8. If
WE
is low or the
WE
low transition occurs prior to or simultaneously with the
CE
low transition,
the output buffers remain in a high-impedance state during this period.
9. Each DS1225Y is marked with a 4-digit date code AABB. AA designates the year of manufacture.
BB designates the week of manufacture. The expected t
DR
is defined as starting at the date of
manufacture.
10. All AC and DC electrical characteristics are valid over the full operating temperature range. For
commercial products, this range is 0°C to 70°C. For industrial products (IND), this range is -40°C to
+85°C.
11. In a power down condition the voltage on any pin may not exceed the voltage on V
CC
.
12. t
