This chapter contains details on power considerations, DC/AC electrical characteristics, and AC timing specifications. For
additional information, see the MSC8102 User’s Guide and MSC8102 Reference Manual.
2.1 Maximum Ratings
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 V_DD).
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 MSC8102.

Notes: 1. Functional operating conditions are given in Table 2-2.
2. Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond
the listed limits may affect device reliability or cause permanent damage.
3. Section 4.5, , on page 4-6 includes a formula for computing the chip junction temperature (T_J).
