| Standard ICs BU2090 / BU2090F / BU2090FS / BU2092 / BU2092F / BU2092FV 12-bit, serial IN, parallel OUT driver BU2090 / BU2090F / BU2090FS / BU2092 / BU2092F / BU2092FV 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. *Applications players, telephones, compact audio systems, car stereos, and others Radio cassette *Features dissipation. 1) Low power 2) Operating voltages ranging from 2.7 to 5.5V. 3) Output is Nch open drain. 4) High output withstand voltage of + 25V. 5) Diverse variety of packages.

Subsequently, it The logic of the DATA 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.

When OE is HIGH, regardless of the content of the storage register, the output FET turns OFF and enters a HIGH (discontinuous) state.
