CD74HCT151M

Overview

The CD74HCT151M is a single 8-line-to-1-line data selector or multiplexer manufactured by Texas Instruments. It belongs to the 74HCT logic series and operates on a single power supply ranging from 4.5V to 5.5V. The device features eight digital inputs, three address select lines, an enable input, and complementary outputs. It is housed in a 16-SOIC package with a narrow body width of 3.90mm. The component supports surface mount installation and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high-speed CMOS performance compatible with TTL logic levels
• Features complementary outputs for direct interfacing with downstream logic circuits
• Includes an active-low enable input to control data transmission states

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor-based designs
• Waveform generation using counter-driven selection

Procurement Notes

Verify the exact part number against manufacturer documentation to confirm the HCT logic family and SOIC-16 package configuration. Ensure compatibility with the 4.5V to 5.5V operating voltage range required by the specific circuit design. Check for RoHS compliance status and moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when a single 8-channel multiplexer with TTL-compatible inputs is required. The HCT series ensures compatibility with standard 5V logic families while offering CMOS low power consumption. Consider the wide industrial temperature range if the application involves harsh environmental conditions.

Part Context

This device is part of the broader 74HC(T)151 family of multiplexers produced by Texas Instruments. It shares functional similarities with other members like the SN74HC151 but differs in input threshold characteristics due to the HCT technology. The CD prefix indicates it is a commercial grade variant designed for general-purpose electronic applications.

Replacement Considerations

Check for obsolete status as some distributors list this specific suffix as end-of-life. Potential substitutes include the SN74HC151DR for HC series compatibility or the CD74HC151M for equivalent functionality within the same package.
