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 VCC rise time is 100 ms, and VCC must rise monotonically.
(5) FLEX 10KA device inputs may be driven before VCCINT and VCCIO are powered.
(6) Typical values are for TA = 25° C and VCC = 3.3 V.
(7) These values are specified under Table 27 on page 49.
(8) The IOH parameter refers to high-level TTL, PCI, or CMOS output current.
(9) The IOL parameter refers to low-level TTL, PCI, or CMOS output current. This parameter applies to open-drain pins
as well as output pins.
(10) This parameter applies to all -1 speed grade commercial temperature devices and all -2 speed grade
industrial-temperature devices.
(11) Capacitance is sample-tested only.
Figure 22 shows the typical output drive characteristics of EPF10K10A,
EPF10K30A, EPF10K100A, and EPF10K250A devices with 3.3-V and 2.5-V
V
. The output driver is compliant with the 3.3-V PCI Local Bus
CCIO
Specification, Revision 2.2 (with 3.3-V V
). Moreover, device analysis
CCIO
shows that the EPF10K10A, EPF10K30A, and EPF 10K100A devices can
drive a 5.0-V PCI bus with eight or fewer loads.
