Notes:

5. Test conditions assume signal transition time of 5 ns or less, timing reference levels of V_CC(typ.)/2, input pulse levels of 0 to V_CC(typ.), and output loading of the

specified I_OL/I_OHand 30 pF load capacitance.

6. At any given temperature and voltage condition, t_HZCEis less than t_LZCE, t_HZOEis less than t_LZOE, and t_HZWEis less than t_LZWEfor any given device.

7. t_HZOE, t_HZCE, and t_HZWEtransitions are measured when the outputs enter a high impedance state.

8. The internal write time of the memory is defined by the overlap of WE, CE₁= V_ILand CE₂= V_IH. All signals must be ACTIVE to initiate a write and any of these

signals can terminate a write by going INACTIVE. The data input set-up and hold timing should be referenced to the edge of the signal that terminates the write.
