Table 3. Static Electrical Characteristics
Characteristics noted under conditions 4.75 V ≤ VDD ≤ 5.25 V; 7.0 V ≤ VVFIRE_XX ≤ 35 V; VVDIAG_X = VVFIRE_XX; FEN 1 = FEN 2
= VDD; RR_LIMIT_X = 10 kΩ ±1%, RR_DIAG = 10 kΩ ±1%, -40°C ≤ TA ≤ +85°C, GND = 0 unless otherwise noted. Typical values
noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.
