Data rates are measured at worst case condition when all 8 channels are switching at the same time. Data rate is

guaranteed based on the condition that output I/O signal rise/fall time is less than 15% of period of input I/O signal; input I/O

signal is at 50% duty-cycle and output I/O signal duty-cycle deviation is less than 50% ± 10%.
