Minimum DC input voltage is –0.5 V. During transitions, the inputs may undershoot to –2.0 V for input currents
less than 100 mA and periods shorter than 20 ns.
Numbers in parentheses are for industrial- and extended-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 ACEX 1K Recommended Operating Conditions shown in Table 19 on page 46.
The ACEX 1K input buffers are compatible with 2.5-V, 3.3-V (LVTTL and LVCMOS), and 5.0-V TTL and CMOS
signals. Additionally, the input buffers are 3.3-V PCI compliant when V
