However, the Max232 uses a fair amount of power to drive the charge pumps, which you would then just be throwing away. If you just used a DS2480 directly you can connect to TTL level signals avoiding two max232 type level shifters. The DS2480 has a polarity select pin which allows you to ensure the phase is correct. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2923 njh ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
