DC AND AC PARAMETERS
This section summarizes the operating and mea-
surement conditions, as well as the DC and AC
characteristics of the device. The parameters in
the following DC and AC Characteristic tables are
derived from tests performed under the Measure-
ment Conditions listed in the relevant tables. De-
signers should check that the operating conditions
in their projects match the measurement condi-
tions when using the quoted parameters.
Table 9. DC and AC Measurement Conditions
Note: Output High Z is defined as the point where data is no longer driven (see
Table 9., page 18
).
Figure 12. AC Testing Load Circuit
Note: 50pF for M48T251V.
Table 10. Capacitance
Note: 1. Effective capacitance measured with power supply at 5V. Sampled only; not 100% tested.
2. At 25°C, f = 1MHz.
3. Outputs were deselected.
