Analog Integrated Circuit Device Data
Freescale Semiconductor
SO (Low-to-High) is for an output with internal conditions such that
the low-to-high transition of CS causes the SO output to switch from
high to low.
1. SO (high-to-low) waveform is for SO output with internal conditions such
2. SO (low-to-high) waveform is for SO output with internal conditions such

that SO output is low except when an output is disabled as a result of de-
tecting a circuit fault with CS in a High Logic state, e.g. open load.
