4. Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

6. Electrical Characteristics
T_amb = –40°C to +110°C, V_Batt = 9V to 16.5V, (basic function is guaranteed between 6.0V to 9.0V) reference point ground, unless
otherwise specified (see Figure 1-1 on page 2). All other values refer to pin GND (pin 2).
