Chapter 1: DC and Switching Characteristics for Stratix IV Devices
Electrical Characteristics
1–12
I/O Standard Specifications
Table 1–17 through Table 1–22 list the input voltage (VIH and VIL), output voltage
(VOH and VOL), and current drive characteristics (IOH and IOL) for various I/O
standards supported by Stratix IV devices. These tables also show the Stratix IV
device family I/O standard specifications. VOL and VOH values are valid at the
corresponding IOH and IOL, respectively.
For an explanation of terms used in Table 1–17 through Table 1–22, refer to “Glossary”
on page 1–64.
