DC CHARACTERISTICS (CONTINUED)
Electrical Specifications: Unless otherwise indicated, VDD = +1.6V to +5.5V, VSS = GND, TA = +25°C,VIN+ = VDD/2,
VINâ = VSS, and RL = 100 kΩ to VDD/2 (Refer to Figure 1-3).

Note 1: The input offset voltage is the center (average) of the input-referred trip points. The input hysteresis is the difference
between the input-referred trip points.
2: VHYST at different temperatures is estimated using VHYST (TA) = VHYST + (TA - 25°C) TC1 + (TA - 25°C)2 TC2.
3: Input bias current at temperature is not tested for SC-70-5 package.
4: Limit the output current to Absolute Maximum Rating of 30 mA.
AC CHARACTERISTICS
Electrical Specifications: Unless otherwise indicated, VDD = +1.6V to +5.5V, VSS = GND, TA = +25°C, VIN+ = VDD/2,
Step = 200 mV, Overdrive = 100 mV, and CL = 36 pF (Refer to Figure 1-2 and Figure 1-3).
