DS1385/DS1387
012496 17/20
NOTES:
1. All voltages are referenced to ground.
2. All outputs are open.
3. Applies to the AD0–AD7 pins and the SQW pin when each is in the high impedance state.
4. The IRQ pin is open drain.
5. Measured with a load as shown in Figure 4.
6. All other inputs at CMOS levels.
7. Measured with a load as shown in Figure 4.
8. The real–time clock will keep time to an accuracy of
±
1 minute per month during data retention time for the
period of t
DR
.
9. Applies to DS1385 and DS1385S only.
