Take a look at the Linear Tech. LTC1642. http://www.linear.com/prod/datasheet.html?datasheet=642 and http://www.linear.com/prod/datasheet.html?datasheet=472 "The LTC®1694 [-1] is a dual SMBus active pull-up designed to enhance data transmission speed and reliability under all specified SMBus loading conditions. The LTC1694 [-1] is also compatible with the Philips I²C Bus." -- http://www.softwaresafety.net/ http://www.unusualresearch.com/ http://www.bpaddock.com/ _______________________________________________ avr-gcc-list mailing list address@hidden http://www.avr1.org/mailman/listinfo/avr-gcc-list
