Notes:
12. Test conditions for all parameters other than three-state parameters assume signal transition time of 3 ns (1V/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
as shown in the “AC Test Loads and Waveforms” section.
13. 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.
14. t
HZOE
, t
HZCE
, t
HZBE
, and t
HZWE
transitions are measured when the outputs enter a high-impedence state.
15. 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
