NOTE: The data sheet provides timing at the device pin. For output timing analysis, the tester pin electronics and its transmission line effects
must be taken into account. A transmission line with a delay of 2 ns or longer can be used to produce the desired transmission line effect.
The transmission line is intended as a load only. It is not necessary to add or subtract the transmission line delay (2 ns or longer) from
the data sheet timings.
Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at the device pin.

signal transition levels
All input and output timing parameters are referenced to 1.5 V for both “0” and “1” logic levels.
Vref = 1.5 V
Figure 26. Input and Output Voltage Reference Levels for AC Timing Measurements
All rise and fall transition timing parameters are referenced to V_IL MAX and V_IH MIN for input clocks, V_OL MAX
and V_OH MIN for output clocks.
Vref = VIH MIN (or VOH MIN)
Vref = VIL MAX (or VOL MAX)
