797 / 1061 page ![]() Section 25 Electrical Characteristics Rev. 4.00 Jun 06, 2006 page 743 of 1004 REJ09B0301-0400 Table 25.17 Permissible Output Currents Conditions: V CC = 4.0 V to 5.5 V, VSS = 0 V, Ta = –20 to +75°C (regular specifications), T a = –40 to +85°C (wide-range specifications) Item Symbol Min Typ Max Unit Permissible output low current (per pin) SCL1, SCL0, SDA1, SDA0 I OL —— 20 mA Ports 1 to 3 —— 10 mA Other output pins —— 2mA Total of ports 1 to 3 ∑ I OL —— 80 mA Permissible output low current (total) Total of all output pins, including the above —— 120 mA Permissible output high current (per pin) All output pins –I OH —— 2mA Permissible output high current (total) Total of all output pins ∑ –I OH —— 40 mA Conditions: V CC = 2.7 V to 3.6 V, VSS = 0 V, Ta = –20 to +75°C Item Symbol Min Typ Max Unit Permissible output low current (per pin) SCL1, SCL0, SDA1, SDA0 I OL —— 10 mA Ports 1 to 3 —— 2mA Other output pins —— 1mA Total of ports 1 to 3 ∑ I OL —— 40 mA Permissible output low current (total) Total of all output pins, including the above —— 60 mA Permissible output high current (per pin) All output pins –I OH —— 2mA Permissible output high current (total) Total of all output pins ∑ –I OH —— 30 mA Notes: 1. To protect chip reliability, do not exceed the output current values in table 25.17. 2. When driving a Darlington pair or LED, always insert a current-limiting resistor in the output line, as show in figures 25.1 and 25.2. |
