DC CHARACTERISTICS (CONTINUED)<br />
Electrical Characteristics: Unless otherwise indicated: V DD = +<strong>1.8V</strong> to +5.5V, V SS = GND, T A = +25°C, V IN + = V DD /2, V IN - = V SS ,<br />
and R Pull-Up = 20 kΩ to V PU = V DD (see Figure 1-1).<br />
Parameters Symbol Min Typ Max Units Conditions<br />
Push-Pull <strong>Output</strong><br />
Pull-up Voltage V PULL_UP 1.6 — 5.5 V<br />
High Level <strong>Output</strong> Voltage V OH — — V PULL_UP V (see Figure 1-1) (Notes 3, 4)<br />
High Level <strong>Output</strong> Current leakage I OH_leak — — 1 µA Note 4<br />
<strong>Low</strong> Level <strong>Output</strong> Voltage V OL — — 0.6 V I OUT = 3mA/8mA @ V DD = <strong>1.8V</strong>/5.5V<br />
Short Circuit Current (Notes 3) I SC — ±30 — mA Not to exceed Absolute Max. Rating<br />
<strong>Output</strong> Pin Capacitance C OUT — 8 — pF<br />
Note 1: The input offset voltage is the center of the input-referred trip points. The input hysteresis is the difference between the<br />
input-referred trip points.<br />
2: V HYST at different temperatures is estimated using V HYST (T A ) = V HYST @ +25°C + (T A - 25°C) TC 1 + (T A - 25°C) 2 TC 2 .<br />
3: Limit the output current to Absolute Maximum Rating of 50 mA.<br />
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<br />
case, I OH_leak can be higher than 1 µA (see Figure 2-30).<br />
