Electrical characteristics

Input/output AC characteristics

The definition and values of input/output AC characteristics are given in Figure 24 and

Table 55, respectively. Unless otherwise specified, the parameters given are derived from

tests performed under the ambient temperature and supply voltage conditions summarized

in Table 24: General operating conditions.
