Notes:
8. 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_OH and 30 pF load capacitance.
9. At any given temperature and voltage condition, t_HZCE is less than t_LZCE, t_HZBE is less than t_LZBE, t_HZOE is less than t_LZOE, and t_HZWE is less than t_LZWE for any
given device.
10. It_HZOE, t_HZCE, t_HZBE, and t_HZWE transitions are measured when the outputs enter a high-impedance state.
11. The internal write time of the memory is defined by the overlap of WE, CE = V_IL, BHE and/or BLE = V_IL. 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.
