SN74ALS541NSRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS541NSRE4 is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It belongs to the ALS logic series and is housed in a 20-pin Small Outline (SO) package. The device operates within a supply voltage range of 4.5V to 5.5V and supports a commercial operating temperature range of 0°C to 70°C. Key electrical characteristics include a high-level output current of -15mA and a low-level output current of 24mA. It features dual output enable controls with active-low polarity.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent non-inverting buffers or line drivers within a single integrated circuit.
• Three-state outputs allow multiple drivers to share a common data bus without signal contention.
• Dual output enable inputs provide flexible control over data transmission direction and bus isolation.

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Multiplexer output stages

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the SOIC-20 package dimensions match the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed octal buffering with low power consumption typical of the ALS series. It serves as a direct functional replacement for standard 74ALS541 devices in surface-mount applications. Consider the 24mA low-level sink capability for driving moderate capacitive loads on system buses.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is a surface-mount variant of the widely used 74ALS541 octal buffer family. It shares logical functionality with through-hole DIP versions but utilizes a compact SOIC package suitable for automated assembly. The device is part of Texas Instruments' extensive portfolio of legacy compatible logic components designed for industrial and commercial electronics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74ALS541NSR is the identical functional equivalent available in standard tape-and-reel packaging. SN74ALS541NE4 offers the same specifications in a 20-pin PDIP package for through-hole mounting. SN74HCT541NSRE4 provides similar functionality but requires CMOS-compatible input levels and different drive characteristics.
