Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 18 and
Table 39, respectively.
Unless otherwise specified, the parameters given in Table 39 are derived from tests
performed under ambient temperature and VDD supply voltage conditions summarized in
Table 9.
