2. The rising edge of clock is symbolized by
3. A continue deselect cycle can only be entered if a deselect cycle is executed first.
4. WE = L means Write operation in Write Truth Table.
WE = H means Read operation in Write Truth Table.
5. Operation finally depends on status of asynchronous pins (ZZ and OE).

Notes:
1. X means "Don't Care".
2. For write cycles following read cycles, the output buffers must be disabled with OE, otherwise data
bus contention will occur.
3. Sleep Mode means power Sleep Mode where stand-by current does not depend on cycle time.
4. Deselected means power Sleep Mode where stand-by current depends on cycle time.

Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may 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 specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reli-
ability.
2. This device contains circuity to protect the inputs against damage due to high static voltages or electric fields; however, precau-
tions may be taken to avoid application of any voltage higher than maximum rated voltages to this high-impedance circuit.
3. This device contains circuitry that will ensure the output devices are in High-Z at power up.
