Electrical Characteristics: Diagnostic Functions
Note: Characteristics show the deviation of parameters at the given supply voltage and junction temperature.
Typical values show the typical parameters expected from manufacturing.
Vbb = 9 V to 16 V, Tj = -40 °C to +150 °C (unless otherwise specified)
typical values: Vbb = 13.5 V, Tj = 25 °C
