SN74F541DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F541DWR is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V. The device provides high-level output currents up to -15 mA and low-level output currents up to 64 mA. Propagation delays are specified at 6 ns maximum for both high-to-low and low-to-high transitions under standard load conditions. It utilizes a 20-pin Small-Outline (DW) package and supports operation from 0°C to 70°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features data flow-through pinout with inputs on the opposite side of outputs to facilitate printed-circuit-board layout.
• Includes dual active-low output enable inputs that force all eight outputs into a high-impedance state when asserted.
• Designed specifically for driving bus lines or buffering memory address registers.

• Driving bus lines
• Buffering memory address registers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm status and packaging details. Confirm RoHS compliance and lead finish specifications match project requirements. Ensure the operating temperature range aligns with the intended application environment before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring octal buffering with tri-state control capabilities. Consider the F-series logic family characteristics regarding speed and drive strength relative to system timing constraints. Evaluate the SOIC-20 package dimensions against available board space and thermal management requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN54/74F series of octal buffers and drivers. It shares functional similarities with other devices in the 541 family but differs in manufacturing process and performance metrics compared to HC, HCT, or LVTH variants. The DWR suffix indicates a tape-and-reel packaging format suitable for automated assembly processes.
