ELECTRICAL SPECIFICATIONS

Data Sheet

The AC and DC specifications for the FWH Interface signals (FWH[3:0], CLK, FWH4, and RST#) as defined in Section

4.2.2 of the PCI Local Bus Specification, Rev. 2.1. Refer to Table 10 for the DC voltage and current specifications. Refer

to the tables on pages 23 through 27 for the AC timing specifications for Clock, Read/Write, and Reset operations.

Absolute Maximum Stress Ratings (Applied conditions greater than those listed under “Absolute Maximum

Stress Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation

of the device at these conditions or conditions greater than those defined in the operational sections of this data

sheet is not implied. Exposure to absolute maximum stress rating conditions may affect device reliability.)

1. Do not violate processor or chipset limitations on the INIT# pin.

2. Excluding certain with-Pb 32-PLCC units, all packages are 260°C capable in both non-Pb and with-Pb solder versions.

Certain with-Pb 32-PLCC package types are capable of 240°C for 10 seconds; please consult the factory for the latest information.

3. Outputs shorted for no more than one second. No more than one output shorted at a time. This note applies to non-PCI outputs.
