MC74ACT153M

Overview

The MC74ACT153M is a dual 4-input multiplexer belonging to the 74ACT logic family, manufactured by onsemi. It features two independent multiplexing circuits within a single package, each selecting one of four data inputs based on two address bits. The device operates with a supply voltage range of 4.5 V to 5.5 V and exhibits a propagation delay of 9.5 ns at 5 V. It is housed in a 16-pin PDSO (SOIC) surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual independent 4-to-1 multiplexing functionality
• High-speed CMOS technology for low power consumption
• Compatible with standard TTL logic levels
• Surface-mount packaging for automated assembly

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor interfaces
• Signal selection in test and measurement equipment
• Peripheral interface management in embedded controllers

Procurement Notes

Verify the specific suffix 'M' against current manufacturer documentation, as some sources indicate this variant may be discontinued or superseded. Confirm RoHS compliance status and material composition declarations directly with onsemi or authorized distributors before procurement. Ensure the package type matches the intended PCB footprint design requirements.

Selection Notes

Select this component when dual 4-input multiplexing is required within a compact surface-mount form factor. The ACT series offers faster switching speeds compared to standard HC variants while maintaining CMOS power efficiency. Verify that the 4.5 V to 5.5 V supply voltage range aligns with the system's power architecture and that the SOIC-16 package fits the available board space constraints.

Part Context

This part belongs to the widely adopted 74ACT logic family, known for performance comparable to ALS TTL but with CMOS power characteristics. The 153 designation specifically refers to the dual 4-input multiplexer configuration. This family is commonly used in general-purpose digital logic applications requiring reliable signal switching and moderate speed operation in industrial and consumer electronics.

Replacement Considerations

Check for active equivalents such as MC74ACT153DR2G or compatible parts from other manufacturers like TI (SN74ACT153). Verify pinout compatibility and electrical specifications before substitution. Note that some variants may have different packaging or lead times.
