SO (low–to–high) is for an output with internal conditions such that
the low–to–high transition of CSB causes the SO output to switch
from high–to–low.

NOTES
: 1. SO (high–to–low) waveform is for SO output with internal
conditions such that SO output is low except when an output is
disabled as a result of detecting a circuit fault with CSB in a
High Logic state (e.g., open load).
2.SO (low–to–high) waveform is for SO output with internal
conditions such that SO output is high except when an output
is disabled as a result of detecting a circuit fault with CSB in
a High Logic state (e.g., shorted load).
