Note
24.Unless otherwise noted, test conditions are based on signal transition time of 2V/ns, timing reference levels of 0.75V, Vref = 0.75V, RQ = 250Ω, VDDQ = 1.5V, input
pulse levels of 0.25V to 1.25V, and output loading of the specified IOL/IOH and load capacitance shown in (a) of AC Test Loads and Waveforms.
