4. Electrical and Thermal Characteristics
This section provides both AC and DC electrical specifications, and thermal characteristics for the PowerPC
750CXe.
4.1 DC Electrical Characteristics
The tables in this section describe the PowerPC 750CXe’s DC electrical characteristics. Table 4-1 provides
the absolute maximum ratings.

1. Functional and tested operating conditions are given in Table 4-2 on page 7. Absolute maximum ratings are stress ratings only, and functional operation
at the maximums is not guaranteed. Stresses beyond those listed above may affect device reliability or cause permanent damage to the device.
2. Caution: VIN must not exceed OVDD by more than 0.6V at any time, including during power-on reset. This is a DC specification only. VIN overshoot tran-
sients up to OVDD+0.8v,and undershoots down to GND-0.8v (both measured with the 750CXe in the circuit) are allowed for up to 5ns or 1/3 bus clock
cycle, whichever is less.
3. Caution: OVDD must not exceed VDD/AVDD by more than 2.0V, except for up to 20ms during power on/off reset.
4. Caution: VDD/AVDD must not exceed OVDD by more than 1.2V, except for up to 20ms during power up/down.
5. Caution: AVDD must not exceed VDD by more than 1.2V, except for up to 20ms during power up/down reset.
Table 4-2 provides the recommended operating conditions for the PowerPC 750CXe.
