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

Ω.

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.
