Stratix & Stratix GX I/O Standards
Stratix and Stratix GX devices support both input and output levels for
2.5-V LVCMOS operation.
1.8-V LVTTL Normal Voltage Range - EIA/JEDEC Standard
EIA/JESD8-7
The 1.8-V I/O standard is used for 1.8-V LVTTL applications. This
standard defines the DC interface parameters for high-speed, low-
voltage, non-terminated digital circuits driving or being driven by other
1.8-V parts. The input and output voltage ranges are:
■ The 1.8-V normal range input standards specify an input voltage
range of – 0.5 V ≤V
I
≤2.3 V.
■ The normal range minimum V
OH
requirement is V
CCIO
–0.45 V.
Stratix and Stratix GX devices support both input and output levels for
1.8-V LVTTL operation.

1.5-V LVCMOS Normal Voltage Range - EIA/JEDEC Standard
JESD8-11
The 1.5-V I/O standard is used for 1.5-V applications. This standard
defines the DC interface parameters for high-speed, low-voltage, non-
terminated digital circuits driving or being driven by other 1.5-V devices.
The input and output voltage ranges are:
■ The 1.5-V normal range input standards specify an input voltage
range of – 0.5 V ≤V
I
≤2.0 V.
■ The normal range minimum V
OH
requirement is 1.05 V.
