[1] Typical ratings are not guaranteed. The values listed are at room temperature (+25 ˚C), nominal supply voltages.
[2] The RTC typically fails when VBAT drops below 1.6 V.
[3] Including voltage on outputs in 3-state mode.
[4] VDD supply voltages must be present.
[5] 3-state outputs go into 3-state mode when VDD is grounded.
[6] Accounts for 100 mV voltage drop in all supply lines.
