CD74HCT151M

Overview

The CD74HCT151M is an 8-input multiplexer manufactured by Harris Corporation, belonging to the 74HCT logic family. It operates on a single power supply ranging from 4.5V to 5.5V and features a 24-SOIC package. The device provides tri-state outputs with a maximum output current of 6mA for both high and low states. It supports a wide operating temperature range from -55°C to +125°C and has a moisture sensitivity level of MSL 3.

Feature Summary

• Provides eight selectable data inputs routed to a single output via three address lines.
• Features tri-state outputs allowing direct bus interfacing without external buffers.
• Compatible with standard TTL voltage levels due to HCT logic family characteristics.

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor-based designs
• Signal selection in test and measurement equipment

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm manufacturer origin, noting potential discrepancies between Harris Corporation branding and Texas Instruments production history. Check for updated datasheets reflecting any design changes or obsolescence notices prior to finalizing procurement specifications.

Selection Notes

Select this component when an 8-to-1 multiplexing function with tri-state capability is required in harsh thermal environments. Ensure the system voltage remains within the 4.5V to 5.5V range. Consider the 24-SOIC package dimensions for PCB layout constraints and verify compatibility with existing logic families for seamless integration.

Part Context

This part belongs to the 74HCT series of high-speed CMOS logic devices. While originally associated with Harris Semiconductor, these components are often linked to Texas Instruments' portfolio following industry acquisitions. The CD74HCT151M serves as a specialized variant within the broader 74HCT multiplexer lineup, offering specific packaging and electrical characteristics tailored for industrial applications.

Replacement Considerations

Consider CD74HCT151M96G4 from Texas Instruments as a verified alternative. Verify pinout compatibility and electrical specifications before substitution.
