The **U74LVC2G86G-S08-R** is a high-performance, low-voltage CMOS device featuring two independent 2-input **Exclsuive-OR (XOR)** gates. It is widely used in high-speed computing and signal-processing applications due to its wide operating voltage range and high drive capability. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Logic Type** | XOR (Exclusive OR) | | **Number of Gates** | 2 | | **Number of Inputs** | 2 per gate | | **Supply Voltage ($V_{CC}$)** | 1.65V to 5.5V | | **Output Current ($I_{OH}/I_{OL}$)** | ±24mA (at 3.0V) | | **Propagation Delay ($t_{pd}$)** | ~3.6ns (at 3.3V) | | **Package Type** | SOP-8 (Surface Mount) | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Logic Function and Pinout The device operates based on the XOR logic gate principle: the output is **HIGH** only when the inputs are different. #### Truth Table (Single Gate) | Input A | Input B | Output Y | | :---: | :---: | :---: | | L | L | L | | L | H | H | | H | L | H | | H | H | L | #### Pin Configuration (SOP-8) 1. **1A**: Input 1 of Gate 1 2. **1B**: Input 2 of Gate 1 3. **2Y**: Output of Gate 2 4. **GND**: Ground 5. **2A**: Input 1 of Gate 2 6. **2B**: Input 2 of Gate 2 7. **1Y**: Output of Gate 1 8. **$V_{CC}$**: Power Supply --- ### 3. Distinctive Features * **$I_{off}$ Circuitry:** Supports partial power-down mode operation. This prevents damaging backflow current through the device when it is powered down. * **Overvoltage Tolerant Inputs:** Inputs can handle up to 5.5V even when $V_{CC}$ is lower (e.g., 3.3V), making it excellent for voltage level translation. * **Low Power Consumption:** Typical CMOS power efficiency, suitable for battery-powered handheld devices. --- ### 4. Common Applications * **Phase Detectors:** Comparing two clock signals. * **Parity Generators/Checkers:** Error detection in data transmission. * **Logic Level Shifting:** Bridging different voltage domains (e.g., 1.8V logic to 3.3V logic). * **Digital Comparators:** Determining if two binary bits are unequal.
