Specifications

The DSP56L307 is fabricated in high-density CMOS with transistor-transistor logic (TTL) compatible inputs and

outputs.

Note:

The DSP56L307 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.

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.

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 VCC).
