Notes to Table 3–9:
(1) This specification is supported across all the programmable drive strength settings available for this I/O standard, as shown in the
MAX V Device Architecture chapter.
(2) This maximum VIH reflects the JEDEC specification. The MAX V input buffer can tolerate a VIH maximum of 4.0, as specified by the VI parameter
in Table 3–2 on page 3–2.
