16-bit I2C-bus and SMBus I/O port with interrupt
[2]
Each I/O must be externally limited to a maximum of 25 mA and each octal (IO0_0 to IO0_7 and IO1_0 to IO1_7) must be limited to a
maximum current of 100 mA for a device total of 200 mA.
[3]
The total current sourced by all I/Os must be limited to 160 mA.
(1) IOH = 8mA
(2) IOH = 10 mA
(1) IOH = 8mA
(2) IOH = 10 mA
