(Note 8)
Note 6: Absolute Maximum continuous ratings are those values beyond
which damage to the device may occur. Exposure to these conditions or
conditions beyond those indicated may adversely affect device reliability.
Functional operation under absolute maximum rated conditions in not
implied.
Note 7: I

DC Electrical Characteristics (Continued)
Note 9: All typical values are at V
CC
= 3.3V, V
CCQ
= 3.3V, and T
A
= 25°C.
Note 10: GTLP V
REF
and V
TT
are specified to 2% tolerance since signal integrity and noise margin can be significantly degraded if these supplies are noisy.
In addition, V
TT
and Rterm can be adjusted beyond the recommended operating conditions to accommodate backplane impedances other than 50Ω, but
must remain within the boundaries of the DC Absolute Maximum ratings. Similarly V
REF
can be adjusted to optimize noise margin.
Note 11: For conditions shown as Min or Max, use the appropriate value specified under recommended operating conditions.
Note 12: This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
CC
or GND.
AC Operating Requirements
Over recommended ranges of supply voltage and operating free-air temperature, V

= 1.0V (unless otherwise noted).

- Output to output skew is defined as the absolute value of the difference between the actual propagation delay for all outputs
within the same packaged device. The specifications are given for specific worst case V
CC
and temperature and apply to any outputs switching in the same
direction either HIGH-to-LOW (t
OSHL
) or LOW-to-HIGH (t
OSLH
) or in opposite directions both HL and LH (t
OST
). This parameter is guaranteed by design and
statistical process distribution. Actual skew values between the GTLP outputs could vary on the backplane due to the loading and impedance seen by the
device.
Note 15: t
PV
- Part to part skew is defined as the absolute value of the difference between the actual propagation delay for all outputs from device to device.
The parameter is specified for a specific worst case V
CC
and temperature. This parameter is guaranteed by design and statistical process distribution. Actual
skew values between the GTLP outputs could vary on the backplane due to the loading and impedance seen by the device.
Note 16: Due to the open drain structure on GTLP outputs t
OST
and t
PV(LH)
in the A-to-B direction are not specified. Skew on these paths is dependent on the
V
TT
and R
T
values on the backplane.
