The **U74LVC1G19G-AL6-R** is a high-performance CMOS logic integrated circuit. Specifically, it is a **1-of-2 Decoder/Demultiplexer** designed for low-voltage operation with high output drive capability. --- ### 1. General Specifications Below is a breakdown of the key technical parameters for this specific part: | Parameter | Specification | | :--- | :--- | | **Logic Type** | Decoder / Demultiplexer | | **Configuration** | 1-of-2 (1 Line to 2 Lines) | | **Supply Voltage (Vcc)** | 1.65V to 5.5V | | **Output Current** | ±24 mA (at 3.3V) | | **Operating Temperature** | -40°C to +85°C | | **Package Type** | SOT-363 (AL6) | | **Propagation Delay** | ~3.0 ns (at 3.3V) | --- ### 2. Functional Description The device functions as a demultiplexer where a single input signal is routed to one of two outputs based on a selection pin. It also includes an "Enable" pin to turn the outputs on or off. #### Logic Table | Inputs (Enable) | Inputs (Select) | Output Y0 | Output Y1 | | :---: | :---: | :---: | :---: | | L | L | **L** | H | | L | H | H | **L** | | H | X | H | H | *Note: **L** = Low Voltage, **H** = High Voltage, **X** = Don't Care.* --- ### 3. Key Features * **Wide Voltage Range:** Compatible with modern 1.8V, 2.5V, 3.3V, and 5V systems. * **Ioff Circuitry:** Supports partial power-down mode operation. This prevents damaging backflow current when the device is powered down. * **High Drive:** Capable of driving heavy capacitive loads or long PCB traces. * **Small Footprint:** The SOT-363 package is ideal for space-constrained mobile and consumer electronics. --- ### 4. Typical Applications 1. **Address Decoding:** Routing data to specific memory banks or peripherals. 2. **Signal Routing:** Switching a single data stream between two different paths. 3. **Digital Logic Compression:** Reducing the number of GPIO pins required on a microcontroller to control multiple devices. --- ### 5. Package Information (SOT-363) The "AL6" suffix refers to the 6-pin SOT-363 package. ```text Pin Configuration: 1. Select (A) 2. Enable (E) 3. Output (Y1) 4. GND 5. Output (Y0) 6. VCC ```
