Hello engineers;
        I would like to buy a max232. But there are lots of
them in the market.
        I have some of them on my mind and don't know which
to choose. Can you tell me what's the difference and which is
the best? I'm using for one transmit and one receive. And
I'm concerned if they are using 5volts.
        Here are some of them on my mind:
        MAX233CPP
        MAX232CPE
        ICL232CPE
        HIN232CP/CB/IB
