CD74HC138M96

Signal Switches, Multiplexers, Decoders Overview

The CD74HC138M96 is a single 3-to-8 line decoder/demultiplexer manufactured by Texas Instruments. It utilizes high-speed silicon gate CMOS technology and operates within a supply voltage range of 2 V to 6 V. The device features three binary address inputs (A0, A1, A2) and eight active-low outputs that decode the address lines. It includes two active-low enable inputs (E1, E2) and one active-high enable input (E3) for cascading applications. The component is housed in a 16-pin SOIC package with tape-and-reel packaging.

Signal Switches, Multiplexers, Decoders Feature Summary

• High-speed silicon gate CMOS construction providing low power consumption comparable to standard CMOS while maintaining speed similar to Low-Power Schottky TTL logic.
• Three binary address inputs select one of eight active-low outputs when enabled, facilitating memory address decoding or data routing.
• Multiple enable inputs allow for easy cascading of multiple decoders to expand addressing capabilities without additional external gating.

Signal Switches, Multiplexers, Decoders Applications

• Memory address decoding in computer systems
• Data routing and distribution networks
• Cascaded decoding configurations for expanded I/O control

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'M96' confirms the tape-and-reel packaging format required for automated assembly processes. Ensure the order matches the HC logic family specifications rather than HCT variants, as input/output voltage thresholds differ significantly between these series. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single 3-to-8 decoder is required with low power dissipation and high switching speeds. The HC series is suitable for general-purpose CMOS applications operating between 2 V and 6 V. Consider the HCT variant if direct interfacing with 5 V TTL logic levels is necessary without level shifting circuitry.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the CD74HC138 family of decoders, which are widely used in digital logic circuits. The M96 suffix specifically denotes the reel-packaged version intended for surface-mount technology (SMT) production lines, distinguishing it from tube-packaged equivalents like the CD74HC138N.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Compatible substitutes include CD74HCT138M96 for TTL-compatible input levels, CD74HC238M96 for active-high outputs, and equivalent parts from other manufacturers such as SN74HC138N or MC74HC138AFR2G, provided pinouts and electrical characteristics align with the design requirements.
