SN74LS541DBRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LS541DBRG4 is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V. The device provides high-level output current of -8 mA and low-level output current of 24 mA. It functions in a temperature range from 0°C to +70°C and utilizes a 20-pin SOIC package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight non-inverting buffer channels with independent control
• Features three-state outputs for effective bus line driving applications
• Designed for standard TTL logic compatibility

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers
• Clock drivers
• Bus-oriented architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per manufacturer documentation. Confirm the SOIC-20 package dimensions match the target PCB footprint requirements. Ensure the operating temperature range of 0°C to +70°C aligns with the environmental conditions of the final assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between different logic families requiring octal buffering. Consider the 24 mA low-level sink capability for driving moderate loads. Verify that the 5V nominal supply voltage matches the system power rails. Evaluate the propagation delay characteristics against the maximum clock speed requirements of the digital circuit design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LS series of logic integrated circuits, representing a standard Low-power Schottky TTL family member. The SN74LS541 variant specifically offers octal configuration with tri-state functionality, distinguishing it from non-tri-state buffers like the SN74LS244 or inverting variants.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LS541DBR is a direct functional equivalent without the green compliance suffix. Other compatible parts include SN74LS541N and SN74LS541PW, provided the package type (PDIP or TSSOP) is acceptable for the application.
