Notes:
14.Test conditions for all parameters other than tri-state parameters assume signal transition time of 3 ns (1 V/ns) or less, timing reference levels of V
CC(typ)
/2, input
pulse levels of 0 to V
, and output loading of the specified I
OL
/I
OH
as shown in the “AC Test Loads and Waveforms” section.
15.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.
16.t
, t
, t
, and t
transitions are measured when the outputs enter a high impedence state.
17.The internal Write time of the memory is defined by the overlap of WE, CE
= V
, BHE and/or BLE = 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.
