The data rate is guaranteed based on the condition that the output I/O signal rise/fall time is less than 15% of the input I/O
signal period; the input I/O signal is at 50% duty cycle and the output I/O signal duty cycle deviation is not less than 30%.
Note that the Rup of 4.7 kΩ is an effective R pull-up value. Since the device has an integrated 10 kΩ pull-up resistor, an
effective value of 4.7 k
Ω is obtained by adding an external 8.9 kΩ pull-up resistor.
