Remote 16-bit I/O expander for I2C-bus with interrupt
12. Static characteristics
[1]
The power-on reset circuit resets the I2C-bus logic with VDD <VPOR and set 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 400 mA due to internal busing limits.
[3]
The value is not tested, but veried on sampling basis.
Table 5.
Static characteristics
VDD = 2.3 V to 5.5 V; VSS =0V; Tamb = 40 °Cto+85 °C; unless otherwise specied.
