ELECTRICAL CHARACTERISTICS

STATIC ELECTRICAL CHARACTERISTICS

Table 3. Static Electrical Characteristics

Characteristics noted under conditions VAC = VUSB = 5.0 V, -40°C ≤ TA ≤ 85°C, C1 = C2 = C4 = 1.0 μF and C3 = 0.1 μF (See

Figure 1), unless otherwise noted. Typical values noted reflect the approximate parameter means at VAC = VUSB = 5.0 V and

TA = 25°C under nominal conditions, unless otherwise noted.
