Electrical Characteristics
This chapter covers the electrical characteristics for Stratix IV devices.
Operating Conditions
When Stratix
®
IV devices are implemented in a system, they are rated according to a
set of defined parameters. To maintain the highest possible performance and
reliability of Stratix IV devices, system designers must consider the following
operating requirements. Stratix IV devices are offered in both commercial and
industrial grades. Commercial devices are offered in -2 (fastest), -2x, -3, and -4 speed
grades.
Absolute Maximum Ratings
Absolute maximum ratings define the maximum operating conditions for Stratix IV
devices. The values are based on experiments conducted with the devices and
theoretical modeling of breakdown and damage mechanisms. The functional
operation of the device is not implied at these conditions.
1
Conditions beyond those listed in
Table 1–1
and
Table 1–2
may cause permanent
damage to the device. Additionally, device operation at the absolute maximum
ratings for extended periods of time may have adverse effects on the device.

Maximum Allowed Overshoot/Undershoot Voltage
During transitions, input signals may overshoot to the voltage shown in
Table 1–3
and undershoot to -2.0 V for input currents less than 100 mA and periods shorter than
20 ns.
Table 1–3
lists the maximum allowed input overshoot voltage and the duration of the
overshoot voltage as a percentage of device lifetime. The maximum allowed
overshoot duration is specified as a percentage of high-time over the lifetime of the
device. A DC signal is equivalent to 100% duty cycle. For example, a signal that
overshoots to 4.3 V can only be at 4.3 V for ~5% over the lifetime of the device; for a
device lifetime of 10 years, this amounts to 5/10ths of a year.

Recommended Operating Conditions
This section lists the functional operation limits for AC and DC parameters for
Stratix IV devices. The steady-state voltage and current values expected from
Stratix IV devices are provided in
Table 1–4.
All supplies must be strictly monotonic,
without plateaus.
