Description

The BU2090, BU2090F, 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.
