The **TC7SL08FU** is a high-speed CMOS 2-input AND gate manufactured by Toshiba. It belongs to the **7SL series**, which is designed for low-voltage operation while maintaining high speed and low power consumption. --- ### 1. General Specifications The TC7SL08FU is essentially a single logic gate housed in a very small package, making it ideal for space-constrained circuit designs. | Feature | Specification | | :--- | :--- | | **Logic Type** | AND Gate | | **Number of Inputs** | 2 | | **Technology** | CMOS (Low Voltage) | | **Package Type** | SSOP5 (also known as USV) | | **Operating Voltage ($V_{CC}$)** | 1.0V to 3.6V | | **Propagation Delay** | ~3.5 ns (at 3.3V) | | **Static Power Dissipation** | 10 $\mu$A (Maximum) | --- ### 2. Pin Configuration The device comes in a 5-pin package. The layout is standardized for single-gate logic devices: | Pin Number | Symbol | Description | | :--- | :--- | :--- | | 1 | IN B | Input B | | 2 | IN A | Input A | | 3 | GND | Ground (0V) | | 4 | OUT Y | Output Y ($A \cdot B$) | | 5 | $V_{CC}$ | Power Supply | --- ### 3. Logic Functionality 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 | --- ### 4. Key Electronic Characteristics * **Low Voltage Operation:** Unlike standard 74HC series (which usually start at 2V), the 7SL series can operate as low as **1.0V**, making it compatible with modern low-power microcontrollers. * **High Speed:** Despite the low voltage, it maintains switching speeds comparable to high-speed CMOS logic. * **Input Tolerance:** It features high-speed performance with low power dissipation, utilizing a silicon-gate CMOS structure. * **Output Drive:** Capable of driving standard CMOS loads; however, it is not intended for high-current driving (like LEDs) without a buffer. --- ### 5. Common Applications * **Signal Gating:** Used to enable or disable a clock signal or data line based on a control bit. * **Handheld Devices:** Due to the SSOP5 package and low voltage range, it is found in smartphones, tablets, and wearable tech. * **Logic Level Shifting:** Can be used in simple interface circuits between components operating at slightly different low-voltage rails.
