– Input SCL; input/output SDA

change IOL Typ. (VOL = 0.4 V) from “–” to 7 mA

change IOL Typ. (VOL = 0.6 V) from “–” to 10 mA

change Ci Typ. from 12 pF to 10 pF

– Select inputs A0 to A2 / INT0 to INT3

change Test conditions for ILI from “pin at VDD or VSS” to “VI = VDD or VSS”

– INT output

change IOL Typ. from “–” to 7 mA

change IOH Max. from +100 µA to +10 µA

– Add Note 2.

• DC characteristics table (V

DD = 4.5 V to 5.5 V) on page 12:

– change description from “VDD = 3.6 V to 5.5 V” to “VDD = 4.5 V to 5.5 V”

– Supply

change VDD Min. from 3.6 V to 4.5 V

change IDD Typ. from 65 µA to 25 µA

– Input SCL; input/output SDA

remove parameters IIL and IIH

add parameter IL

– Select inputs A0 to A2 / INT0 to INT3; change ILI Max. from +50 µA to +1 µA

– Pass Gate

change IL Min. from –10 µA to –1 µA

change IL Max. from +100 µA to +1 µA

– INT output; change IOH Max from +100 µA to +10 µA

– Add Note 2.

• AC characteristics table on page 13:
