SN74LS541DBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LS541DBR is an octal buffer and line driver manufactured by Texas Instruments. It belongs to the LS logic series and features eight non-inverting channels with three-state outputs. The device utilizes a surface-mount SOIC-20 package. It operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical characteristics include a maximum low-level output current of 24 mA and a maximum high-level output current of -15 mA. The propagation delay is specified at 18 ns when tested with a 5 V supply and 45 pF load.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the tape-and-reel packaging format on official distributor listings. Confirm the RoHS status, as indicated by the 'G4' suffix in related part numbers like SN74LS541DBRG4, if environmental compliance is required. Ensure the SOIC-20 footprint matches the target PCB design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state control is needed for TTL-compatible logic levels. The LS series offers standard speed and power consumption suitable for general-purpose digital applications. Consider the SOIC-20 package size for space-constrained surface-mount designs compared to through-hole alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the Texas Instruments SN74LS541 family of octal buffers and line drivers. It shares functional similarities with other variants such as the SN74LS541DW and SN74LS541NSRE4, differing primarily in packaging type and reel specifications. The device is designed for use in systems requiring multiple buffered outputs with tri-state capability.
