CD74HCT154MG4

Overview

The CD74HCT154MG4 is a high-speed CMOS logic device manufactured by Texas Instruments, functioning as a 4-to-16 line decoder/demultiplexer. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to +125°C. The component utilizes a 24-pin Small Outline Integrated Circuit (SOIC) package with a width of 7.50 mm. It features two enable inputs for control and provides active-low outputs. The device is RoHS compliant and lead-free.

Feature Summary

• High-speed CMOS technology ensures rapid switching performance suitable for demanding digital applications.
• Dual enable inputs provide flexible control over the decoding or demultiplexing operation.
• Active-low output configuration simplifies interfacing with various logic families.
• Extended industrial temperature range supports reliable operation in harsh environments.

Applications

• Address decoding in microprocessor-based systems
• Data distribution in digital communication circuits
• Memory selection in embedded systems

Procurement Notes

Verify the specific suffix MG4 indicates the tape-and-reel packaging variant distinct from the tube-packaged E version. Confirm RoHS compliance status and lead-free certification through official manufacturer documentation prior to procurement. Ensure the ordering part number matches the required package type and reel quantity specifications for your manufacturing process.

Selection Notes

Select this component when a 4-to-16 decoding function is required with high-speed CMOS performance. The HCT series compatibility allows direct interfacing with TTL-level inputs while maintaining CMOS noise immunity. Consider the SOIC package dimensions for PCB layout constraints and verify thermal requirements for the intended operating environment.

Part Context

This device belongs to the Texas Instruments CD74HCT family of high-speed CMOS logic components. The family offers robust performance with standard TTL-compatible input levels. The 154 series specifically addresses applications requiring one-of-many decoding or data routing functions across sixteen distinct lines.

Replacement Considerations

CD74HCT154M96 is a documented parameter-equivalent alternative from Texas Instruments. Verify pinout compatibility and electrical specifications before substitution. Other generic 74HCT154 equivalents may require validation of enable logic and output drive characteristics.
