is connected to 5v supply then

VIL Low-level input voltage (T1IN, T2IN) 0.8v
VIH High-level input voltage (T1IN,T2IN) 2v

so it will work fine, you can send 3.3v signals and receive 5v signals (I assume your mcu is 5v tolerant)
 
Thanks for your valuable reply..
