### 3. Core Features & Functional Details
#### Open-Drain Output
Unlike standard push-pull outputs, the **Open-Drain** architecture means the device can only pull the output signal to **Low (GND)**. To achieve a **High** state, an external pull-up resistor must be connected to the desired voltage rail.
#### I-off Circuitry
The device supports **partial power-down mode** operations. When the device is powered down ($V_{cc} = 0V$), the inputs and outputs are disabled, preventing damaging backflow current into the device.
#### Input Hysteresis
It typically features a small amount of hysteresis to ensure clean switching even with slightly noisy or slow-rising input signals.

### 4. Typical Application Circuit
Because it is open-drain, it is frequently used for **Voltage Level Translation**.
