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 1.
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.
