Table 3. Static Electrical Characteristics (continued)

Characteristics noted under conditions 9.0 V ≤ VPWR ≤ 18 V, -40°C ≤ TA ≤ 85°C unless otherwise noted. Typical values noted

reflect the approximate parameter means at TA = 25°C under normal conditions unless otherwise noted. Voltages are relative

to GND unless otherwise noted.
