    Electrical and Thermal Characteristics
    Table 4 provides the recommended operating conditions for the MPC7447A.
    NOTE
    Table 4 describes the nominal operating conditions of the device. For
    information regarding the operation of the device at supported derated core
    Table 5 provides the package thermal characteristics for the MPC7447A.

    Notes:
    1. Caution: The input threshold selection must agree with the OVDD voltages supplied. See notes in Table 2.
    2. If used, pull-down resistors should be less than 250
    Ω.

    Notes:
    1. These are the recommended and tested operating conditions. In addition, these devices also support voltage
    derating; see Section 5.3, “Voltage and Frequency Derating.” Proper device operation outside of these conditions
    and those specified in Section 5.3 is not guaranteed.
    2. This voltage is the input to the filter discussed in Section 9.2, “PLL Power Supply Filtering,and not necessarily the
    voltage at the AVDD pin, which may be reduced from VDD by the filter.
    3. VDD and AVDD may be reduced in order to reduce power consumption if further maximum core frequency
    constraints are observed. See Section 5.3, “Voltage and Frequency Derating,for specific information.
