ELECTRICAL CHARACTERISTICS
STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics (continued)
Characteristics noted under conditions 5.5V ≤ V_SUP ≤ 18V, -40°C ≤ T_A ≤ 125°C for the 33912 and -40°C ≤ T_A ≤ 85°C for the
34912, unless otherwise noted. Typical values noted reflect the approximate parameter mean at T_A = 25°C under nominal
conditions, unless otherwise noted.
