MAX232 is a very good and matured IC. I support it. But is it possible to use any alternation circuit like this in the place of MAX232? Will it be wise to use in a product which is running 24X7 for years?
Circuit:
This one I found in google while searching for alternation of MAX232.
Another question, as there are two pair of Rx & Tx in MAX232, is it possible to use both of them to communicate between 2 set of device pairs? I mean MCU to PC one set and another set is something like that. Will it harm MAX232?
Also, if optocoupler is used will it be safe or a good choice for a 24X7 running device? I found some UPS use only optocoupler to communicate between PC and UPS. Is it safe and reliable?
Again, I have no complain about MAX232, that IC is ok. But is there any good alternative solution for MAX232?
