STATIC ELECTRICAL CHARACTERISTICS
Table 4. Static Electrical Characteristics
Characteristics noted under conditions 3.1 V ≤ V_DD ≤ 5.25 V, 8.0 V ≤ V_PWR ≤ 16 V, -40°C ≤ T_C ≤ 125°C, unless otherwise
noted.(7) Where applicable, typical values reflect the parameter’s approximate average value with V_PWR = 13 V, T_A = 25°C.

Notes
7. T_C is the T_CASE of the package
8. Device operational. Table parameters may be out of specification.
9. Thermal shutdown of 16 mA pull-up and pulldown current sources only. 2.0 mA current source/sink and all other functions remain active.
10. This parameter is guaranteed by design but is not production tested.
