Section 8.1 “Minimizing I DD when the I/Os are used to control LEDs” ,
1 st
paragraph,
3 rd sentence changed from “The supply current, I DD , increases as V I becomes lower than
V DD and is speci?ed as ? I DD in Table 13 “Static characteristics” .” to “The supply current, I DD ,
increases as V I becomes lower than V DD .”

Table 13 “Static characteristics” , sub-section “Supplies”: removed ? I DD characteristic
Table 13 “Static characteristics” , sub-section “I/Os”, symbol I OL , LOW-level output current:
– condition V OL = 0.4 V; V DD = 2.3 V: changed Min value from “9 mA” to “6 mA”;
changed Typ value from “-” to “9 mA”
– condition V OL = 0.4 V; V DD = 3.0 V: changed Min value from “11 mA” to “8 mA”;
changed Typ value from “-” to “11 mA”
– condition V OL = 0.4 V; V DD = 5.0 V: changed Min value from “14 mA” to “10 mA”;
changed Typ value from “-” to “14 mA”
– condition V OL = 0.7 V; V DD = 2.3 V: changed Min value from “14 mA” to “11 mA”;
changed Typ value from “-” to “14 mA”
– condition V OL = 0.7 V; V DD = 3.0 V: changed Min value from “18 mA” to “14 mA”;
changed Typ value from “-” to “18 mA”
– condition V OL = 0.7 V; V DD = 5.0 V: changed Min value from “24 mA” to “17 mA”;
changed Typ value from “-” to “24 mA”
