MC74AC151DR2

Overview

The MC74AC151DR2 is an active 8-input multiplexer manufactured by onsemi. It belongs to the 74AC logic family and features eight data inputs, three address select lines, and complementary outputs. The device operates within a supply voltage range of 2V to 6V. It utilizes a 16-pin SOIC surface-mount package. The component supports industrial operating temperatures from -40°C to 85°C.

Feature Summary

• Provides high-speed data routing through eight selectable input channels
• Features complementary output configurations for versatile signal processing
• Operates across a wide supply voltage range suitable for various logic levels

Applications

• Data acquisition systems requiring channel selection
• Digital communication interfaces for signal routing
• Microprocessor peripheral expansion circuits

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with onsemi or authorized distributors before procurement. Confirm that the 16-pin SOIC package dimensions match the target PCB footprint requirements. Ensure the selected supplier provides valid traceability documentation for the active part number.

Selection Notes

Select this component when an 8-channel multiplexing function is required within the 74AC performance envelope. Consider the 2V to 6V supply range compatibility with the system power rails. Evaluate the propagation delay specifications against the maximum clock frequency requirements of the application circuit design.

Part Context

This part is a member of the 74AC series, which offers higher speed performance compared to standard 74LS logic families while maintaining CMOS low power consumption characteristics. The MC74AC151 variant specifically implements the 8-to-1 multiplexer architecture defined in the JEDEC standard for this logic type.

Replacement Considerations

Direct substitutes include other manufacturers' 74AC151 variants in compatible packages. Verify pinout compatibility and electrical parameter equivalence before substitution.
