•
The logic of the DATA pin is sent to the 12-bit shift register on the rising edge of the CLOCK pulse. Subsequently, it
is shifted from Q0 to Q11 for every clock rising edge.
For the BU2090 / F / FS
When the DATA pin is LOW on the CLOCK falling edge, the data does not change its output state. It is only shifted in
the internal shift register. However, when the DATA pin is HIGH, the content of the 12-bit shift register is latched and
is output to the corresponding Q0 to Q11.
