Notes
3. Stresses greater than listed can impair the life of the device.
4. This product is sold in die form so operating conditions are specified for the die, or junction temperature.
5. This part was characterized in a 20-pin SOIC package with external crystal, Electrical Characteristics can change with other package types.
6. If external reference is used, it is required to stop the reference (set reference to LOW) during power down.
