LOW SKEW PCI/PCI-X BUFFER FAN OUT BUFFER IDT® LOW SKEW PCI/PCI-X BUFFER 3 ICS2304NZ-1 REV G 110110 Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the ICS2304NZ-1. These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range. Notes: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. This value is limited to 4.6 V maximum. 3. The package thermal impedance is calculated in accordance with JESD 51.
