Notes:
8. Test conditions assume signal transition time of 5 ns or less, timing reference levels of VCC(typ.)/2, input pulse levels of 0 to VCC(typ.), and output loading of the
specified IOL/IOH and 30 pF load capacitance.
9. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any
given device.
10. ItHZOE, tHZCE, tHZBE, and tHZWE 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 = VIL, BHE and/or BLE = VIL. 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.
