NOTES:

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

2. Reference AC Operating Conditions and Characteristics for Input and Timing.

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

4. Data states are all zero.

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

6. CMOS levels for I/O’s are VIT ≤ VSS + 0.2 V or ≥ VDDQ – 0.2 V. CMOS levels for other inputs are Vin ≤ VSS + 0.2 V or ≥ VDD – 0.2 V.

7. TTL levels for I/O’s are VIT ≤ VIL or ≥ VIH2. TTL levels for other inputs are Vin ≤ VIL or ≥ VIH.
