3.2. Electrical Specifications
3.2.1. Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the 92HD66C. These ratings, which are stan-
dard 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 guar-
anteed only over the recommended operating temperature range.
