SN74ACT244DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT244DWR 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 4.5 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 9 ns at 5 V, high-level output current of -24 mA, and low-level output current of 24 mA. Static current is specified at 4 uA, with a maximum operating temperature of +85 C and minimum of -40 C. The component is housed in a 20-pin SOIC package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the SOIC-20 tape-and-reel packaging configuration required for surface-mount assembly processes. Confirm RoHS compliance status through the manufacturer's official documentation prior to integration. Ensure the ordering part number matches the exact logic family and pinout specifications defined in the latest datasheet revision to avoid compatibility issues during procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with independent control over two groups of four lines. The ACT series offers superior speed compared to standard HC or HCT families while maintaining CMOS power efficiency. Consider the 24 mA drive strength for moderate capacitive loads. Verify that the 4.5 V to 5.5 V operating range aligns with the system's power supply architecture and that the SOIC-20 footprint fits the PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the SNx4ACT244 family of octal buffers and drivers with 3-state outputs. It shares functional similarities with other members like the SN74ACT244DW but differs in packaging and reel specifications. The ACT series represents Texas Instruments' advanced CMOS technology, bridging the performance gap between older bipolar technologies and modern low-voltage CMOS solutions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74ACT244DW serves as a tube-packaged alternative within the same logical family. SN74HCT244DWR is a compatible option if HCT input thresholds are acceptable instead of ACT levels.
