GTLP10B320
DC Electrical Characteristics (Continued)
Note 7: All typical values are at V
CC
= 3.3V and T
A
= 25°C.
Note 8: For conditions shown as Min, use the appropriate value specified under recommended operating conditions.
Note 9: This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
CC
or GND.
Note: 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 R
TERM
can be adjusted beyond the recommended operating 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.
AC Operating Requirements
Over recommended ranges of supply voltage and operating free-air temperature, V
REF
= 1.0V (unless otherwise noted).
