FLEX 8000 Programmable Logic Device Family Data Sheet
Notes to tables:
(1)
(2)
Minimum DC input voltage is –0.3 V. During transitions, the inputs may undershoot to –2.0 V or overshoot to 5.3 V
for input currents less than 100 mA and periods shorter than 20 ns.
(3)
The maximum VCC rise time is 100 ms. VCC must rise monotonically.
(4)
(5)
The IOH parameter refers to high-level TTL output current; the IOL parameter refers to low-level TTL output current.
(6)
Typical values are for TA = 25° C and VCC = 3.3 V.
(7)
Capacitance is sample-tested only.
Figure 16 shows the typical output drive characteristics of 5.0-V
FLEX 8000 devices. The output driver is compliant with PCI Local Bus
Specification, Revision 2.2
.
