Precautions and Handling Devices
7.1
Handling Precautions
All 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, and so on.). This page describes precautions that must be
observed to minimize the chance of failure and to obtain higher reliability from your Cypress semiconductor devices.
7.1.1
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, and so on.) 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 datasheet. Users
considering applications outside the listed conditions are advised to contact their sales representative beforehand.
Processing and Protection of Pins
Follow these precautions when handling the pins, which connect semiconductor devices to power supply and input/output
functions.
1. Preventing overvoltage and overcurrent 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 overcurrent 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.
