V
Note 1: V
IL
is defined as the voltage at which the output (DATA/IO) voltage equals 0.5V.
Note 2: V
IH
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 DV
CC
. Input and output levels are measured at 50% of the waveform.
Note 5: Specifications to -40°C are guaranteed by design, not production tested.
