DS1312
10 of 11
NOTES:
1.
All voltages referenced to ground.
2.
Measured with outputs open circuited.
3.
I
CCO1
is the maximum average load which the DS1312 can supply to attached memories at V
CCO
>
V
CCI
-0.2V.
4.
I
CCO1
is the maximum average load which the DS1312 can supply to attached memories at V
CCO
>
V
CCI
-0.3V.
5.
All inputs within 0.3V of ground or V
CCI
.
6.
I
CCO2
is the maximum average load current which the DS1312 can supply to the memories in the
battery backup mode.
7.
Measured with a load as shown in Figure 2.
8.
Chip Enable Output
CEO
can only sustain leakage current in the battery backup mode.
9.
CEO
will be held high for a time equal to t
REC
after V
CCI
crosses V
CCTP
on power-up.
10.
BW
and
RST
are open-drain outputs and, as such, cannot source current. External pull-up resistors
should be connected to these pins for proper operation. Both
BW
and
RST
can sink 10 mA.
11.
t
CE
maximum must be met to ensure data integrity on power-down.
12.
In battery-backup mode, inputs must never be below ground or above V
CCO
.
13.
The DS1312 is recognized by Underwriters Laboratory (U.L.) under file E99151.
