SN74ALS541-1NE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS541-1NE4 is an octal buffer and line driver with 3-state outputs manufactured by Texas Instruments. It belongs to the 74ALS logic family and features a 20-pin PDIP package. The device provides true data at its outputs and utilizes pnp inputs to reduce DC loading. A key characteristic of the -1 version is an increased recommended maximum low-level output current (IOL) of 48 mA, provided the supply voltage remains between 4.75 V and 5.25 V. It operates within a temperature range of 0°C to 70°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features a pinout arrangement where all inputs are located on one side of the package and all outputs are on the opposite side to facilitate printed circuit board layout.
• Includes dual output-enable controls implemented as a 2-input NOR gate; if either OE1 or OE2 input is high, all eight outputs enter a high-impedance state.
• Provides true data at the outputs, distinguishing it from the inverted SN74ALS540 variant.

• Driving bus lines
• Buffering memory address registers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix NE4 corresponds to the lead-free, RoHS-compliant version in tube packaging. Confirm the -1 designation is present to ensure the component supports the higher 48 mA low-level output current specification. Ensure the application environment stays within the specified 0°C to 70°C operating temperature range.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a non-inverting octal buffer with high drive capability is required for bus interfacing. The -1 suffix is critical for applications demanding up to 48 mA low-level output current. Consider the through-hole PDIP package for prototyping or environments requiring mechanical robustness over surface-mount alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the SN54ALS541/SN74ALS540/SN74ALS541 series of octal buffers and line drivers. The SN74ALS541 specifically offers true data transmission, whereas the SN74ALS540 provides inverted data. The -1 versions are identical to standard versions except for the enhanced low-level output current rating.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74ALS541-1N is the direct equivalent without the environmental suffix. SN74ALS541-1DW and SN74ALS541-1NSR offer the same electrical characteristics in SOIC and SOP packages respectively.
