SN74F240DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F240DWR is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74F logic series. It features two independent four-bit buffers with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5V to 5.5V and supports a low-level output current of 64mA and a high-level output current of -15mA. Designed for surface-mount installation, it functions reliably across an operating temperature range of 0°C to 70°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight buffered outputs with three-state capability for bus-oriented systems
• Features inverting logic polarity to reverse input signal states
• Utilizes bipolar F-series technology for high-speed performance

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and address decoding systems
• Clock drivers and buffer circuits
• High-current line driving applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 20-SOIC physical dimensions match the target PCB footprint. Ensure the component meets RoHS3 compliance standards if environmental regulations apply to the final product design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-drive capability for long traces or multiple loads. The bipolar F-series technology offers faster switching speeds compared to standard LS variants. Consider the thermal dissipation characteristics of the SOIC package under continuous load conditions during layout planning.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the broader SN74F family of high-speed bipolar logic devices. It serves as a functional equivalent to other octal buffers like the SN74LS240 but provides superior speed characteristics. The DWR suffix specifically denotes the reel-packaged version of the standard SN74F240DW.
