SN74ALS540DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS540DW is an octal buffer and line driver manufactured by Texas Instruments, belonging to the ALS logic series. It features eight inverting inputs driving three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 12 ns, high-level output current of -15 mA, and low-level output current of 24 mA. It functions reliably across a temperature range of 0°C to +70°C with a maximum operating supply current of 22 mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides octal buffering with inverting logic functionality for signal conditioning.
• Integrates three-state outputs to facilitate bus-oriented communication systems.
• Utilizes Advanced Low-power Schottky (ALS) technology for optimized speed and power consumption.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized channels due to End-of-Life status. Confirm RoHS compliance details as specified in official documentation. Ensure packaging integrity matches required surface-mount specifications. Validate lot traceability against manufacturing records prior to integration into production lines.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when inverting octal buffering with three-state capability is required. Consider the 12 ns propagation delay for timing constraints. Verify that the 20-SOIC package fits the PCB layout. Ensure the 4.5 V to 5.5 V supply range aligns with system power rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ALS540 family of octal buffers. It is distinct from non-inverting variants like the SN74ALS541. The DW suffix indicates a plastic small-outline package. It serves as a digital logic interface component within broader integrated circuit ecosystems.
