Specifications
2.1 Introduction
This document contains detailed information on power considerations, DC/AC electrical characteristics,
and AC timing specifications for the MSC8101 communications processor. For additional information,
see the MSC8101 Reference Manual.
Note:
2.2 Absolute Maximum Ratings
In calculating timing requirements, adding a maximum value of one specification to a minimum value of
another specification does not yield a reasonable sum. A maximum specification is calculated using a
worst case variation of process parameter values in one direction. The minimum specification is
calculated using the worst case for the same parameters in the opposite direction. Therefore, a
"maximum" value for a specification never occurs in the same device with a "minimum" value for
another specification; adding a maximum to a minimum represents a condition that can never exist.
Table 2-1 describes the maximum electrical ratings for the MSC8101.

The MSC8101 electrical specifications are preliminary and many are from design simulations.
These specifications may not be fully tested or guaranteed at this early stage of the product life
cycle. Finalized specifications will be published after thorough characterization and device
qualifications have been completed.
This device contains circuitry protecting against damage due to
high static voltage or electrical fields; however, normal precautions
should be taken to avoid exceeding maximum voltage ratings.
Reliability is enhanced if unused inputs are tied to an appropriate
logic voltage level (for example, either GND or V
