(1) The HD3SS0001 can tolerate polarity inversions for the differential signals denoted by the (p) and (n) terminology to ease potential
board routing issues.The LSTx/LSRx cannot be swapped since they are buffered and therefore uni-directional. Also, note the integrated
pullup on TBC-18 and the integrated pulldown on TBC-16 cannot be swapped.
