Table 4. Power Input Static Electrical Characteristics
Characteristics noted under conditions of 6.0 V  V_PWR  18 V, -40 C  T_C  125 C, and Calibrated Timers, unless otherwise
noted. Where applicable, typical values reflect the parameter’s approximate average value with V_PWR = 13 V, T_A = 25 C.
