The pin current may be slightly higher than the default value. You must verify that the driving device's V
maximum and V
voltage specifications.
Altera recommends that you use an external clamp diode on the column I/O pins when the input signal is 3.0 V or
3.3 V.

The Stratix III VCCPD power pins must be connected to a 2.5-, 3.0-V, or
3.3-V power supply. Using these power pins to supply the pre-driver
power to the output buffers increases the performance of the output pins.

Stratix III devices feature dynamic series and parallel on-chip termination
to provide I/O impedance matching and termination capabilities.
On-chip termination (OCT) maintains signal quality, saves board space,
and reduces external component costs.
Stratix III devices support on-chip series (R
parallel (R
termination for single-ended I/O standards and on-chip differential
termination (R
