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:

1. A nominal 2.5V peak-to-peak input pulse level is specified to allow consistent, repeatable results in automatic test equipment (ATE) environment. Compliant

2. A nominal 1.25V crossing point level is specified to allow consistent, repeatable results in an automatic test equipment (ATE) environment. Compliant devices

3. In all cases, input waveform timing is marked at the differential cross-point of the input signals.

4. The input signal edge rate of 2.5V/nS or greater is to be maintained in the 20% to 80% range of the input waveform.
