General-purpose CMOS Logic IC Series (BU4S,BU4000B Series) High Voltage CMOS Logic ICs <Function Logic> BU4015B,BU4015BF,BU4021B,BU4021BF, BU4094BC,BU4094BCF,BU4094BCFV,BU4538B,BU4028B No.09050EAT04 ●Description BU4015B series ICs are 4-stage static shift registers, each consisting of 2 circuits. The D flip-flops of each stage share a common reset input, enabling asynchronous reset at any time. BU4021B series ICs are 8-bit static shift registers configured with 8 register cells, each of which has parallel input. Control of the parallel/serial input (P/S) enables serial input/output with clock synchronization and well as parallel input/serial output conversions. BU4094BC series ICs are shift/store registers, each consisting of an 8-bit shift register and an 8-bit latch. Output can be held in the data transfer mode because the data read into the shift register can be latched by the asynchronous strobe input, The BU4538B IC is a monostable multivibrator that can be reset and retriggered from either edge of an input pulse. A wide range of accurate output pulse widths is available because the output pulse width and accuracy are determined by the external timing constants Cx an Rx. The BU4028B IC is a decoder which converts BCD signals into decimal signals. Of the 10 outputs (Q0 ~ Q9), those corresponding to the input codes A-D are set to “H”, while the others are set to “L”. ●Features 1) Low power consumption 2) Wide operating supply voltage range 3) High impedance 4) High fan out 5) L-TTL2 and LS-TTL1 inputs can be driven directly. ●Applications BU4015B: serial / parallel data conversion and ring counter. BU4021B: control circuits, timing circuits and as a general purpose register requiring high degree of noise tolerance. BU4094BC: series/parallel data conversion and data receivers. BU4538B: can obtain the output pulse amplitude with improved accuracy by external capacity and resistance. BU4028B: code conversion, address decoding, memory selection control, demultiplexing or readout and decoding, etc. ●Lineup High VoltageCMOS Logic <Function Logic> www.rohm.com © 2009 ROHM Co., Ltd.

Each register is provided with an independent clock and reset input having one series data input. Register state is the D type master/slave flip-flop. Data is shifted to the next stage during the rise time of the clock. Each register can be cleared by addition of “H” level to reset.

Data read into shift register is read into the latch during the fall time of asynchronous STROBE input, and in the data transfer mode, output can be held. Data is passed through the latch and outputted when the STROBE is in “H” level. Because the parallel output becomes high impedance when the OUTPUT ENABLE terminal is set to “L” level by 3-state, the parallel output can be connected directly with the 8-bit pass line.

Triggering is possible from either edge of the rise time and fall time of input pulse. Output pulse setting is determined by the time constant (Rx · Cx) of external Rx and Cx. Recommended output pulse amplitude is 200[μs]~1[s]. (Cautions on use: In case of system power down, etc., electric charge accumulated in the capacity Cx is discharged to the VDD terminal through protective diode of 2 pins of 14 pins. When the electric current due to accumulated electric charge exceeds 10[mA], IC may be destructed. When a large capacity Cx is used, electric current flowing into the IC can be restricted by inserting the diode Dx.)

Absolute maximum ratings An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down the devices, thus making impossible to identify breaking mode, such as a short circuit or an open circuit. If any over rated values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices, such as fuses. 2. Connecting the power supply connector backward Connecting of the power supply in reverse polarity can damage IC. Take precautions when connecting the power supply lines. An external direction diode can be added. 3. Power supply lines Design PCB layout pattern to provide low impedance GND and supply lines. To obtain a low noise ground and supply line, separate the ground section and supply lines of the digital and analog blocks. Furthermore, for all power supply terminals to ICs, connect a capacitor between the power supply and the GND terminal. When applying electrolytic capacitors in the circuit, not that capacitance characteristic values are reduced at low temperatures. 4. GND voltage The potential of GND pin must be minimum potential in all operating conditions. 5. Thermal design Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions. 6. Inter-pin shorts and mounting errors Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any connection error or if pins are shorted together. 7. Actions in strong electromagnetic field Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to malfunction. 8. Testing on application boards When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to stress. Always discharge capacitors after each process or step. Always turn the IC's power supply off before connecting it to or removing it from a jig or fixture during the inspection process. Ground the IC during assembly steps as an antistatic measure. Use similar precaution when transporting or storing the IC. 9. Ground Wiring Pattern When using both small signal and large current GND patterns, it is recommended to isolate the two ground patterns, placing a single ground point at the ground potential of application so that the pattern wiring resistance and voltage variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to change the GND wiring pattern of any external components, either. 10. Unused input terminals Connect all unused input terminals to VDD or VSS in order to prevent excessive current or oscillation Insertion of a resistor (100kΩ approx.) is also recommended www.rohm.com © 2009 ROHM Co., Ltd.
