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.

■ Recommended Reflow

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.

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.
