A 50Ω 4/4 ●Cautions for use (1) Absolute maximum ratings If the absolute maximum ratings for applied voltage and/or operation temperature are exceeded, LSI damage may result. Therefore, do not apply voltage or use in a temperature that exceeds these absolute maximum ratings. If it is possible that absolute maximum ratings will be exceeded, use a physical safety device such as a fuse and make sure that no conditions that might exceed the absolute maximum ratings will be applied to the LSI IC. (2) GND potential Regardless of the operation mode, the voltage of the GND pin should be at least the minimum voltage. Actually check whether or not the voltage at each pin, including transient phenomena, is less than the GND pin voltage. (3) Thermal design The thermal design should be done using an ample margin that takes into consideration the allowable dissipation under actual use conditions. (4) Shorts between pins and mounting errors When mounting LSI ICs onto the circuit board, make sure each LSI's orientation and position is correct. The ICs may become damaged if they are not mounted correctly when the power is turned on. Similarly, damage may also result if a short occurs, such as when a foreign object is positioned between pins in an IC, or between a pin and a power supply or GND connection. (5) Operation in strong electromagnetic field When used within a strong electromagnetic field, evaluate carefully to avoid the risk of operation faults. (6) Frequency response About frequency response in f＞10MHz, refer to technical note. REV.
