7.2 Handling Precautions

Never exceed the absolute maximum ratings, even for a very short time.
Take precautions against the influence of heat in the environment, keeping the temperature around the Commander core as cool as possible.
Please note that ignoring the following may result in latching up and may cause overheating and smoke.

Do not apply a voltage greater than the absolute maximum rating voltage. Please consider the voltage drop timing when turning the power ON/OFF.
Be careful not to introduce external noise into the Commander core.
Hold the unused input terminals to +3.3V or GND level.
Do not short-circuit the outputs.
Protect the LSI from inductive pulses caused by electrical sources that generate large voltage surges, and take appropriate precautions against static electricity.

Provide external circuit protection components so that overvoltage caused by noise, voltage surges, or static electricity is not fed to the Commander core.

Always handle carefully and keep in their packages. Throwing or dropping may damage them.
Do not store in a location exposed to water droplets or direct sunlight.
Do not store in a location where corrosive gases are present, or in excessively dusty environments.
Store in an anti-static storage container, and make sure that no physical load is placed on the Commander cores.

In order to prevent damage caused by static electricity, pay attention to the following:

Make sure to ground all equipment, tools, and jigs that are present at the work site.
Ground the work desk surface using a conductive mat or similar apparatus (with an appropriate resistance factor). Do not allow work on a metal surface, which can cause a rapid change in the electrical charge due to extremely low resistance.
When using a vacuum device, provide anti-static protection using a conductive rubber pickup tip. Anything that comes in contact with the leads should have as high a resistance as possible.
When using a pincer that may make contact with any terminals, use an anti-static model. Do not use a metal pincer, if possible.
Store unused Commander cores in a PC-board storage box that protects against static electricity, and make sure there is adequate clearance between the Commander cores. Never directly stack them on each other, as it may cause friction that can develop an electrical charge.

Operators must wear wrist straps that are grounded through approximately 1M-ohm of resistance.
Use low voltage soldering devices and make sure the tips are grounded.
Do not store or use Commander cores near high-voltage electrical fields, such those produced by a CRT.
Please avoid soldering in a soaking method so as to prevent a dramatic change of temperature to the package and damage to the device.

The package is made from flame retardant material but may burn. When baked or burned, it may generate gases or fire. Do not use it in the proximity of ignition sources or flammable objects.
The Commander core is designed for use in commercial apparatus (office machines, communication equipment, measuring equipment, and household appliances). If you use it in any device that may require high quality and reliability, or where faults or malfunctions may directly affect human injury/survival (such as in nuclear power control devices, aviation devices or spacecraft, traffic signals, fire control, or various types of safety devices), we will not be liable for any problem that occurs, even if it was directly caused by the Commander core. Customers must provide their own safety measures to ensure appropriate performance in all circumstances.
