Hrm. Yeah. the datasheets on the MAX3232 (http://www.maxim-ic.com/quick_view2.cfm/qv_pk/1068/t/al) and MAX232 (http://www.maxim-ic.com/quick_view2.cfm/qv_pk/1798/t/al) show quite the difference: 5V/3...@.03ma vs. 5...@5ma. Hrm. Even thought the "Key Specifications" for the MAX232 says 5V, the "Key Features" says "+3.0V to +5.5V". Does look like the MAX3232 is the better option. Oh well, mine is ordered at this point so no changing my mind. Cheers, b.
