Notes

10.

Upper and lower logic threshold voltage levels apply to SI, CS, and SCLK.

11.

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

Table 4. Static Electrical Characteristics (continued)

Characteristics noted under conditions of 3.0 V ≤ VDD ≤ 5.5 V, 8.0 V ≤ VPWR ≤ 28V, -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.
