Notes:
1. I_OH = (V_DDQ/2) / (RQ/5) +/– 15% @ V_OH = V_DDQ/2 (for: 175Ω ≤ RQ ≤ 350Ω).
2. I_OL = (V_DDQ/2) / (RQ/5) +/– 15% @ V_OL = V_DDQ/2 (for: 175Ω ≤ RQ ≤ 350Ω).
3. Parameter tested with RQ = 250Ω and V_DDQ = 1.5 V or 1.8 V
4. 0Ω ≤ RQ ≤ ∞Ω
5. I_OH = –1.0 mA
6. I_OL = 1.0 mA

Notes:
1. Power measured with output pins floating.
2. Minimum cycle, I_OUT = 0 mA
3. Operating current is calculated with 50% read cycles and 50% write cycles.
4. Standby Current is only after all pending read and write burst operations are completed.
