The 74153 is a dual 4-to-1 line data selector/multiplexer manufactured by National Semiconductor (now Texas Instruments). This integrated circuit selects one of four data sources from each of its two sections, based on the binary address applied to the select inputs. It's commonly used in digital logic circuits to route multiple data streams into a single channel.

Applications

• Data routing and multiplexing
• Address decoding
• Parallel-to-serial conversion
• Function generation
• Control logic circuits

Features

• Dual 4-to-1 line multiplexers
• Common select inputs for both multiplexers
• Separate strobe inputs for each multiplexer
• Low power consumption
• TTL compatible inputs and outputs

Benefits

• Efficient data selection and routing
• Reduced component count in complex circuits
• Simplified circuit design
• Improved system performance
• Enhanced flexibility in digital logic design

The 74153 operates based on the binary code applied to the select inputs. Each of the two multiplexers has its own strobe (enable) input, allowing for independent control. When the strobe input is high, the corresponding multiplexer is disabled, and its output is forced low. The common select inputs control which of the four data inputs is routed to the output. The device is available in various packages, including DIP and SOIC.

The 74153 is a versatile component for various digital logic applications where multiple data sources need to be selected and routed efficiently. Its dual multiplexer configuration allows for parallel data selection, which can significantly improve system throughput. The TTL compatibility ensures seamless integration with other TTL logic devices.
