TRS3232: Supply change impact on RS3232 part

Part Number:TRS3232

Hi Team,

Our customer is using TRS3232 device and changes design from 5Vcc to 3.3Vcc. Can this change in supply from 5V to 3.3V, create any impact on lines RIN (13^th pin) and DOUT(14^th pin). Is there any variation on voltage levels.

Thanks in advance for the help and support. 

Regards, Shinu Mathew.
