General Specifications | Parameter | Specification | | :--- | :--- | | **Logic Type** | AND Gate | | **Number of Inputs** | 2 | | **Package Type** | SSOP5 (SOT-353) | | **Operating Voltage (Vcc)** | 1.0V to 3.6V | | **Propagation Delay (tpd)** | 3.5 ns (Typical at 3.3V) | | **Output Current (Ioh/Iol)** | ±1 mA | | **Operating Temperature** | -40°C to 85°C | --- ### 2. Pin Configuration (SSOP5) The TC7SL08F comes in a small 5-pin package. The pinout is typically arranged as follows: | Pin Number | Symbol | Function | | :--- | :--- | :--- | | 1 | IN B | Data Input B | | 2 | IN A | Data Input A | | 3 | GND | Ground (0V) | | 4 | OUT Y | Data Output Y | | 5 | Vcc | Power Supply | --- ### 3. Logic Function The device performs the logical AND operation. The output (Y) is only **HIGH** if both inputs (A and B) are **HIGH**. **Truth Table:** | Input A | Input B | Output Y | | :---: | :---: | :---: | | L | L | L | | L | H | L | | H | L | L | | H | H | H | --- ### 4. Key Features * **Ultra-Small Footprint:** The SSOP5 package (also known as fV) is designed for high-density mounting. * **Low Voltage Operation:** Optimized for 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V logic systems. * **High Speed:** Performance is comparable to the 74LCX series while maintaining lower power consumption. * **Input Tolerance:** The inputs are designed to handle signals without needing complex level-shifting in many low-voltage scenarios. --- ### 5. Common Applications * **Mobile Devices:** Cell phones, tablets, and smartwatches. * **Signal Gating:** Enabling or disabling a signal path based on a control bit. * **Level Translation:** Used in mixed-voltage systems where small logic gates act as buffers or simple logic processors.
