CD74HCT151MT

Overview

The CD74HCT151MT is a high-speed CMOS logic component manufactured by Texas Instruments, functioning as an 8-input multiplexer. It operates within a supply voltage range of 2V to 6V and supports surface-mount installation in a 16-SOIC package with a width of 3.90mm. The device features one independent circuit capable of selecting one of eight data inputs based on control signals. It is rated for operation across an extended temperature range from -55°C to +125°C. The output drive capability provides 5.2mA for both high and low states. Moisture sensitivity is classified as Level 1, indicating unlimited exposure to ambient conditions.

Feature Summary

• High-speed CMOS technology enables efficient signal routing in digital systems.
• Wide operating voltage range supports compatibility with various power supply standards.
• Extended temperature rating ensures reliable performance in harsh environments.

Applications

• Data acquisition systems requiring signal selection
• Digital communication interfaces for channel switching
• Industrial control circuits needing robust logic processing

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel quantity and packaging format. Ensure the procurement source explicitly lists the CD74HCT151MT part number to avoid confusion with similar variants like the CD74HC151MT or through-hole versions. Confirm RoHS compliance status matches project requirements before finalizing orders.

Selection Notes

Select this component when a single 8-to-1 multiplexer function is required in a surface-mount design. The HCT series compatibility allows integration with standard TTL logic levels while maintaining CMOS power efficiency. Consider the 16-SOIC package dimensions for PCB layout constraints and verify that the 2V to 6V supply range aligns with the system's power architecture.

Part Context

This part belongs to the Texas Instruments 74HC(H)T151 family of multiplexers. It shares functional similarities with other devices in the series but differs in package type and specific electrical characteristics. The MT suffix denotes the surface-mount SOIC variant, distinguishing it from PDIP or TSSOP options available within the same logical family.

Replacement Considerations

Public confirmed substitute part numbers include CD74HC151MT and CD74HCT151M. Verify pinout compatibility and electrical specifications before substitution. Note that some variants may have different supply voltage ranges or drive strengths.
