Specifications
3.1
Introduction
The DSP56362 is fabricated in high density CMOS with Transistor-Transistor Logic (TTL) compatible
inputs and outputs. The DSP56362 specifications are preliminary and are from design simulations, and
may not be fully tested or guaranteed. Finalized specifications will be published after full characterization
and device qualifications are complete.
3.2
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 of operation is
enhanced if unused inputs are pulled to an appropriate logic voltage level
(e.g., either GND or VCC). The suggested value for a pullup or pulldown
resistor is 10 k
.
NOTE
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
will never occur 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.
