STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics (continued)
Characteristics noted under conditions 8.0 V ≤ VPWR = VSUP ≤ 40 V, -40°C ≤ TA ≤ 135°C, unless otherwise noted. Typical
values noted reflect the approximate parameter means at TA = 25°C under nominal conditions, unless otherwise noted.

Notes
30. This parameter is guaranteed by design, not production tested.
31. Logic threshold voltages derived relative to a 3.3 V 10% system.
32. Pull-up circuits will not allow back biasing of VDD.
33. There are two elements in the RST circuit: 1) one generally lower threshold enables the internal regulator; 2) the second removes the
reset from the internal logic.
34. This parameter applies to the OFF state (tri-stated) condition of SO is guaranteed by design but is not production tested.
35. The Thermal Warning circuit does not force IC shutdown above this temperature. It is possible to set a bit in the MASK register to
generate an interrupt when overtemperature is detected, and the status bit will always indicate if any of the three individual Thermal
Warning circuits in the IC sense a fault.
