1. DC and Switching Characteristics of

HardCopy III Devices

Electrical Characteristics

This chapter provides information about the absolute maximum ratings,

recommended operating conditions, DC electrical characteristics, and other

commercial and industrial grades.

Operating Conditions

When HardCopy III devices are implemented in a system, they are rated according to

a set of defined parameters. To maintain the highest possible performance and

reliability, you must consider the operating requirements described in this chapter.

HardCopy III devices are designed and built to function at a target frequency based

on timing constraints, and operate at either commercial or industrial temperatures.

Absolute Maximum Ratings

Absolute maximum ratings define the maximum operating conditions for

HardCopy III devices. The values are based on experiments conducted with the

device and theoretical modeling of breakdown and damage mechanisms. The

functional operation of the device is not implied by these conditions. Conditions

beyond those listed in Table 1–1 can cause permanent damage to the device.

Additionally, device operation at the absolute maximum ratings for extended periods

of time can have adverse effects on the device.
