APEX 20K Programmable Logic Device Family Data Sheet
Notes to tables:
(1) See the Operating Requirements for Altera Devices Data Sheet.
(2) Minimum DC 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.

(6) Typical values are for T = 25° C, VCCINT = 2.5 V, and VCCIO = 2.5 or 3.3 V.

(7) These values are specified in the APEX 20K device recommended operating conditions, shown in Table 26 on
page 62.
(8) The APEX 20K input buffers are compatible with 2.5-V and 3.3-V (LVTTL and LVCMOS) signals. Additionally, the
input buffers are 3.3-V PCI compliant when V
and V
meet the relationship shown in Figure 33 on page 68.

(9) The I
parameter refers to high-level TTL, PCI or CMOS output current.
OH
(10) 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.
(11) This value is specified for normal device operation. The value may vary during power-up.
(12) Pin pull-up resistance values will be lower if an external source drives the pin higher than V
(13) Capacitance is sample-tested only.
