ELECTRICAL CHARACTERISTICS

STATIC ELECTRICAL CHARACTERISTICS

Table 4. Static Electrical Characteristics (continued)

Characteristics noted under conditions 3.1 V  VDD  5.5 V, 5.5 V  VPWR  18 V, -40 C  TC  125 C, unless otherwise

noted. Where applicable, typical values reflect the parameter’s approximate average value with VPWR = 13 V, TA = 25 C.
