AC Electrical Characteristics
Unless stated otherwise, VCC = MIN to MAX, Ambient Temperature -40 to +85° C, Note 13
WARNING: Under no circumstances are negative undershoots, of any amplitude, allowed when device is in
battery-backup mode.
Note 1: Limits at -40°C are guaranteed by design and are not production tested.
Note 2: SCL only.
Note 3: SDA and SQW/INT.
Note 4: ICCA—SCL at fSC max, VIL = 0.0V, VIH = VCC, trickle charger disabled.
Note 5: Specified with the I2C bus inactive, VIL = 0.0V, VIH = VCC, trickle charger disabled.
Note 6: VCC must be less than 3.63 V if the 250Ω resistor is selected.
