SN74HC153N

Overview

The SN74HC153N is a dual 4-line to 1-line data selector/multiplexer from the Texas Instruments 74HC series. It integrates two independent multiplexers within a single 16-pin DIP package. The device operates on a single power supply ranging from 2V to 6V. It features true outputs and includes complete binary decoding for selecting one of four data sources per multiplexer using common address inputs.

Feature Summary

• Integrates two independent 4-to-1 multiplexers in a single package
• Operates with a single power supply voltage range
• Provides true output signals for direct logic interfacing
• Includes complete binary decoding for input selection

Applications

• Data routing in digital communication systems
• Address decoding in memory architectures
• Waveform generation circuits
• Parallel-to-serial data conversion

Procurement Notes

Verify the package type matches the required footprint, as the 'N' suffix typically denotes a plastic DIP package. Confirm the operating temperature range meets system requirements. Ensure the voltage supply aligns with the 2V to 6V specification. Check for RoHS compliance if environmental regulations apply. Validate pinout compatibility with existing PCB layouts.

Selection Notes

Select this component when dual independent multiplexing is required in a compact form factor. It is suitable for applications needing low power consumption and high noise immunity typical of HC logic. Consider the DIP package for prototyping or through-hole manufacturing needs. Ensure the supply voltage stays within the specified limits for reliable operation.

Part Context

This part belongs to the widely used 74HC logic family, known for high-speed CMOS technology. It serves as a standard solution for basic multiplexing tasks in general-purpose electronics. The dual configuration allows for efficient use of board space compared to using separate single multiplexers.

Replacement Considerations

Compatible substitutes include SN74HC153D (SOIC package) and SN74HC153PW (TSSOP package). Other manufacturers offer equivalent parts like MC74HC153. Verify pinout and electrical characteristics before substitution.
