Note:
Stresses greater than those listed in this table can cause permanent damage to the device. This is a stress rating only and functional operation of
the device at these or any other conditions above those indicated in the operational sections of this datasheet is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.

Notes:
1. IOUT = chip output current.
2. The numeric suffix indicates the part operating at speed, as indicated in AC Timing Characteristics table (that is, IDD25 indicates 2.5ns cycle
time).
3. ODT must be disabled.
4. Balls with ODT and DOFF# do not follow this spec, ILI = ±5uA.
