Working Principles

The 74LVC139D,112 is a decoder/demultiplexer IC that operates based on the binary address inputs provided to its A0, A1, and A2 pins. These inputs determine which output line will be activated. The G1 and G2 enable inputs control the overall functionality of the IC.

When the enable inputs are active, the IC decodes the binary address inputs and activates the corresponding output line. The selected output line goes high, while all other output lines remain low. This feature allows for easy selection of one output from multiple inputs.

The IC operates using low-voltage CMOS technology, which ensures high-speed operation and low power consumption. It can be powered by a wide range of supply voltages, making it compatible with various systems.
