Electrical and Thermal Characteristics
This section provides AC and DC electrical specifications and thermal characteristics for the MPC8250.
2.1
DC Electrical Characteristics
This section describes the DC electrical characteristics for the MPC8250. Table 1 shows the maximum
electrical ratings.
Table 2 lists recommended operational voltage conditions.
Table 1. Absolute Maximum Ratings 1
1
Absolute maximum ratings are stress ratings only; functional operation (see Table 2) at the maximums is not
guaranteed. Stress beyond those listed may affect device reliability or cause permanent damage.
