Output Driver Characteristics
Table 4 provides information on the characteristics of the output drivers referenced in Table 17. The values
are preliminary estimates from an IBIS model and are not tested.

Notes:
1. See Table 17 for pins with internal pull-up resistors.
2. All grounded pins are connected together.
3. Leakage current is measured on input and output pins in the high-impedance state. The leakage current is
measured for nominal GVDD_OVDD/LVDD and VDD or both GVDD_OVDD/LVDD and VDD must vary in the same
direction.
4. See Table 4 for the typical drive capability of a specific signal pin based on the type of output driver associated with
that pin as listed in Table 17.

Notes:
1. For DRV_PCI, IOH read from the IBIS listing in the pull-up mode, I(Min) column, at the 0.33-V label by interpolating
between the 0.3- and 0.4-V table entries current values which corresponds to the PCI VOH = 2.97 = 0.9 ×
GVDD_OVDD (GVDD_OVDD = 3.3 V) where table entry voltage = GVDD_OVDD – PCI VOH.
2. For all others with GVDD_ OVDD = 3.3 V, IOH read from the IBIS listing in the pull-up mode, I(Min) column, at the
0.9-V table entry which corresponds to the VOH = 2.4 V where table entry voltage = GVDD_OVDD – VOH.
3. For DRV_PCI, IOL read from the IBIS listing in the pull-down mode, I(Min) column, at 0.33 V = PCI VOL = 0.1 ×
GVDD_OVDD (GVDD_OVDD = 3.3 V) by interpolating between the 0.3- and 0.4-V table entries.
4. For all others with GVDD_OVDD = 3.3 V, IOL read from the IBIS listing in the pull-down mode, I(Min) column, at the
0.4-V table entry.
5. See driver bit details for output driver control register (0x73) in the MPC8245 Integrated Processor User’s Manual.
6. See Chip Errata No. 19 in the MPC8245/MPC8241 Integrated Processor Chip Errata.
