Notes: 1. AC measurement assumes tT = 0.5ns. Reference level for timing of input signals is 1.4V(EDS6416AH)
and 1.2V (EDS6416CH).
2. Access time is measured at 1.4V(EDS6416AH) and 1.2V (EDS6416CH). Load condition is CL = 30pF.
3. tLZ (min.) defines the time at which the outputs achieves the low impedance state.
4. tHZ (max.) defines the time at which the outputs achieves the high impedance state.
