Specifications

This document contains detailed information on power considerations, DC/AC electrical characteristics, and AC

timing specifications. For additional information, see the MSC8122 User’s Guide and MSC8122 Reference

Manual.

2.1 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.

CAUTION

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 VDD).
