MC74ACT241DWR2

Overview

The MC74ACT241DWR2 is an octal buffer and line driver from the ACT logic series, manufactured by onsemi. It features non-inverting outputs with three-state capability, designed for memory address driving, clock distribution, and bus-oriented transmission or reception. The device operates within a supply voltage range of 4.5V to 5.5V. It provides high drive strength with outputs capable of sourcing and sinking 24mA. The component utilizes a 20-pin SOIC surface-mount package and ensures TTL-compatible input levels.

Feature Summary

• Octal buffer and line driver architecture for improved PC board density
• Three-state outputs suitable for driving bus lines or buffering memory address registers
• High drive capability with 24mA source and sink current capacity
• TTL-compatible inputs ensuring compatibility with standard logic families

Applications

• Memory address drivers
• Clock drivers
• Bus oriented transmitters or receivers

Procurement Notes

Verify the specific suffix DWR2 against the manufacturer's latest datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the procurement channel provides original manufacturer documentation to validate authenticity. Check for RoHS compliance status as indicated in official product change notices. Confirm availability of engineering samples if required for initial prototyping phases before full-scale production integration.

Selection Notes

Select this component when an octal buffer with three-state control is required for high-speed digital interfaces. The ACT series offers faster propagation delays compared to standard AC logic while maintaining CMOS power efficiency. Consider the 24mA output drive strength for applications requiring direct connection to heavy capacitive loads or long bus lines without additional buffering stages.

Part Context

This part belongs to the MC74ACT family of advanced CMOS logic devices. It serves as a functional equivalent to other industry-standard octal buffers like the SN74ACT241. The device is designed to replace older bipolar technologies in high-density digital systems, offering improved switching speeds and lower power consumption while maintaining pinout compatibility with legacy designs.

Replacement Considerations

Direct substitutes include MC74AC241 variants and compatible parts from other manufacturers such as SN74ACT241. Verify electrical characteristics and package tolerance matches before substitution.
