MC74ACT153DR2

Overview

The MC74ACT153DR2G is a high-speed dual 4-input multiplexer from the 74ACT series, manufactured by onsemi. It features common select inputs and individual enable inputs for each section, allowing selection of two lines of data from four sources. The device provides buffered outputs in true (non-inverted) form. It operates on a single power supply with a voltage range of 4.5V to 5.5V. Key electrical parameters include a maximum propagation delay of 11.5 ns and output drive currents of 24mA for both high and low states. It is housed in a 16-SOIC package and supports an operating temperature range of -40°C to 85°C.

Feature Summary

• Dual 4-input multiplexer architecture with common select lines
• Individual enable inputs for independent section control
• Buffered non-inverted outputs for signal integrity
• High-speed operation suitable for demanding digital applications

Applications

• Data routing in digital communication systems
• Function generation for logic circuits
• Address decoding in memory systems
• Signal switching in industrial control equipment

Procurement Notes

Verify the complete part number includes the 'G' suffix (MC74ACT153DR2G) as indicated in official documentation, which denotes RoHS compliance. Confirm the package type is 16-SOIC and check the moisture sensitivity level (MSL 1) for handling requirements. Ensure the supplier provides valid datasheets and material declarations to confirm compliance with current environmental standards before finalizing procurement.

Selection Notes

Select this component when a dual 4:1 multiplexer with ACT speed characteristics is required. It is suitable for designs needing 5V operation with moderate drive strength. Consider the 16-SOIC package constraints for PCB layout. Verify that the input voltage levels are compatible with the system logic family. This part is appropriate for applications requiring function generation capabilities alongside standard multiplexing.

Part Context

This component belongs to the 74ACT logic family, known for CMOS compatibility with TTL performance. The 74ACT153 variant specifically addresses needs for dual multiplexing in space-constrained designs. It serves as a functional equivalent to other industry-standard dual 4-input multiplexers within the same voltage and speed class, facilitating design upgrades or replacements in existing 5V logic systems.

Replacement Considerations

The MC74ACT153DG is a verified alternative from onsemi in tube packaging. Other manufacturers may offer pin-compatible equivalents, but verification of electrical parameters such as propagation delay and output current is essential to ensure functional interchangeability without circuit modification.
