Notes: 1. All voltages are specified relative to V
DD = 0 V.
2. The following relation must be always hold
V
DD ≥ V1 ≥ V2 ≥ V3 ≥ V4 ≥ V5
3. Exceeding the absolute maximum ratings may cause permanent damage to the device. Functional
operation under these conditions is not implied.
4. Moisture resistance of flat packages can be reduced by the soldering process, so care should be taken to
avoid thermally stressing the package during board assembly.
