Input/output AC characteristics

The definition and values of input/output AC characteristics are given in Figure 19 and

Table 44, respectively.

Unless otherwise specified, the parameters given in Table 44 are derived from tests

performed under ambient temperature and VDD supply voltage conditions summarized in

Table 13.
