NOTES:

1. These power consumption characteristics are for all the valid input interfaces and cover the worst case input and output interface combinations.

2. The termination resistors are excluded from these measurements.

3. If the differential input interface is used, the true input is held LOW and the complementary input is held HIGH.

NOTES:

2. A nominal 900mV timing measurement reference level is specified to allow constant, repeatable results in an automatic test equipment (ATE) environment.

3. The input signal edge rate of 2V/ns or greater is to be maintained in the 10% to 90% range of the input waveform.
