■ PRECAUTIONS FOR HANDLING THE DEVICES

Any semiconductor devices have inherently a certain rate of failure. The possibility of failure is greatly affected

by the conditions in which they are used (circuit conditions, environmental conditions, etc.). This page describes

precautions that must be observed to minimize the chance of failure and to obtain higher reliability from your

FUJITSU MICROELECTRONICS semiconductor devices.

Precautions for Product Design

This section describes precautions when designing electronic equipment using semiconductor devices.

• Absolute Maximum Ratings

Semiconductor devices can be permanently damaged by application of stress (voltage, current, temperature,

etc.) in excess of absolute maximum ratings. Do not exceed these ratings.

• Recommended Operating Conditions

The recommended operating conditions are required in order to ensure the normal operation of the semicon-

ductor device. All of the device’s electrical characteristics are warranted when the device is operated within these

ranges.

Always use semiconductor devices within their recommended operating condition ranges. Operation outside

these ranges may adversely affect reliability and could result in device failure.

No warranty is made with respect to uses, operating conditions, or combinations not represented on the data

sheet. Users considering application outside the listed conditions are advised to contact their representatives

beforehand.

• Processing and Protection of Pins

These precautions must be followed when handling the pins which connect semiconductor devices to power

supply and input/output functions.

(1) Preventing Over-Voltage and Over-Current Conditions

Exposure to voltage or current levels in excess of maximum ratings at any pin is likely to cause deterioration

within the device, and in extreme cases leads to permanent damage of the device. Try to prevent such

overvoltage or over-current conditions at the design stage.

(2) Protection of Output Pins

Shorting of output pins to supply pins or other output pins, or connection to large capacitance can cause

large current flows. Such conditions if present for extended periods of time can damage the device.

Therefore, avoid this type of connection.

(3) Handling of Unused Input Pins

Unconnected input pins with very high impedance levels can adversely affect stability of operation. Such pins

should be connected through an appropriate resistance to a power supply pin or ground pin.
