Cautions 1.

2.

Ensure that the pin voltage does not exceed the power supply voltage.

With this application circuit, confirm that there is not problem with interfering wave

characteristics.

Remark The VCC pass capacitors (1 µF, 1000 pF) should be located close to the respective VCC pins.

Chip laminated ceramic capacitors (MURATA GRM36 or equivalent) should be used.
