Notes to Tables 4â1 through 4â3:
(1) Refer to the Operating Requirements for Altera Devices Data Sheet.
(2) Conditions beyond those listed in Table 4â1 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) Minimum DC input is â0.5 V. During transitions, the inputs may undershoot to â2 V or overshoot to 4.6 V for input
currents less than 100 mA and periods shorter than 20 ns.
(4) Maximum VCC rise time is 100 ms, and VCC must rise monotonically.
(5) VCCIO maximum and minimum conditions for LVPECL, LVDS, and 3.3-V PCML are shown in parentheses.
(6) All pins, including dedicated inputs, clock, I/O, and JTAG pins, may be driven before VCCINT and VCCIO are
powered.
(7) Typical values are for TA = 25 °C, VCCINT = 1.5 V, and VCCIO = 1.5 V, 1.8 V, 2.5 V, and 3.3 V.
(8) This value is specified for normal device operation. The value may vary during power up. This applies for all VCCIO
settings (3.3, 2.5, 1.8, and 1.5 V).
(9) Pin pull-up resistance values will be lower if an external source drives the pin higher than VCCIO.
