Table 26. Switching Characteristics
Notes:
1.
Test conditions assume signal transition time of 1V/ns or higher, 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
and 30 pF load capacitance.

transitions are measured when the outputs enter a high-impedance state.
2.
3.
High-Z and Low-Z parameters are characterized and are not 100% tested.
4.
To achieve 55-ns performance, the read access should be CE# controlled. In this case t
ACE
is the critical parameter and t
SK
is
satisfied when the addresses are stable prior to chip enable going active. For the 70-ns cycle, the addresses must be stable
within 10 ns after the start of the read cycle.
5.
The internal write time of the memory is defined by the overlap of WE#, CE#1 = V
IL
, CE2 = V
IH
, B
HE
and/or B
LE
= 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 write.
