NOTES:
1.
In order to initialize the circuit, CE
1
should be kept at V
IH
or CE
2
should be kept at V
IL
for 100
μ
s after power-up, followed by at
least 8 dummy cycles.
2.
AC characteristics are measured at t
T
= 5 ns.
3.
AC characteristics are measured at the following condition (see
figure at right).
4.
Address is latched at the negative edge of CE
1
or at the positive
edge of CE
2
.
5.
Measured with a load equivalent to 2TTL + 100 pF.
6.
Data is latched at the positive edge of W/R or at the positive
edge of CE
1
or at the negative edge of CE
