●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.

●Description of BU4021B series model
Function: 8-stage static shift register
1)Description of operation
BU4021B is an 8-bit static shift register capable of parallel input/series output and series input/series output. In parallel
operation, DS (data) being asynchronous with the clock is inputted into each F/F and obtained at output.
In series operation, DS (data) is triggered by clock.
When P/S input level is “H”, parallel operation is effective, and when P/S input level is “L”, series operation is effective.

●Description of BU4094BC series model
Function: Dual 4-bit static shift register
1)Description of operation
BU4094BC is an 8-stage shift/store register provided in each stage with a data latch with 3-state output. 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.

●Description of BU4538B series model
Function: Dual high accuracy monostable multivibrator
1)Description of operation
BU4538B is a re-triggerable monostable multi vibrator. 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.)

●Notes for use
1. 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
