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 V
DD
supply voltage conditions summarized in
Table 7 .
