Introduction

This chapter provides preliminary information on absolute maximum

ratings, recommended operating conditions, DC electrical characteristics,

and other specifications for HardCopy® II devices.

Absolute

Maximum

Ratings

HardCopy II devices are offered in both commercial and industrial

grades. All parameter limits are representative of worst-case supply

voltage and junction temperature conditions. Unless otherwise noted, the

parameter values in this chapter apply to all HardCopy II devices.

Table 4–1 contains the absolute maximum ratings for the HardCopy II

device family.

Notes to Table 4–1:

(1)

Refer to the Operating Requirements for Altera Devices Data Sheet for more information.

(2)

Conditions beyond those listed in Table 4–1 may cause permanent damage to a device. Additionally, device

operation at the absolute maximum ratings for extended periods of time may have adverse effects on the device.

(3)

Supply voltage specifications apply to voltage readings taken at the device pins, not at the power supply.

(4)

During transitions, the inputs may overshoot to the voltage shown in Table 4–2 based upon the input duty cycle.

The DC case is equivalent to a 100% duty cycle. During transitions, the inputs may undershoot to –2.0 V for input

currents less than 100 mA and periods shorter than 20 ns.
