Notes:
10. Test conditions for all parameters other than tri-state parameters assume signal transition time of 3 ns (1V/ns) or less, timing reference levels of V
pulse levels of 0 to V
, and output loading of the specified I
CC(typ.)
11. At any given temperature and voltage condition, t
given device.
12. t
, t
, t
, and t
transitions are measured when the outputs enter a high impedence state.

13. The internal Write time of the memory is defined by the overlap of WE, CE = V
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.
