Output AC characteristics

Unless otherwise specified, the parameters given in Table 63 are at ambient temperature

and under the supply voltage conditions summarized in Table 26.

The definition and values of output AC characteristics are given, respectively, in Figure 16

and in Table 63.

1. The IIO current sourced or sunk by the device must always respect the absolute maximum rating specified in Table 22, 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 ΣI(PIN).

2. Specified by design, not tested in production.
