Notes on Using the IC
• Maximum ratings
When this IC is used near its maximum ratings, it is possible that a slight fluctuation in the operating conditions could
cause the maximum ratings to be exceeded, damaging the IC. Therefore, allow for an adequate safety margin in
regards to supply voltage, etc., so that the IC is never used under conditions that exceed its maximum ratings.
• Short circuit between pins
Applying power to the IC while a short circuit exists between two pins can cause damage or deterioration in the IC.
Therefore, after mounting the IC on a board, make sure that there are no solder bridges, etc., causing a short circuit
between any of the pins before applying power to the IC.
• Using the IC in a radio
When using this IC in a radio, make sure that there is enough distance between the IC and the bar antenna.
• Printed circuit pattern
When designing the printed circuit pattern, keep power, output, and ground lines thick and short, and determine the
placement of the pattern and the components in such a way as to prevent the generation of an I/O feedback loop.
In addition, power supply capacitor C6 and oscillation blocking capacitor C5 should be placed as close as possible to
the IC pins in order to prevent oscillation.
