8. Handling Precautions

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 Cypress semicon-

ductor devices.

8.1 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 certain established limits, called absolute maximum ratings. Do not exceed these ratings.

• Recommended Operating Conditions

Recommended operating conditions are normal operating ranges for the semiconductor device. All the device's

electrical characteristics are warranted when operated within these ranges.

Always use semiconductor devices within the recommended operating conditions. 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 sales representative before-

hand.

• 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
