NOTES:
1. All voltages referenced to ground.
2. Measured with outputs open circuited.
3. I
CCO1
is the maximum average load which the DS1321 can supply to attached memories at V
CCO
> V
CCI
–0.2V.
4. I
CCO2
is the maximum average load which the DS1321 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
CCO3
is the maximum average load current which the DS1321 can supply to the memories in the battery backup
mode at V
CCO
> V
BAT
–0.2V.
7. Measured with a load as shown in Figure 1.
8. Chip Enable Outputs CEO1 – CEO4 can only sustain leakage current in the battery backup mode.
9. CEO1 through CEO4 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
.
