DATA SHEET
3.4.1. Storage and Shelf Life
The permissible storage time (shelf life) of the sensors is unlimited, provided the sensors are stored at a maximum of
30 °C and a maximum of 85% relative humidity. At these conditions, no Dry Pack is required.
Solderability is guaranteed for one year from the date code on the package.
3.5. Recommended Operating Conditions
Functional operation of the device beyond those indicated in the “Recommended Operating Conditions/Characteris-
tics” is not implied and may result in unpredictable behavior of the device and may reduce reliability and lifetime.
All voltages listed are referenced to ground (GND).

3.6. Characteristics
at T_J = −40 °C to +170 °C, V_DD = 4.5 V to 5.5 V, GND = 0 V after programming and locking,
at Recommended Operation Conditions if not otherwise specified in the column “Conditions”.
Typical Characteristics for T_J = 25 °C and V_DD = 5 V.
