The **TC7SL08F** is a high-speed CMOS 2-input AND gate manufactured by Toshiba. It belongs to the **TC7SL series**, which is designed for low-voltage operation while maintaining high-speed performance comparable to low-power Schottky TTL. --- ### 1. General Specifications The TC7SL08F is essentially a single logic gate housed in a small footprint package, making it ideal for space-constrained applications. | Feature | Specification | | :--- | :--- | | **Logic Type** | AND Gate | | **Number of Inputs** | 2 | | **Technology** | CMOS (Silicon Gate) | | **Operating Voltage ($V_{CC}$)** | 1.0V to 3.6V | | **Propagation Delay ($t_{pd}$)** | ~10ns (at 3V) | | **Output Current ($I_{OH}/I_{OL}$)** | ±1 mA (Min) | | **Package Type** | SSOP5 (SOT-353/SOT-23-5 variant) | --- ### 2. Logic Function The device performs the boolean function **$Y = A \cdot B$**. The output is HIGH only when both inputs are HIGH. **Truth Table:** | Input A | Input B | Output Y | | :---: | :---: | :---: | | L | L | L | | L | H | L | | H | L | L | | H | H | H | --- ### 3. Key Electronic Characteristics * **Low Power Consumption:** As a CMOS device, it draws extremely low quiescent current ($I_{CC} = 1 \mu\text{A}$ max at 25°C), making it suitable for battery-operated devices. * **High Speed:** Despite the low voltage, it offers high-speed switching performance. * **Input Protection:** The inputs are equipped with protection circuits against static discharge (ESD) and latch-up. * **Low Voltage Logic:** Specifically optimized for 1.8V, 2.5V, and 3.3V logic systems. --- ### 4. Pin Configuration (Typical SSOP5) | Pin No. | Symbol | Description | | :--- | :--- | :--- | | 1 | IN B | Logic Input B | | 2 | IN A | Logic Input A | | 3 | GND | Ground (0V) | | 4 | OUT Y | Logic Output Y | | 5 | $V_{CC}$ | Power Supply | --- ### 5. Common Applications * **Signal Gating:** Enabling or disabling a signal path based on a control line. * **Level Shifting:** Interfacing between different voltage domains (within the $V_{CC}$ range). * **Mobile Devices:** Used in smartphones and tablets due to the ultra-small SSOP5 package. * **Digital Logic Buffering:** Cleaning up logic signals before they reach a processor or peripheral.
