C-bus/SMBus I/O expander
[1] For I
DD
, all typical values are at nominal supply voltage (1.8 V, 2.5 V, 3.3 V, 3.6 V or 5 V V
DD
) and T

=25C.
[2] The total current sourced by all I/Os must be limited to 160 mA.
[3] Each I/O must be externally limited to a maximum of 25 mA and each octal (P0_0 to P0_7 and P1_0 to P1_7) must be limited to a
maximum current of 100 mA, for a device total of 200 mA.
