74AC138SCX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74AC138SCX is a single 3-to-8 decoder and demultiplexer belonging to the 74AC logic family. It operates within a supply voltage range of 2 V to 6 V and features surface-mount installation in a 16-SOIC package with a width of 3.90 mm. The device supports a wide operating temperature range from -40°C to +85°C. It provides high-current outputs capable of sourcing and sinking 24 mA, ensuring robust drive capability for digital logic applications.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides one-of-eight decoding or demultiplexing functionality using three address inputs and eight active-low outputs.
• Incorporates three enable inputs to control device operation, allowing for system expansion and hierarchical addressing.
• Delivers high output current drive capability suitable for direct interfacing with loads without additional buffering.

Signal Switches, Multiplexers, Decoders Applications

• Address decoding for memory and I/O port selection in embedded systems
• Demultiplexing data streams in communication interfaces
• Control signal distribution in industrial automation equipment

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'SCX' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and RoHS compliance status. Ensure the ordering quantity aligns with the standard factory pack size of 2500 units if bulk procurement is required. Cross-reference the part number alias 74AC138SCX_NL for potential inventory matching.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single 3-to-8 decoder is required within the 74AC logic family specifications. It is appropriate for designs needing 2 V to 6 V operation and surface-mount assembly. Consider the 74ACT138 variant if TTL-compatible input levels are necessary instead of CMOS levels.

Signal Switches, Multiplexers, Decoders Part Context

This component is part of the broader 74AC series of high-speed CMOS logic devices manufactured by onsemi. It shares functional similarities with other decoders like the 74AC139 but offers an 8-output configuration rather than 4. The SOIC-16 package is common across various logic families, facilitating standardized PCB footprint design.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The CD74AC138M96 from Texas Instruments serves as a functionally equivalent alternative with identical logic operations and pinout compatibility.
