CD74HC154MG4

Overview

The CD74HC154MG4 is a high-speed CMOS logic component manufactured by Texas Instruments, functioning as a 4-to-16-line decoder or demultiplexer. It operates within a supply voltage range of 2 V to 6 V and features a 24-pin SOIC package. The device supports surface-mount installation and maintains an operating temperature range from -55 °C to +125 °C. Key electrical characteristics include a propagation delay of 44 ns and output drive capabilities of 5.2 mA for both high and low states. It is designed to interface with standard LSTTL loads.

Feature Summary

• Provides decoding and demultiplexing functions through four address inputs and sixteen active-low outputs.
• Features two enable inputs that facilitate cascading configurations and demultiplexer data input operations.
• Delivers balanced propagation delays and transition times while maintaining significantly lower power consumption compared to LSTTL logic ICs.

Applications

• Signal processing systems requiring address decoding
• Automation and process control equipment
• Memory addressing applications

Procurement Notes

Verify the specific suffix 'G4' against current manufacturer documentation to confirm compliance with RoHS directives and material composition changes. Ensure the ordering information matches the exact package style and tape-and-reel specifications required for your assembly line. Cross-reference the datasheet revision date to validate all electrical parameters before finalizing procurement decisions.

Selection Notes

Select this component when a wide supply voltage range and industrial temperature stability are required for decoding tasks. The HC series offers compatibility with standard logic families while providing lower power dissipation than older technologies. Consider the 24-pin SOIC footprint for PCB layout constraints and verify that the 5.2 mA output current meets the fan-out requirements of the connected load circuits.

Part Context

This part belongs to the Texas Instruments CD74HC154 family of high-speed CMOS logic devices. It serves as a successor to earlier variants like the CD74HC154ME4, incorporating updated manufacturing processes and packaging standards. The component is categorized under encoders, decoders, multiplexers, and demultiplexers within the broader logic integrated circuit portfolio.

Replacement Considerations

The CD74HC154M96 is listed as a manufacturer-recommended alternative to discontinued variants in the same family. Verify pinout compatibility and electrical specifications before substituting.
