Notes to Table 4–1:
(1) See the operating requirements for Altera® devices in the Arria GX Device Family Data Sheet in volume 1 of the
Arria GX Device Handbook 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 affects 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 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.
