Notes
1. Typical values measured at Tamb = 25 °C.
2. When powering-up the device, VDD must exceed 1.5 V until stable operation of the oscillator is established.
3. Event counter mode: supply current dependant upon input frequency.
4. The I2C-bus logic is disabled if VDD < VEN
.
5. When the voltages are above or below the supply voltages VDD or VSS, an input current may flow; this current
must not exceed ±0.5 mA.
6. Tested on sample basis.
