STATIC ELECTRICAL CHARACTERISTICS
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.
