• Decodes three binary address inputs into eight mutually exclusive outputs
• Demultiplexes a single input into eight separate outputs based on the address inputs
• Low-voltage operation allows compatibility with various logic levels
• High-speed CMOS technology enables fast data processing

Advantages and Disadvantages

Advantages: - Low power consumption - Wide operating voltage range - High-speed operation - Compact package size

Disadvantages: - Limited number of address inputs - Not suitable for complex decoding applications

Working Principles

The NLV74LCX138DR2G operates by receiving three binary address inputs (A0, A1, and A2) and two enable inputs (E1 and E2). Based on the combination of these inputs, the IC decodes the address and activates the corresponding output line. When the enable inputs are low, all outputs are in a high-impedance state.

Detailed Application Field Plans

The NLV74LCX138DR2G is commonly used in various digital systems that require decoding and demultiplexing functions. Some application fields include: - Memory address decoding - Data routing and selection - Address decoding in microcontrollers - Programmable logic devices - Communication systems
