DS1312
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 DS1312 can supply to attached memories at VCCO >
VCCI -0.2V.
5. ICCO1 is the maximum average load which the DS1312 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 DS1312 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.
14. The DS1312 is recognized by Underwriters Laboratories (UL) under file E99151.
