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 12 for the DC voltage

and current specifications. Refer to the tables on pages 24 through 29 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 con-

ditions 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.
