NOTES:

1. LBO pin has an internal pullup and will exhibit leakage currents of ± 5 µA.

2. Reference AC Operating Conditions and Characteristics for input and timing (VIH/VIL, tr / tf, pulse level 0 to 3.0 V).

3. All addresses transition simultaneously low (LSB) and then high (MSB).

4. Data states are all zero.

5. Device in Deselected mode as defined by the Truth Table.
