• Manufacturer Part Number: AM79C971VCW
• Description: PCnet-FAST Single-Chip Full-Duplex 10/100 Mbps Ethernet Controller for PCI Local Bus
• Manufacturer: Advanced Micro Devices

3. VOH does not apply to open-drain output pins.
4. OH1 applies to all other outputs.
5. IL and IIH apply to all input pins except XTAL1.
6. OZL and IOZH apply to all three-state output pins and bidirectional pins.
7. Parameter not tested. Value determined by characterization.
8. Tested, but to values in excess of limits. Test accuracy not sufficient to allow screening guard bands.
9. Correlated to other tested parameters - not tested directly.
10. Test not implemented to data sheet specification.
11. CIN = 8 pF for the IDSEL input and all input pins on the MII interface (TX_CLK, COL, CRS, RX_CLK, RXD[3:0], RX_DV,
12. The power supply current in Magic Packet mode is linear with respect to the PCI Clock frequency operation, assuming the
