Electrical and Thermal Characteristics

This section provides AC and DC electrical specifications and thermal characteristics for the MPC8260.

2.1

DC Electrical Characteristics

This section describes the DC electrical characteristics for the MPC8260. Table 1 shows the maximum

electrical ratings.

Table 1. Absolute Maximum Ratings1

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.
