BU2090 / BU2090F / BU2090FS / Standard ICs 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 Radio cassette players, telephones, compact audio systems, car stereos, and others Features 1) Low power dissipation. 5) Diverse variety of packages. 2) Operating voltages ranging from 2.7 to 5.5V. BU2090 / F / FS: DIP16, SOP16, SSOP-A16 3) Output is Nch open drain. BU2092 / F / FV: DIP18, SOP18, SSOP-A18 4) High output withstand voltage of + 25V. (plastic molds) 6) High drive capability direct lighting of green LED possible. 1BU2090 / BU2090F / BU2090FS / Standard ICs BU2092 / BU2092F / BU2092FV Absolute maximum ratings (Ta = 25C) (BU2090 / F / FS, BU2092 / F / FV) Parameter Symbol Limits Unit Power supply voltage VDD 0.3 ~ + 7.0 V 1 * 1000 (DIP), 300 (SOP), 500 (SSOP) BU2090 / F / FS Power Pd mW * 1 dissipation BU2092 / F / FV 1050 (DIP), 450 (SOP), 400 (SSOP) * 2 * 3 BU2090 / F / FS 500 (SOP) , 650 (SSOP) Power Pd mW dissipation * 2 * 4 BU2092 / F / FV 500 (SOP) , 650 (SSOP) Operating temperature Topr 25 ~ + 75 C Storage temperature Tstg 55 ~ + 125 C Input voltage VIN VSS 0.3 ~ VDD + 0.3 V Output voltage VO VSS ~ 25.0 V 1 Unmounted * 2 When mounted on a glass epoxy board of 50mm 50mm 1.6mm * 3 When mounted on a glass epoxy board of 90mm 50mm 1.6mm * 4 When mounted on a glass epoxy board of 70mm 70mm 1.6mm * Recommended operating conditions Parameter Symbol Limits Unit Power supply voltage VDD 2.7 ~ 5.5 V 2
