Chapter 2 Specifications; Maximum Ratings - Freescale Semiconductor DSP56311 Technical Data Manual

Specifications
The DSP56311 is fabricated in high-density CMOS with transistor-transistor logic (TTL) compatible inputs and
outputs.

2.1 Maximum Ratings

In the calculation of 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 that has a "minimum" value for another specification; adding a maximum to a minimum
represents a condition that can never exist.

2. Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond
the maximum rating may affect device reliability or cause permanent damage to the device.
3. Power-up sequence: During power-up, and throughout the DSP56311 operation, V
equal to V voltage.

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
