Characteristics
The electrical characteristics involve the spread of values given within the specified supply voltage and junction
temperature range TJ from -25 °C to 125 °C. Typical values represent the median values related to TJ = 25°C. All voltages refer
to GND and the assumed supply voltage is VVCC = 14 V, if not otherwise mentioned.
The following characteristics are specified
