12 / 29 page ![]() M69AW048B 12/29 DC AND AC PARAMETERS This section summarizes the operating measure- ment conditions, and the DC and AC characteris- tics of the device. The parameters in the DC and AC characteristics Tables that follow, are derived from tests performed under the Measurement Conditions summarized in Table 8., Operating and AC Measurement Conditions. Designers should check that the operating conditions in their circuit match the operating conditions when relying on the quoted parameters. Table 8. Operating and AC Measurement Conditions Note: 1. All voltages are referenced to VSS. 2. The Input Transition Time used in AC measurements is 5ns. For other input transition times, see Table 8. Figure 5. AC Measurement I/O Waveform Figure 6.
