AC CHARACTERISTICS
ECL input values are -0.9 to -1.7V, with input rise/fall times ≤ 2ns,
measured between the 20% and 80% points. Timing reference
points at 50% for inputs and outputs.
OUT and OUT loading with 50Ω to -2.0V. Typical values are
based on nominal temperature, i.e., and nominal voltage, i.e.,
-5.2V.
