1.2 Electrical and Thermal Characteristics

This section provides both the AC and DC electrical specifications and thermal characteristics for the 604.

The following specifications are preliminary and subject to change without notice. For the most recent

specifications, contact your local Motorola or IBM sales office.

1.2.1 DC Electrical Characteristics

Table 1 and Table 2 provide the absolute maximum rating and thermal characteristics for the 604.

Notes:

1. Functional operating conditions are given in DC electrical specifications. Absolute

maximum ratings are stress ratings only, and functional operation at the maximums is

not guaranteed. Stresses beyond those listed may affect device reliability or cause

permanent damage to the device.

2. Caution: Input voltage must not be greater than the supply voltage by more than 2.5 V

during power-on reset.

Notes:

1. For the BGA package, the

θJC measurement is made from die junction to the back of the

bare silicon die.

2. The junction temperature of the chip is a function of several parameters including

θJC.
