Input/output AC characteristics

The definition and values of input/output AC characteristics are given in Figure 16 and

Table 31, respectively.

Unless otherwise specified, the parameters given in Table 31 are derived from tests

performed under ambient temperature and VDD supply voltage conditions summarized in

Table 7.
