NOTES: 1. Absolute Maximum Rating Indicates limit beyond which damage to the device may occur. 2. Operating Ratings indicate conditions for which the device is functional but do not guarantee specific performance limits. For guaranteed specifications and test conditions, See the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. 3. VCC supply pin22 must be externally wired to gether to prevent internal damage during VCC power on/off cycles.
