The 'must have' IC for 3V projects. This is the RS232 converter IC that is capable of running at 3V and communicating with 3V logic. Comes in a DIP package. Requires four external capacitors. The MAX232 can use very small 0.1uF ceramic capacitors - no more 10uF monsters! Operates from 2.7V to 6V so this DIP will work with your 5V projects or your 3V projects.
