STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics (continued)
Characteristics noted under conditions 4.75 V ≤ V_DD ≤ 5.25 V; 7.0 V ≤ V_{VFIRE_XX} ≤ 35 V; V_{VDIAG_X} = V_{VFIRE_XX}; FEN 1 = FEN 2
= V_DD; R_{R_LIMIT_X} = 10 kΩ ±1%, R_{R_DIAG} = 10 kΩ ±1%, -40°C ≤ T_A ≤ +85°C, GND = 0 unless otherwise noted. Typical values
noted reflect the approximate parameter means at T_A = 25°C under nominal conditions unless otherwise noted.
