CD74HCT238M96

Overview

The CD74HCT238M96 is a high-speed CMOS logic device manufactured by Texas Instruments, functioning as a 3-to-8 line decoder or demultiplexer. It belongs to the HCT logic series and features a single circuit configuration with three inputs and eight outputs. The component 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. It utilizes a standard SOIC-16 package for surface mount installation.

Feature Summary

• Provides decoding and demultiplexing functions using high-speed CMOS technology compatible with TTL input levels.
• Includes two active-low enable inputs and one active-high enable input to facilitate system control and cascading expansion.

Applications

• Memory address decoding in computer systems
• Data routing and distribution networks
• Signal conversion and switching applications

Procurement Notes

Verify the specific suffix M96 against official Texas Instruments documentation to confirm packaging details such as reel specifications. Ensure compatibility with standard SOIC-16 footprint requirements during PCB layout. Confirm RoHS compliance status through current manufacturer datasheets before finalizing procurement orders.

Selection Notes

Select this component when a 3-to-8 decoding function is required with HCT-compatible input thresholds. It is suitable for designs needing wide industrial temperature operation and robust ESD protection characteristics inherent to the AC/HCT family. Verify that the 4.5V to 5.5V supply range aligns with the target system power rails.

Part Context

This part is part of the CD74HCT series, which bridges HC logic performance with standard TTL voltage compatibility. The M96 suffix typically denotes tape-and-reel packaging for automated assembly. It serves as a digital logic solution for managing multiple output lines from a compact binary input set.

Replacement Considerations

Check for direct equivalents like the CD74HC238M96 if lower voltage operation is needed, though input thresholds will differ. Verify pinout compatibility with other 3-to-8 decoders in the 74xx series before substitution.
