I just want to establish some serial communication between my computer and a PIC controller. Like David mentioned, RS232 is actually +/- 10V rather than +/- 5V. The levels directly from controller are obviously only 0V and 5V. Now I am thinking, for the Rx input this is not a problem because it will easily handle the +/- 10V input signals if I add a series resistor. But the Tx output needs to go from 0V/5V to +/- 10V which is normally done with a MAX232 for example. The MAX has 4 line converters (2 input; 2 output) but I only need 1 for my Tx signal. So I was after something smaller like an 8 pin or even a 5 pin driver that works on just a +5V supply.
