Description
The 74138 is a 3-to-8 line decoder/demultiplexer IC that offers high-speed performance and is widely used in digital logic systems. It takes a 3-bit binary input and activates one of the eight outputs based on the input combination, while keeping the others inactive. Ideal for memory address decoding, data routing, and logic expansion.
With built-in enable inputs and active-low outputs, the 74138 is designed for use in microcontroller, microprocessor, and memory interfacing applications.
