Note 1: VIL is defined as the voltage at which the output (DATA/IO) voltage equals 0.5V.

Note 2: VIH is defined as the voltage at which the output (DATA/IO) voltage exceeds the input (IO/DATA) voltage by 100mV.

Note 3: Timing specifications are guaranteed by design, not production tested.

Note 4: The maximum CLK frequency is defined as the output duty cycle remaining in the 40% to 60% range when the 50% CIN is

applied. CIN has 5ns rise and fall times; levels are GND to DVCC. Input and output levels are measured at 50% of the waveform.

Note 5: Specifications to -40°C are guaranteed by design, not production tested.
