Symbol

Parameter

Conditions(1)

1. The IIO current sourced or sunk by the device must always respect the absolute maximum rating specified

in Table 16, and the sum of the currents sourced or sunk by all the I/Os (I/O ports and control pins) must

always respect the absolute maximum ratings ΣIIO.
