Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Logic Function** | 2-Input NOR Gate | | **Technology** | Silicon Gate CMOS | | **Operating Voltage ($V_{CC}$)** | 1.0V to 3.6V | | **Output Current ($I_{OH}/I_{OL}$)** | ±1 mA (at $V_{CC}$ = 3.0V) | | **Propagation Delay ($t_{pd}$)** | 20ns (typical at 3.0V) | | **Package Type** | SSOP5 (SOT-353/SMV) | | **Operating Temperature** | -40°C to 85°C | --- ### 2. Pin Configuration (SSOP5) The device is housed in a small 5-pin package, making it ideal for compact electronic designs. | Pin Number | Symbol | Function | | :---: | :--- | :--- | | 1 | IN B | Input B | | 2 | IN A | Input A | | 3 | GND | Ground (0V) | | 4 | OUT Y | Output Y | | 5 | $V_{CC}$ | Power Supply | --- ### 3. Logic Functionality The NOR gate follows the logic equation: $Y = \overline{A + B}$. The output is **HIGH** only when both inputs are **LOW**. **Truth Table:** | Input A | Input B | Output Y | | :---: | :---: | :---: | | L | L | H | | L | H | L | | H | L | L | | H | H | L | --- ### 4. Distinctive Features * **Low Voltage Operation:** Optimized for battery-powered devices (1.0V to 3.6V range). * **High Input Impedance:** Minimal current draw from the signal source. * **Ultra-Small Footprint:** The SSOP5 (SMV) package saves significant PCB space compared to traditional DIP or SOIC packages. * **Power-Down Protection:** Inputs are tolerant to voltages up to 3.6V even when $V_{CC}$ is 0V, preventing current backflow. --- ### 5. Common Applications * **Mobile Devices:** Smartphones, tablets, and wearables where space and power consumption are critical. * **Signal Gating:** Enabling or disabling digital signals based on specific conditions. * **Logic Inversion:** Can be used as a simple inverter if one input is tied to Ground. * **Level Shifting:** Interfacing between different low-voltage logic domains.
