CD74HCT154M96G4

Overview

The CD74HCT154M96G4 is a high-speed CMOS logic device functioning as a 4-to-16 line decoder or demultiplexer. Manufactured by Texas Instruments, 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 SOIC surface-mount package with a width of 7.50 mm. It features active-low outputs and includes two enable inputs for chip selection control.

Feature Summary

• Provides decoding functionality for four binary select lines to activate one of sixteen distinct output channels simultaneously.
• Incorporates dual enable inputs that allow for cascading configurations or specific system-level power management requirements.
• Utilizes high-speed CMOS technology to ensure compatibility with standard TTL logic levels while maintaining low power consumption characteristics.

Applications

• Memory address decoding in digital systems
• Data routing and distribution networks
• Control signal generation for peripheral devices

Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance and lead-free status. Ensure the SOIC-24 package variant matches the target PCB footprint dimensions. Confirm the active-low output polarity aligns with the downstream circuit design requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-channel decoder with wide output capability is required in a compact surface-mount form factor. The HCT series ensures direct interface compatibility with TTL-driven systems. Consider the industrial temperature range if the application environment exceeds standard commercial limits.

Part Context

This device belongs to the Texas Instruments 74HCT logic family, designed for high-speed operation with CMOS efficiency. The M96 suffix indicates a specific tape-and-reel packaging configuration intended for automated surface-mount assembly processes, distinguishing it from tube-packaged variants.

FAQ

What is the logic function of the enable inputs?

The device features two active-low enable inputs. Both must be low for the selected output to go low; otherwise, all outputs remain high.

How are the outputs activated?

The outputs are active-low, meaning the selected channel drives a low logic level while unselected channels remain at a high logic level.
