SN74HC153NG4

Overview

The SN74HC153NG4 is a dual 4-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It belongs to the 74HC logic family and operates on a single power supply ranging from 2V to 6V. The device features two independent multiplexers, each selecting one of four data inputs based on common select lines. It utilizes a 16-pin SOIC package with a width of 5.30mm. The component supports surface mount installation and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Dual independent 4-to-1 multiplexing capability
• Compatible with standard 5V CMOS logic levels
• Low input leakage current characteristics
• High noise immunity for reliable signal selection

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor interfaces
• Signal switching in test and measurement equipment
• Peripheral selection in embedded control circuits

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the package variant matches the required footprint, as 'N' denotes SOIC. Ensure the ordering part number aligns with the exact pin configuration and electrical specifications defined in the official datasheet before finalizing procurement.

Selection Notes

Select this component when dual independent multiplexing is required within a compact surface-mount form factor. The 74HC series offers compatibility with standard CMOS logic families. Consider the voltage range and temperature specifications to ensure suitability for the target application environment. Verify that the package dimensions fit the available PCB space constraints.

Part Context

This part is part of the broader 74HC153 family of dual 4-line to 1-line data selectors. It shares functional similarities with other variants differing primarily in packaging or environmental ratings. The SN74HC153NG4 specifically refers to the SOIC package version with green (RoHS compliant) manufacturing attributes. It serves as a fundamental building block for digital signal path management.

Replacement Considerations

Direct replacements include SN74HC153DR and SN74HC153D from Texas Instruments, which share identical logical functionality but may differ in package type (SOIC vs. SOIC). Cross-manufacturer equivalents such as the HC153 from other vendors should be verified for pinout compatibility and electrical parameter alignment.
