CD74HCT138M96

Overview

The CD74HCT138M96 is a high-speed CMOS logic decoder/demultiplexer manufactured by Texas Instruments, originally designed by Harris Corporation. It features a single 3-to-8 line decoder circuit with inverted outputs. The device operates on a single power supply ranging from 4.5 V to 5.5 V and supports surface mount installation in a 16-SOIC package. It functions within an industrial temperature range of -55°C to +125°C.

Feature Summary

• Provides one 3-to-8 line decoding function with active-low outputs
• Compatible with standard TTL voltage levels due to HCT series design
• Supports wide operating temperature ranges for industrial applications

Applications

• Address decoding for memory systems
• Demultiplexing data streams
• Control signal distribution in digital circuits

Procurement Notes

Verify the manufacturer designation, as Texas Instruments currently produces this part based on original Harris designs. Confirm RoHS compliance status, as older Harris-produced units may not meet current environmental standards. Ensure the SOIC-16 package width matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when a single 3-to-8 decoder with inverted outputs is required. The HCT series ensures compatibility with TTL logic inputs while maintaining CMOS low power consumption. Verify that the 4.5V to 5.5V supply voltage aligns with your system's power rails.

Part Context

This component belongs to the CD74HCT138 family of logic ICs. It was originally developed by Harris Semiconductor before being acquired by Texas Instruments. The 'M96' suffix typically indicates specific packaging or tape-and-reel configurations used in mass production environments.

Replacement Considerations

CD74HCT138M96G4 is a verified lead-free replacement variant. Other compatible parts include SN74HCT138N for through-hole applications. Always verify pinout compatibility and electrical specifications before substituting.
