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. At any given temperature and voltage condition, tHZCE is less than tLZCE and tHZWE is less than tLZWE for any given device.
9. thHigZhCEimapneddtaHnZcWeEsataretes. pecified with a load capacitance of 5 pF as in part (c) of “AC Test Loads and Waveforms [5]” on page 5. Transition is measured when the outputs enter a
10. This parameter is guaranteed by design and is not tested.
11. The internal write time of the memory is defined by the overlap of CE LOW and WE LOW. CE and WE must be LOW to initiate a write, and the transition of any of these
signals can terminate the write. The input data set-up and hold timing should be referenced to the leading edge of the signal that terminates the write.
