MC74ACT241DTR2

Overview

The MC74ACT241DTR2 is an octal buffer and line driver manufactured by onsemi, belonging to the 74ACT logic series. It features eight non-inverting outputs with three-state capability, designed for memory address driving, clock distribution, and bus-oriented transmission or reception applications. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical characteristics include TTL-compatible inputs and output drive capabilities sourcing and sinking 24 mA. It is housed in a TSSOP-20 surface-mount package and supports industrial operating temperatures from -40°C to +85°C.

Feature Summary

• Octal configuration provides eight independent non-inverting buffers for high-density circuit design
• Three-state outputs enable direct connection to bus lines without external switching components
• TTL-compatible input thresholds facilitate seamless integration with legacy digital systems
• High current drive capability supports direct loading of bus lines and memory registers

Applications

• Memory address drivers for data storage systems
• Clock signal distribution networks
• Bus-oriented transmitter and receiver circuits
• Parallel data buffering interfaces

Procurement Notes

Verify the complete part number including the DTR2 suffix to ensure correct tape-and-reel packaging and specific manufacturing lot codes. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the ordering quantity aligns with standard reel sizes to avoid partial reel handling issues during assembly.

Selection Notes

Select this component when an octal buffer with three-state control is required for 5V logic systems. The ACT series offers faster propagation delays compared to standard AC devices while maintaining CMOS power efficiency. Verify that the application requires TTL-compatible input levels and sufficient output current for the intended bus load before finalizing the design choice.

Part Context

This device is part of the broader 74ACT family of high-speed CMOS logic integrated circuits produced by onsemi. The family shares common pinouts and logical functions across various gate types, ensuring compatibility within mixed logic designs. The MC74ACT241 specifically addresses the need for multi-channel buffering in complex digital architectures requiring isolated output states.

Replacement Considerations

Compatible substitutes include the MC74ACT244, which offers similar functionality but with inverted outputs. Other equivalents may include variants from different manufacturers adhering to the standard 74ACT241 specification, provided they match the TSSOP-20 package and electrical parameters.
