SN74ALS541-1NS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS541-1NS is an octal buffer and line driver with 3-state outputs manufactured by Texas Instruments. It belongs to the 74ALS logic series and provides true data at its outputs. The device features a pinout arrangement where inputs and outputs are located on opposite sides of the package, facilitating printed circuit board layout. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The -1 suffix indicates an increased recommended maximum low-level output current (IOL) of 48 mA when VCC is between 4.75 V and 5.25 V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'NS' corresponds to the SOP (Small Outline Package) variant in the manufacturer's latest documentation. Confirm RoHS compliance status and lead finish details such as NIPDAU. Ensure the application environment remains within the specified 0°C to 70°C operating temperature range. Cross-reference the datasheet revision date to confirm parameter validity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed buffering with reduced DC loading is required. The -1 version is suitable for applications demanding higher low-level output drive capability under specific voltage conditions. The through-hole compatible SOP package offers design flexibility compared to standard DIP options. Verify that the 3-state control requirements align with the dual output-enable inputs.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the SN54ALS541, SN74ALS540, and SN74ALS541 family of octal buffers and line drivers. It shares performance characteristics with the SN54ALS240A/SN74ALS240A series but utilizes a distinct pinout configuration. The family includes variants with inverted or true data outputs and different package styles such as PDIP, SOIC, and SSOP.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the 3-state control gate?

The 3-state control gate functions as a 2-input NOR gate. If either output-enable input (OE1 or OE2) is high, all eight outputs enter the high-impedance state.

How does the -1 version differ from the standard version?

The -1 versions of SN74ALS540 and SN74ALS541 are identical to the standard versions except that the recommended maximum IOL is increased to 48 mA, provided VCC is between 4.75 V and 5.25 V.
