QPro Virtex 2.5V QML High-Reliability FPGAs
DC Input and Output Levels
Values for VIL and VIH are recommended input voltages.
Values for IOL and IOH are guaranteed output currents over
the recommended operating conditions at the VOL and VOH
test points. Only selected standards are tested. These are
chosen to ensure that all standards meet their specifica-
tions. The selected standards are tested at minimum VCCO
with the respective VOL and VOH voltage levels shown.
Other standards are sample tested.
