Notes
6. Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output loading of the specified
IOL/IOH and 30-pF load capacitance.
7. tPOWER gives the minimum amount of time that the power supply should be at typical VCC values until the first memory access can be performed.
8. tHZOE, tHZCE,tHZBE and tHZWE are specified with a load capacitance of 5 pF as in part (c) of AC Test Loads. Transition is measured when the outputs enter a high
impedance state.
9. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, tHZBE is less than tLZBE, and tHZWE is less than tLZWE for any
given device.
