DS1710
11 of 14
NOTES:
1.
All voltages are reference to ground
2.
Only one battery input is required.
3.
Measured with outputs open circuited.
4.
I
CC01
is the maximum average load which the DS1710 can supply to the memories.
5.
Z
CE
is an average input-to-output impedance as the input is swept from ground to V
CCI
and less than 4
mA is forced through Z
CE
.
6.
I
CC02
is the maximum average load current which the DS1710 can supply to the memories in the
battery backup mode.
7.
t
CE
max must be met to insure data integrity on power loss.
8.
Chip Enable Output
CEO
can only sustain leakage current in the battery mode.
9.
Applies only when loading partition switch.
10.
Measured with a load as shown in Figure 1.
11.
Measured with
DIS
at a logic high level.
12.
CEO
and
WEO
will be held high for a time equal to t
REC
after V
CCI
crosses V
CCTP2
.
13.
t
R
is the slew rate of V
CCI
from 4.25V to 4.75V or 2.50 to +2.70 volts.
14.
CEI
,
WEI
, A
W
- A
Z
run at minimum timing set and at voltage levels of 0V to 3V.
15.
All inputs within 0.3V of ground or V
CCI
and
CEI
within 0.3V of V
CCI
.
16.
The power-fail output signal (
PFO
) is driven active (V
OL
= 0.4V) when the V
CC
trip point occurs.
While active, the
PFO
pin can sink 4 mA and will maintain a maximum output voltage of 0.4 volts.
When inactive, the voltage output of
PFO
is 2.4 volts minimum and will source a current of 1 mA.
