Notes to Table 5–5 through Table 5–9:
(1) This specification is supported across all the programmable drive strength settings available for this I/O standard, as shown
in the MAX II Architecture chapter (I/O Structure section) in the MAX II Device Handbook.
(2) This maximum V_IH reflects the JEDEC specification. The MAX II input buffer can tolerate a V_IH maximum of 4.0, as specified
by the V_I parameter in Table 5–2.
