Notes to
through
(1) This specification is supported across all the programmable drive strength settings available for this I/O standard, as shown
in the
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
ALTERA [ ALTERA CORPORATION ]
