A Max127 has a adress  0101 A2 A1 A0 RW 01010000 = 80 01010010 = 82 01010100 = 84 01011000 = 88 ..and some more. You can use 8 Max127 on one i2c-bus. The begining 0101 is fixed and 01010000 = 80 dez. > I cant find itÂ…. > I understand Max127 adres+1 (write and +1 is read) > > And now my biggest problem > I cant order the MAX127 in the Netherlands > Conrad.nl, Farnell.

You can order two samples for free at the maxim-hp.
