Table 4. Dynamic Electrical Characteristics
Characteristics noted under conditions of 3.0 V ≤ VDD ≤ 5.5 V, 6.0 V ≤ VPWR ≤ 32 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
= 13 V, TA = 25°C.
