See the Operating Requirements for Altera Devices Data Sheet.
Minimum DC input is –0.5 V. During transitions, the inputs may undershoot to –2.0 V or overshoot to 4.6 V for input
currents less than 100 mA and time periods shorter than 20 ns.
Numbers in parentheses are for industrial-temperature-range devices.
Maximum V
All pins, including dedicated inputs, clock, I/O, and JTAG pins, may be driven before V
powered.
Typical values are for T
These values are specified under the APEX 20KC device recommended operating conditions, shown in
page
This value is specified for normal device operation. The value may vary during power-up.
Pin pull-up resistance values will be lower if an external source drives the pin higher than V
