Table 4. 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 k ±1%, RR_DIAG = 10 k ±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.
