Description

Product Description

The 74153 is a high-performance Dual 4-to-1 Data Selector/Multiplexer IC widely used in digital logic design and signal routing applications. It contains two independent 4-to-1 multiplexers within a single 16-pin package, allowing for the efficient selection of data from multiple input lines.

Each multiplexer has four data inputs, one enable input, and two common select lines, allowing you to control which input is routed to the output. The 74153 is ideal for projects requiring digital signal switching, data routing, function generation, or implementing logic functions with minimal external components.

The IC supports high-speed TTL logic, delivering reliable performance and compatibility with microcontrollers, digital systems, and logic circuits found in embedded systems, robotics, industrial controls, and educational projects.
