Product Specification
R
Input/Output Individual Options
Each device pad has optional pull-up and pull-down resis-
tors in all SelectI/O-Ultra configurations. Each device pad
has an optional weak-keeper in LVTTL, LVCMOS, and PCI
SelectI/O-Ultra configurations, as illustrated in
Figure 6
.
Values of the optional pull-up and pull-down resistors are in
the range 10 - 60 K
, which is the specification for V
CCO
when operating at 3.3V (from 3.0V to 3.6V only). The clamp
diode is always present, even when power is not.
