The BU2090, BU2090F, BU2090FS, BU2092, BU2092F, and BU2092FV are 12-bit serial input, parallel output
drivers.
For the BU2090 / F / FS, data input is shifted to the 12-bit internal shift register on the rising edge of a clock pulse.
On the falling edge of the pulse, if the DATA pin is HIGH, the data in the shift register is output in parallel to Q0 to
Q11.
For the BU2092 / F / FV, shift data read at the rising edge of CLOCK is output in parallel to Q0 to Q11 at the rising
edge of LCK. These ICs also have an OE pin, which when HIGH, forces data to be output, regardless of the shift
data state.

Q0 to Q11 output for the BU2090 / F / FS and BU2092 / F / FV is Nch open drain output. When the shift register transfer data is LOW,
the corresponding output FET is ON (continuous state). When the transfer data is HIGH, the output FET is OFF (discontinuous).

operation
•TheCircuit
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.

For the BU2092 / F / FV
The content of the 12-bit shift register is stored in the 12-bit storage register at the rising edge of LCK, and is output
to the corresponding Q0 to Q11. When OE is HIGH, regardless of the content of the storage register, the output FET
turns OFF and enters a HIGH (discontinuous) state.
