I just learned that apparently (I have not looked at the data sheet myself) MAXIM has changed the function of pin 2 on their serial line driver chip. The old configuration was a polarized cap. tied to gnd. (that's the way I always wired them), and their data sheet now shows the cap. tied to vcc (I'm told). Could account for the heat, and short service life!!! *grin* Bottom line is check the data sheets, or stick with T.I. 232 chips (they still work the same old way). Wonder why they did this????
