The 74153 is a TTL logic IC that integrates two independent 4-to-1 data selectors in a single package.
It routes one of four data inputs to a single output for each channel based on shared select lines.
The device operates from a single 5 V supply and is compatible with standard TTL logic levels.
Each multiplexer includes an independent enable input for output control.
Typical applications include data routing, signal selection, bus multiplexing, and digital control systems.
