The output current value can be set using an external resistor. As a result, all outputs will have virtually the same current levels. This driver incorporates bit constant-current outputs, a bit shift register, a bit latch and a bit AND-gate circuit. The suffix G appended to the part number represents a Lead Pb -Free product. Please take care when wiring the output terminals, the power supply terminal and the GND terminals. In order to ensure that the level of the power supply voltage is correct, an external resistor must be connected between R-EXT and GND.
Be careful because it is not triggered-latch circuit. When it is pulled Low, data is latched. And are turned on, when the terminal is driven Low. This regulated the output current. AFG-Type: Powers dissipation is derated by 6. Max 5. Please consider the timings carefully. It is the one way of being effective to build in the r3 in this problem. Though the resistance parts increase, the fixed constant current performance is kept Example TD62MF: 8-bit multi-chip PNP transistor array, which is not used in static lighting system.
If overvoltage is caused by inductance between the LED and the output terminals, both the LED and the terminals may suffer damage as a result. There is only one GND terminal on this device when the inductance in the GND line and the resistor are large, the device may malfunction due to the GND noise when output switchings by the circuit board pattern and wiring.
Fluctuation in the output waveform is likely to occur when the GND line is unstable or when a capacitor of more than 50 pF is used. Therefore, take care when designing the circuit board pattern layout and the wiring from the controller. This application circuit is a reference example and is not guaranteed to work in all conditions.
Be sure to check the operation of your circuits. This device does not include protection circuits for overvoltage, overcurrent or overtemperature. If protection is necessary, it must be incorporated into the control circuitry. The device is likely to be destroyed if a short-circuit occurs between either of the power supply pins and any of the output terminals when designing circuits, pay special attention to the positions of the output terminals and the power supply terminals VDD and VLED , and to the design of the GND line.

IC Usage Considerations Notes on Handling of ICs 1 The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded, even for a moment. Do not exceed any of these ratings. Exceeding the rating s may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion. The IC will fully break down when used under conditions that exceed its absolute maximum ratings, when the wiring is routed improperly or when an abnormal pulse noise occurs from the wiring or load, causing a large current to continuously flow and the breakdown can lead smoke or ignition.
To minimize the effects of the flow of a large current in case of breakdown, appropriate settings, such as fuse capacity, fusing time and insertion circuit location, are required.
If your design includes an inductive load such as a motor coil, incorporate a protection circuit into the design to prevent device malfunction or breakdown caused by the current resulting from the inrush current at power ON or the negative current resulting from the back electromotive force at power OFF.
IC breakdown may cause injury, smoke or ignition. Use a stable power supply with ICs with built-in protection functions. If the power supply is unstable, the protection function may not operate, causing IC breakdown. Do not insert devices in the wrong orientation or incorrectly. Make sure that the positive and negative terminals of power supplies are connected properly. Otherwise, the current or power consumption may exceed the absolute maximum rating, and exceeding the rating s may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion.
In addition, do not use any device that is applied the current with inserting in the wrong orientation or incorrectly even just one time. If there is a large amount of leakage current such as input or negative feedback condenser, the IC output DC voltage will increase.
If this output voltage is connected to a speaker with low input withstand voltage, overcurrent or IC failure can cause smoke or ignition. The over current can cause smoke or ignition from the IC itself. These ICs generate heat even during normal use. In addition, please design the device taking into considerate the effect of IC heat radiation with peripheral components.
To avoid this problem, take the effect of back-EMF into consideration in system design. Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress.
