SN74ACT244DWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT244DWRE4 is an octal buffer and line driver manufactured by Texas Instruments, belonging to the advanced CMOS (ACT) logic family. It features eight non-inverting channels organized into two groups of four, each controlled by a separate output enable (OE) input. The device operates within a supply voltage range of 4.5V to 5.5V and provides three-state outputs with high drive capability of ±24mA. It exhibits a maximum propagation delay of 9ns at 5V and accepts TTL-compatible inputs while maintaining CMOS output levels. Designed for surface-mount applications, it utilizes a 20-pin SOIC package in tape-and-reel format.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal buffering architecture with independent control over two four-bit channel groups via dedicated output enable pins
• Three-state output configuration enabling direct bus connection and shared signal line management
• TTL-compatible input thresholds allowing seamless interfacing with standard digital logic systems
• High current drive capability supporting robust signal transmission across loaded bus environments

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers for high-density storage systems
• Clock distribution networks requiring precise timing signals
• Bus-oriented receivers and transmitters in industrial control systems
• Signal processing interfaces demanding fast switching speeds

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'RE4' confirms the tape-and-reel packaging variant distinct from tube-packaged equivalents like the DW or PWG4 versions. Confirm RoHS compliance status through official manufacturer documentation as environmental certifications may vary by production batch. Ensure the ordering part number matches the required package type and reel quantity specifications for automated assembly processes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring high-speed data buffering with independent channel enablement. The ACT series offers superior speed compared to standard HC logic while maintaining low power consumption. Consider the ±24mA drive strength for driving multiple loads or long traces. Verify that the 4.5V minimum supply voltage aligns with the system's power rail availability.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the broader SN74ACT244 family, which includes variants with different packaging options such as TSSOP (PW/PWR) and standard SOIC (DW). The RE4 suffix specifically denotes the tape-and-reel packaging suitable for high-volume surface-mount technology (SMT) manufacturing lines. All variants share identical electrical characteristics and pinouts, differing only in physical packaging and shipping units.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74ACT244DW: Identical electrical performance in tube packaging. SN74ACT244PWR: Same functionality in TSSOP-20 tape-and-reel format. SN74ACT244PWG4: Green TSSOP variant with equivalent specs.
