STATIC ELECTRICAL CHARACTERISTICS
STATIC ELECTRICAL CHARACTERISTICS (continued)
Characteristics noted under conditions of 7.0 V ≤ V_PWR ≤ 18 V, -40°C ≤ T_C ≤ 125°C, unless otherwise noted. Where
applicable, typical values reflect the parameter’s approximate average value with V_PWR = 14 V, T_A = 25°C.
