Working Principles

The NLV74HC138ADTR2G is based on the principle of combinational logic. It uses a combination of address inputs (A0, A1, and A2) to select one of the eight outputs (Y0 to Y7). The enable inputs (E1 and E2) control the functioning of the decoder/demultiplexer. When enabled, the selected output becomes active, while all other outputs remain inactive.

Detailed Application Field Plans

  • Address decoding in microcontrollers and microprocessors
  • Data routing in multiplexing applications
  • Memory addressing in digital systems
  • Signal selection in communication systems
  • Control signal generation in industrial automation
