Operating Conditions
Table 5–4 shows the maximum VIN overshoot voltage and the
dependency on the duty cycle of the input signal. Refer to Table 5–3 for
more information.

Notes to Table 5–3:
(1)
All pins, including dedicated inputs, clock, I/O, and JTAG pins, may be driven before VCCINT and VCCIO are
powered.
(2)
The minimum DC input is –0.5 V. During transitions, the inputs may undershoot to –2.0 V or overshoot to the
voltages shown in Table 5–4, based on input duty cycle for input currents less than 100 mA. The overshoot is
dependent upon duty cycle of the signal. The DC case is equivalent to 100% duty cycle.
(3)
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).
(4)
Maximum values depend on the actual TJ and design utilization. See the Excel-based PowerPlay Early Power
Estimator (www.altera.com) or the Quartus II PowerPlay Power Analyzer feature for maximum values. Refer to
“Power Consumption” on page 5–13 for more information.
(5)
RCONF values are based on characterization. RCONF = VCCIO/IRCONF. RCONF values may be different if VIN value is
not 0 V. Pin pull-up resistance values will be lower if an external source drives the pin higher than VCCIO.
(6)
Minimum condition at –40°C and high VCC, typical condition at 25°C and nominal VCC and maximum condition at
125°C and low VCC for RCONF values.
(7)
These values apply to all VCCIO settings.
