This parameter is guaranteed by design, however it is not production tested.

Table 4. Power Input Static Electrical Characteristics

Characteristics noted under conditions of 6.0 V

 VPWR  18 V, -40 C  TC  125 C, and Calibrated Timers, unless otherwise

noted. Where applicable, typical values reflect the parameter’s approximate average value with VPWR = 14 V, TA = 25 C.
