CD74HCT153MT

Overview

The CD74HCT153MT is a dual 4-line to 1-line data selector/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 two independent multiplexers, each capable of selecting one of four data inputs based on address lines. It provides standard CMOS outputs with a high-level output current and low-level output current of 4mA each. The component is designed for surface-mount installation in a 16-SOIC package and supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Dual independent 4-to-1 multiplexer architecture
• Compatible with standard TTL logic levels via HCT series
• Wide industrial operating temperature range

Applications

• Data routing in digital systems
• Address decoding circuits
• Signal selection in measurement equipment

Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the 16-SOIC package and lead finish match the required design specifications. Check for RoHS compliance status as indicated in the latest datasheet. Ensure the component meets the required voltage and current ratings for the target application environment.

Selection Notes

Select this component when dual independent 4-to-1 multiplexing is required within a compact surface-mount footprint. The HCT series ensures compatibility with 5V TTL logic interfaces. Consider the wide temperature range if the application operates in harsh environments. Verify that the 4mA drive capability meets the load requirements of the downstream circuitry.

Part Context

This component is part of the broader 74HC(T)153 family of multiplexers produced by Texas Instruments. It shares functional similarities with other devices in the 74HCT series but is distinguished by its specific dual 4-to-1 configuration and SOIC packaging. It serves as a fundamental building block for complex digital logic designs requiring signal path management.

Replacement Considerations

Publicly confirmed substitute part numbers include CD74HCT153M96 and CD74HCT153MT. These alternatives offer parameter-equivalent performance and may be considered for sourcing purposes if the primary part is unavailable.
