DS2227
9 of 10
NOTES:
1.
WE
is high for a read cycle.
2.
OE
= V
IH
or V
IL
. If
OE
= V
IH
during write cycle, the output buffers remain in a high impedance
state.
3.
t
WP
is specified as the logical AND of
CE
and
WE
.
4.
t
DH
, t
DS
are measured from the earlier of
CE
or
WE
going high.
5.
t
DH
is measured from
WE
going high. If
CE
is used to terminate the write cycle then t
DH
= 20 ns.
6.
If the
CE
low transition occurs simultaneously with or later than the
WE
low transition, the
output buffers remain in a high impedance state in this period.
7.
If the
CE
high transition occurs prior to or simultaneously with the
WE
high transition, the output
buffers remain in a high impedance state in this period.
8.
If the
WE
is low or the
WE
low transition occurs prior to or simultaneously with the
CE
low
transition, the output buffers remain in a high impedance state in this period.
9.
Each DS2227 is marked with a 4-digit date code AABB. AA designates the year of manufacture.
BB designates the week of manufacture. The minimum expected t
DR
is defined as starting at the
date of manufacture.
10.
Timings are valid only when
CE
is tied low.
