E8870 Scalable Node Controller (SNC) Datasheet 9-1
Electrical Specifications 9
9.1 Non-operational Maximum Rating
The absolute maximum non-operational DC ratings are provided in Table 9-1. T. Functional
operation at the absolute maximum and minimum ratings is neither implied nor guaranteed. The
SNC should not receive a clock while subjected to these conditions. Functional operating
conditions are given in the AC and operational DC tables. Furthermore, although the SNC contains
protective circuitry to resist damage from static discharge, one should always take precautions to
avoid high static voltages or electric fields.
9.2 Operational Power Delivery Specification
SNC power requirements are outlined in this section. All parameters in Table 9-2 are specified at
the pin of the component package.
