Stresses in excess of those listed above may result in permanent damage. These are stress ratings only, and operation at these
levels is not implied. Frequent or extended exposure to absolute maximum conditions may affect device reliability.
Voltage referenced to VSS.
RAM power dissipation (IDDSB + IDDOP) plus RAM output driver power dissipation due to external loading must not exceed this
specification.
Class 2 electrostatic discharge (ESD) input protection. Tested per MIL-STD-883, Method 3015 by DESC certified lab.
