CD74HC251M96

Overview

The CD74HC251M96 is a high-speed CMOS logic component manufactured by Texas Instruments, functioning as an 8-input multiplexer with three-state outputs. It operates within a supply voltage range of 2V to 6V and supports surface-mount installation in a 16-SOIC package. The device is designed for robust performance across an extended industrial temperature range of -55°C to +125°C. This specific variant belongs to the 74HC series and features a single independent circuit configuration.

Feature Summary

• Provides eight selectable data inputs routed to a single output line
• Outputs support three-state functionality for bus-driven applications
• Constructed using high-speed CMOS technology for low power consumption
• Compatible with standard TTL logic levels at 5V operation

Applications

• Data routing in digital communication systems
• Signal selection in microprocessor-based control circuits
• Address decoding for memory or peripheral selection
• Multiplexing analog or digital signals for processing

Procurement Notes

Verify the complete part number including suffixes such as E4 or G4 against official manufacturer documentation to ensure correct RoHS compliance and packaging specifications. Confirm that the 16-SOIC package dimensions match your PCB footprint requirements. Check current product status as legacy variants may be subject to discontinuation notices from Texas Instruments.

Selection Notes

Select this component when an 8-channel multiplexer with tri-state outputs is required within a 2V to 6V operating range. Ensure compatibility with the target logic family voltage levels. Consider the 16-SOIC package constraints for board space. Verify thermal management needs for operation up to 125°C if used in high-temperature environments.

Part Context

This component is part of the Texas Instruments CD74HCxx series, which offers high-speed CMOS performance compatible with standard 5V logic systems. The 'M96' suffix typically denotes a specific tape-and-reel packaging format intended for automated surface-mount assembly processes. It serves as a functional equivalent to other industry-standard 8-to-1 multiplexer designs.

Replacement Considerations

Publicly confirmed substitute part numbers include CD74HC251M96E4 and CD74HC251M. Verify pinout compatibility and electrical characteristics before substitution. Note that the original CD74HC251M may be obsolete; check for active status on replacement variants.
