3.6. Characteristics
at TJ = −40 °C to +170 °C, VDD = 4.5 V to 14 V, after programming and locking of the device,
at Recommended Operation Conditions if not otherwise specified in the column “Conditions”.
Typical Characteristics for TJ = 25 °C and VDD = 5 V.
For all other temperature ranges this table is also valid, but only in the junction temperature range defined by the
temperature range (Example: For K-Type this table is limited to TJ = −40 °C to +140 °C).
All voltages listed are referenced to ground (GND).
