Manufacturer:MOT Description: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. 7. tPOWER gives the minimum amount of time that the power supply should be at stable, typical Vcc values until the first memory access can be performed. 8. tHZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (d) of AC Test Loads. Transition is measured 500 mV from steady-state voltage. 9. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device. 10. 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 either 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. 11. The minimum Write cycle time for Write Cycle no. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD. |
