Figure 11. Timing diagram
LE and OE are level sensitive and not synchronized with the CLK signal
When LE is at low level, the latch circuit holds previous data
If LE is high level, data present in the shift register are latched
When OE is at low level, the status of the outputs OUT0 to OUT15 depends on the data
in the latch circuits
With OE at high level, all outputs are switched off independently on the data stored in
the latch circuits
Every rising edge of the CLK signal, a new data on SDI pin is sampled. This data is
loaded into the shift register, whereas a bit is shifted out from SDO.
