SN74LS151D

Overview

The SN74LS151D is an 8-input multiplexer manufactured by Texas Instruments in the SN74LS151 series. It features a single 8:1 configuration with complementary outputs and operates within a supply voltage range of 4.75V to 5.26V. The device supports CMOS/TTL output levels and functions across a temperature range of 0°C to 70°C. Packaged in a 16-pin SOIC format, it integrates one logic element per chip for data selection applications.

Feature Summary

• Provides complete binary decoding to select one of eight data sources
• Features complementary standard outputs (Y and Y-bar)
• Includes a strobe input that forces standard output low when high

Applications

• Data routing in digital systems
• Implementation of combinational logic functions
• Arithmetic circuit design such as full adders

Procurement Notes

Verify the specific suffix 'D' indicates the SOIC package variant rather than the PDIP version. Confirm the manufacturer designation aligns with Texas Instruments specifications for this part number. Ensure compatibility with required operating temperatures and voltage ranges before integration into final designs.

Selection Notes

Select this component when an 8-channel data selector with complementary outputs is required. It is suitable for general-purpose digital logic applications requiring TTL-compatible inputs and outputs. Consider the SOIC package constraints for board space and thermal management during selection.

Part Context

This component belongs to the SN74LS151 family of 8-input multiplexers. It serves as a fundamental building block for digital signal processing and control systems. The LS series ensures compatibility with standard transistor-transistor logic circuits while providing efficient data path management.

Replacement Considerations

Compatible substitutes include SN74LS151N and MC74LS151A. Verify pinout compatibility and electrical characteristics match the original requirements before substitution.
