(See RNF-VG characteristic.) IC usage notes 1. Maximum ratings If the IC is used in the vicinity of the maximum ratings, even a slight variation in conditions may cause the maximum ratings to be exceeded, thereby leading to breakdown. Allow an ample margin of variation for supply voltage, etc. and use the IC in the range where the maximum ratings are not exceeded. Pin-to-pin short If power is applied when the space between pins is shorted, breakdown or deterioration may occur. When mounting the IC on the board or applying power, make sure that the space between pins is not shorted with solder, etc. Radio applications For use in radio applications, keep a good distance between IC and bar antenna. Printed circuit pattern When designing the printed circuit pattern, make the power supply, output, and ground lines thicker and shorter and determine the pattern and parts placement so that no feedback loop is formed between input and output. Place power capacitor C6, oscillation blocking capacitor C3 as close to the IC pin as po
