NOTES:
1. Parameters are valid over specified temperature range.
2. All voltage measurements are referenced to ground (GND). For testing, all inputs except X1/CLK swing between 0.8V and 2.0V with a
transition time of 20ns maximum. For X1/CLK, this swing is between 0.4V and 2.4V. All time measurements are referenced at input voltages
of 0.4V and 2.4V and output voltages of 1.2V and 2.0V, as appropriate.
3. See Figure 17 for test conditions for outputs.
4. Tests for open drain outputs are intended to guarantee switching of the output transistor. Measurement of this response is referenced from
midpoint of the switching signal to a point 0.2V above the actual output signal level. This point represents noise margin that assures true
switching has occurred.
