Notes:
1. These are the values at the minimum cycle time. Since the currents are transient, these values decrease as the cycle time
increases. Also note that a bypass capacitor of at least 0.01 µF should be inserted between Vdd and Vss for each memory
chip to suppress power supply voltage noise (voltage drops) due to these transient currents.
2. Idd1 and Idd4 depend on the output load. The maximum values for Idd1 and Idd4 are obtained with the output open state.
