Remote 8-bit I/O expander for Fm+ I2C-bus with interrupt
13. Static characteristics
[1]
The power-on reset circuit resets the I2C-bus logic with VDD <VPOR and sets all I/Os to logic 1 (with current source to VDD).
[2]
Each bit must be limited to a maximum of 25 mA and the total package limited to 200 mA due to internal busing limits.
[3]
The value is verified by characterization.
