SN74LS153DG4

Overview

The SN74LS153DG4 is a dual 4-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It integrates two independent multiplexers within a single 16-pin SOIC package, allowing for the selection of one of four data inputs per channel based on binary address signals. The device operates within a standard commercial temperature range of 0°C to 70°C and complies with RoHS standards.

Feature Summary

• Integrates two independent 4-to-1 multiplexing circuits in a compact package
• Utilizes standard TTL logic levels for input and output compatibility
• Includes enable inputs for controlling data flow to each multiplexer

Applications

• Data routing in digital logic systems
• Implementation of combinational logic functions
• Address decoding applications

Procurement Notes

Verify that the specific DG4 suffix corresponds to the tape-and-reel packaging variant rather than tube packaging when reviewing official ordering information. Confirm the component meets current environmental compliance requirements as specified in the manufacturer's documentation before finalizing procurement specifications.

Selection Notes

Select this component when a design requires two separate 4-input multiplexing channels using standard TTL logic families. Ensure the operating environment remains within the 0°C to 70°C commercial temperature range. Verify that the 16-pin SOIC footprint aligns with the target PCB layout constraints.

Part Context

This part belongs to the SN74LS series of logic integrated circuits, which are widely used in general-purpose digital electronics. The SN74LS153 provides a cost-effective solution for managing multiple data sources, serving as a fundamental building block for more complex arithmetic and control logic designs.

Replacement Considerations

Compatible substitutes include the SN74LS153N and SN74LS153DR. These alternatives offer identical logical functionality and pinout configurations, ensuring interchangeability in existing circuit designs without requiring schematic modifications.
