Notes:
10.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
/I
and 30-pF load capacitance.
11. 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.
12.t
, t
, t
, and t
transitions are measured when the outputs enter a high-impedance state.
13.When both byte enables are toggled together this value is 10 ns.
14.The internal Write time of the memory is defined by the overlap of WE, CE
= V
, BHE and/or BLE = V
, CE
= V
. 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.
