1 General-purpose CMOS Logic IC Series (BUS,BUB Series) High Voltage CMOS Logic ICs <Logic Gate> BUB/F,BUB/F/FV,BUB/F,BU7B/F, BUB/F/FV,BU9B/F/FV,BU9UB/F/FV,BUB/F/FV No.9EAT Description BUB series ICs are -input positive logic NOR gates, each with four built-in circuits. A buffer achieved by an inverter added at the gate output improves the input / output propagation characteristics and minimizes variation in the propagation time caused by an increase in the load capacitance. BUB series ICs are -input positive logic NAND gates. Four circuits are contained on a single chip. An inverter-based buffer is included at the gate output, enabling improved input / output propagation characteristics, and an increased load capacitance minimizes fluctuations in the propagation time. BUB and BU7B series ICs are exclusive OR gates, each with four built-in circuits. An inverter-based buffer was incorporated at the gate output for enhanced I/O voltage characteristics, and the load capacitance has been increased in order to minimize fluctuations in the propagation time. BUB series are -input positive logic AND gates with four circuits mounted on a single chip. An inverter-type buffer was added to the gate output, improving input/output transmission speed, and an increased load capacitance suppresses fluctuations in the transmission time. BU9B series ICs are -circuit, -input NAND gates whose input pins all have a Schmitt trigger function. BU9UB series ICs are -circuit inverters with no buffers. A single-stage gate configuration reduces propagation time. BUB series ICs are inverter-type Schmitt trigger circuits, each incorporating circuits in a single chip. Features ) Low power consumption ) Broad operating supply voltage range: V to V ) High input impedance ) High fan out ) L-TTL and LS-TTL inputs can be directly driven ) All outputs are equipped with buffers (except for BU9UB) Applications These products are suitable for applications requiring low power consumption and a high degree of noise tolerance The BUB/BU7B series can be used in digital comparators and parity circuits The BU9B series are suitable as line receivers, waveform shaping and multi-vibrators, etc. The BUB series can be used in waveform shaping circuits for inputs with a slow rise time and fall time Lineup High Voltage CMOS Logic Logic Gate circuits circuits circuits NOR gate NAND gate EXOR gate BUB/ BUF BUB/ BUB F/ BUB FV BUB/ BUB F (Quad -input NOR gate) (Quad -input NAND gate) (Quad exclusive OR gate) circuits circuits circuits circuits circuits EXOR gate AND gate NAND gate INV gate INV gate BU7B/ BU7B F BUB/ BUF/ BUFV BU9B/ BU9B F/ BU9B FV BU9UB/ BU9UB F/ BU9UB FV BUB/ BUBF/ BUBFV (Quad exclusive OR gate) (Quad -input AND gate) (Quad -input NAND Schmitt trigger) (Hex inverter) (Hex Schmitt trigger inverter) 9 ROHM Co., Ltd.

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.. 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.. 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.. GND voltage The potential of GND pin must be minimum potential in all operating conditions.. Thermal design Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions.. 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.. 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.. Unused input terminals Connect all unused input terminals to VDD or VSS in order to prevent excessive current or oscillation. Insertion of a resistor (kω approx.) is also recommended 9 ROHM Co., Ltd.
