DS1314
10 of 12
NOTES:
2. All voltages referenced to ground.
3. Measured with outputs open circuited.
4. ICCO1 is the maximum average load which the DS1314 can supply to attached memories at VCCO ≥
VCCI -0.2V.
5. ICCO1 is the maximum average load which the DS1314 can supply to attached memories at VCCO ≥
VCCI -0.3V.
6. All inputs within 0.3V of ground or VCCI.
7. ICCO2 is the maximum average load current which the DS1314 can supply to the memories in the
battery-backup mode.
8. Measured with a load as shown in Figure 2.
9. Chip Enable Output ( CEO ) can only sustain leakage current in the battery-backup mode.
10. CEO will be held high for a time equal to tREC after VCCI crosses VCCTP on power-up.
11. 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.
12. tCE maximum must be met to ensure data integrity on power-down.
13. In battery-backup mode, inputs must never be below ground or above VCCO.
