STATIC ELECTRICAL CHARACTERISTICS
Table 3. 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. Typical values noted reflect the approximate parameter means V_PWR = 13 V, T_A = 25°C under nominal conditions unless
otherwise noted.

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