NOTES:
1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are
exceeded. Functional operation should be restricted to RECOMMENDED OPER-
ATING CONDITIONS. Exposure to higher than recommended voltages for extended
periods of time could affect device reliability.
2. All voltages are referenced to VSS.
3. Power dissipation capability will be dependent upon package characteristics and use
environment. See Package Thermal Characteristics.
4. Consult Junction to Ambient Thermal Characteristics table for details and conditions.

NOTES:
1. RAM junction temperature is a function of on–chip power dissipation, package thermal impedance, mounting site temperature, and
mounting site thermal impedance.
2. Per SEMI G38–87.
3. Indicates the average thermal impedance between the die and the mounting surface.
4. Indicates the average thermal impedance between the die and the case top surface. Measured via the cold plate method (MIL SPEC–883
Method 1012.1).
This device contains circuitry to protect the
inputs against damage due to high static volt-
ages or electric fields; however, it is advised
that normal precautions be taken to avoid appli-
cation of any voltage higher than maximum
rated voltages to this high–impedance circuit.
