Remote 16-bit I/O expander for Fm+ I2C-bus with reset
10.2 High current-drive load applications
The GPIO has a maximum sinking current of 25 mA per bit. In applications requiring
additional drive, two port pins in the same octal may be connected together to sink up to
50 mA current. Both bits must then always be turned on or off together. Up to 8 pins (one
octal) can be connected together to drive 200 mA.
11. Limiting values
[1]
Total package (maximum) output current is 600 mA.
