Output Driving Current

Subject to general operating conditions for VDD and TA unless otherwise specified.

Notes:

The IIO current sunk must always respect the absolute maximum rating specified in Table 5 and the sum of

IIO (I/O ports and control pins) must not exceed IVSS.

The IIO current sourced must always respect the absolute maximum rating specified in Table 5 and the

sum of IIO (I/O ports and control pins) must not exceed IVDD.
