210 / 283 page  Electrical characteristics STM32U545xx 210/283 DS14216 Rev 1 Output AC characteristics The definition and values of output AC characteristics are given in Figure 35: Output AC characteristics definition and in the table below respectively. Unless otherwise specified, the parameters given are derived from tests performed under the ambient temperature and supply voltage conditions summarized in Table 33. Table 96.
