Detailed Pin Configuration

The 74LVC1G139DCURE4 has a total of six pins: 1. GND (Ground) 2. A (Input A) 3. B (Input B) 4. Y (Output) 5. S (Select Input) 6. VCC (Supply Voltage)

Functional Features

• Acts as a multiplexer or demultiplexer depending on the select input (S) value.
• Can be used to select one of two inputs (A or B) and route it to the output (Y).
• Supports bi-directional data flow.

Advantages

• High-speed operation due to the use of CMOS technology.
• Wide supply voltage range allows compatibility with various systems.
• Small package size (SOT-23-6) enables space-saving designs.
• Low power consumption.

Disadvantages

• Limited to a single 2-input multiplexer/demultiplexer functionality.
• Not suitable for applications requiring more complex logic functions.

Working Principles

The 74LVC1G139DCURE4 utilizes CMOS technology to achieve high-speed operation. The select input (S) determines whether the IC acts as a multiplexer or demultiplexer. When S is low, input A is selected and routed to the output Y. Conversely, when S is high, input B is selected and connected to the output Y. The IC operates within a specified supply voltage range and provides bi-directional data flow.
