Electrical characteristics
4. Based on characterization data, not tested in production.
Input/output AC characteristics
The definition and values of input/output AC characteristics are given in Figure 35 and
Table 45, respectively.
Unless otherwise specified, the parameters given in Table 45 are derived from tests
performed under the ambient temperature and VDD supply voltage conditions summarized
in Table 11.
