Precautions for Use
■ Correct Use
• The absolute maximum rating is the limit value which should not be
exceeded even in a flash. Exceeding this value can cause deterio-
ration of the characteristics or complete failure of the IC.
• Check the operation at the communication frequency to be used
before using the device.
• Sufficiently take into consideration the static electricity, chattering
and voltage of the input to be connected when determining each
input circuit.
• Although the device contains an ESD protection circuit, static elec-
tricity that exceeds the function may damage the device. When
handling the device, exercise due caution by, for example, ground-
ing the human body.
• Due to potential damage, do not use product that has been
dropped or that has come into contact with water.
■ RoHS Directive Compliance
Models that are indicated as being RoHS compliant are free of the
following six substances.
Lead:
1,000 ppm max.
Mercury:
1,000 ppm max.
Cadmium:
100 ppm max.
Hexavalent chromium:
1,000 ppm max.
PBB:
1,000 ppm max.
PBDE:
1,000 ppm max.

Conditions
Allowable Temperature Profile Conditions
Product mounting method should be by Reflow and we recommend
the following temperature profile. Reflow no more than two times,
maximum.
260°C (max)

60s (max)
Time
Storage Conditions before Mounting
Moisture absorption by the plastic package will increase the possibil-
ity of faults, such as cracks; therefore, take enough care for storage.
