He obviously means 5v logic to RS232.
MAX232 is a great chip I have used loads of times.

 are you looking for a dc-dc power converter, or a level converter to
 interface (say) a 5v chip to a 3.3v?  If the former, what power level
 and efficiency are you willing to pay for?  There are some really
 nifty led drivers in the $2 and under range.
 If the latter, most of the analog interface companies have a couple of
 lines.  I like Maxim's parametric search, but TI, Linear, and probably
 Analog Devices make them.  I think I search on "voltage level
 conversion ic" or "ttl conversion ic".
