SN74HC153DRE4

Overview

The SN74HC153DRE4 is a dual 4-line-to-1-line data selector/multiplexer manufactured by Texas Instruments. It belongs to the 74HC series of high-speed CMOS logic devices. The component integrates two independent multiplexers within a single package, allowing for efficient routing of digital signals. It operates on a single power supply with a voltage range of 2V to 6V. The device features low input current and supports surface-mount installation in an 8-pin SOIC package.

Feature Summary

• Integrates two independent 4-to-1 multiplexers for dual-channel signal selection
• High-speed CMOS technology ensures low power consumption and fast switching
• Compatible with standard 5V logic systems while supporting lower voltage operation

Applications

• Data routing in digital communication systems
• Address decoding in memory architectures
• Signal selection in microcontroller peripheral interfaces

Procurement Notes

Verify the exact suffix 'E4' against the manufacturer's official documentation to confirm lead-free status and specific tape-and-reel packaging details. Ensure the ordering part number matches the required package variant and temperature rating specified in the latest datasheet revision before finalizing procurement.

Selection Notes

Select this component when dual independent 4-to-1 multiplexing is required in a compact surface-mount form factor. It is suitable for designs needing CMOS compatibility with TTL-level inputs. Consider the 2V to 6V operating range to ensure compatibility with the system's power supply rails and logic voltage levels.

Part Context

This part is part of the widely used 74HC family of logic integrated circuits. The 74HC153 specifically provides dual multiplexer functionality, distinguishing it from single-channel variants. It serves as a fundamental building block for complex digital logic designs requiring signal path management.

Replacement Considerations

Check for direct pin-compatible alternatives such as the SN74HC153DR or other manufacturers' equivalents like the MC74HC153ADR. Verify that any substitute maintains the same 16-pin or 8-pin configuration depending on the specific package variant and electrical characteristics.
