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 VCC or GND.
Note: GTLP VREF and VTT are specified to 2% tolerance since signal integrity and noise margin can be significantly degraded if these supplies are noisy. In
addition, VTT and RTERM 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, VREF can be adjusted to optimize noise margin.
AC Operating Requirements
Over recommended ranges of supply voltage and operating free-air temperature, VREF = 1.0V (unless otherwise noted).
