12. Electrical Characteristics
12.2 Maximum Ratings
Table 12-5 contains stress ratings for the Intel^® 450NX PCIset. Functional operation at the
absolute maximum and minimum ratings is neither implied nor guaranteed. The Intel 450NX
PCIset should not receive a clock while subjected to these conditions. Functional operating
conditions are given in the AC and DC tables. Extended exposure to the maximum ratings
may affect device reliability. Furthermore, although the Intel 450NX PCIset contains
protective circuitry to resist damage from static discharge, care should always be taken to
avoid high static voltages or electric fields.
