14. An input setup and hold time derating table is used to increase t
IS
and t
IH
in the case where the input slew
rate is below 0.5 V/ns.
15. An input setup and hold time derating table is used to increase t
DS
and t
DH
in the case where the I/O slew rate
is below 0.5 V/ns.
16. An I/O Delta Rise, Fall Derating table is used to increase t
DS
and t
DH
in the case where DQ, DM, and DQS
slew rates differ.

to V
IL (AC)
or V
IH (DC)
to V
IL (DC)
, similarly for rising
transitions.
2. These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on each device.

1. Input slew rate is based on the lesser of the slew rates determined by either V
IH (AC)
to V
IL (AC)
or V
IH (DC)
to V
IL (DC)
, similarly for rising
transitions.
2. Input slew rate is based on the larger of AC to AC delta rise, fall rate and DC to DC delta rise, fall rate.
3. The delta rise, fall rate is calculated as: [1/(slew rate 1)] - [1/(slew rate 2)]
For example: slew rate 1 = 0.5 V/ns; slew rate 2 = 0.4 V/ns
Delta rise, fall = (1/0.5) - (1/0.4) [ns/V]
= -0.5 ns/V
Using the table above, this would result in an increase in t
DS
and t
DH
of 100 ps.
