DC CHARACTERISTICS (CONTINUED)
Electrical Characteristics: Unless otherwise indicated: V_DD = +1.8V to +5.5V, V_SS = GND, T_A = +25°C, V_IN+ = V_DD/2, V_IN- = V_SS,
and R_Pull-Up = 20 k to V_PU = V_DD (see Figure 1-1).

Note 1: The input offset voltage is the center of the input-referred trip points. The input hysteresis is the difference between the
input-referred trip points.
2: V_HYST at different temperatures is estimated using V_HYST (T_A) = V_{HYST @ +25°C} + (T_A - 25°C) TC₁ + (T_A - 25°C)² TC₂.
3: Limit the output current to Absolute Maximum Rating of 50 mA.
4: The pull-up voltage for the open drain output V_{PULL_UP} can be as high as the absolute maximum rating of 10.5V. In this
case, I_{OH_leak} can be higher than 1 µA (see Figure 2-30).
