Notes to tables:
(1) See the Operating Requirements for Altera Devices Data Sheet.
(2) Minimum DC voltage input is –0.5 V. During transitions, the inputs may undershoot to –2.0 V or overshoot to 5.75 V
for input currents less than 100 mA and periods shorter than 20 ns.
(3) Numbers in parentheses are for industrial-temperature-range devices.
(4) Maximum V rise time is 100 ms, and V must rise monotonically.
CC
CC
(5) FLEX 10KA device inputs may be driven before V
and V
are powered.
CCINT
CCIO
(6) Typical values are for T = 25° C and V
= 3.3 V.
A
CC
(7) These values are specified under the Recommended Operating Conditions shown in Table 27 on page 51.
(8) The I parameter refers to high-level TTL, PCI, or CMOS output current.
OH
(9) The I parameter refers to low-level TTL, PCI, or CMOS output current. This parameter applies to open-drain pins
OL
as well as output pins.
(10) This value is specified for normal device operation. The value may vary during power-up.
(11) This parameter applies to all -1 speed grade commercial temperature devices and all -2 speed grade
industrial-temperature devices.
(12) Capacitance is sample-tested only.
