Notes to Table 1–1:
(1) Supply voltage specifications apply to voltage readings taken at the device pins and not the power supply.
(2) In Stratix III devices, this power supply is also used for programmable power technology.
(3) In HardCopy III devices, this power supply is not used.
Maximum Allowed Overshoot and Undershoot Voltage
During transitions, input signals may overshoot to the voltage shown in Table 1–2 and
undershoot to –2.0 V for input currents less than 100 mA and periods shorter than
20 ns.
Table 1–2 lists the maximum allowed input overshoot voltage. The maximum allowed
overshoot duration is specified as the percentage of high time over the lifetime of the
device. A DC signal is equivalent to 100% duty cycle.
