• Description: Pcnettm-pci Single-chip Ethernet Controller For Pci Local Bus
• Manufacturer: Advanced Micro Devices

DC CHARACTERISTICS (continued)
Notes:
1. I OL1 applies to AD[31:00], C/ BE [3:0], REQ, and PAR
2. V OH does not apply to open–drain output pins.
3. I IL and I IH apply to all input pins except XTAL1.
4. I OZL and I OZH apply to all three-state output pins and bi-directional pins.
5. Outputs are CMOS and will be driven to rail if the load is not resistive.
6. Parameter not tested. Value determined by characterization.
7. Tested, but to values in excess of limits. Test accuracy not sufficient to allow screening guard bands.
8. Correlated to other tested parameters – not tested directly.
9. Test not implemented to data sheet specification.
10. C IN = 8 pF for IDSEL input.
