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 4.6 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.

(7) These values are specified under the APEX 20K device recommended operating conditions, shown in Table 24 on
page 60.
(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.

Tables 27 through 30 provide information on absolute maximum ratings,
recommended operating conditions, DC operating conditions, and
capacitance for 5.0-V tolerant APEX 20K devices. These devices are
identified by a “V” suffix following the speed grade in the ordering code
(e.g., EP20K400BC652-1V).
