I am trying to build universal flash cable for mobile phone through RS232 port, i found LG GD75323D in an old modem can i used it instead of MAX232 and also is it somewhat same as Max232, please help me.
gd75323d is not pin-compatible with max232, but if you build this cable from scraches you can use max232 and replace each driver/receiver from the GD with driver/receiver from MAX.
Download GD's data sheet from here:

This GD thingf requires 3 voltages: Vdd(+9 nom), Vss(-9V nom) and standard Vcc (+5V), but if you replace it with MAX232 you will be using only single +5V.
