DM74ALS540AWMX

Buffers, Drivers, Receivers, Transceivers Overview

The DM74ALS540AWMX is an octal inverting buffer and line driver featuring 3-STATE outputs, manufactured by onsemi. It utilizes a 20-Lead Small Outline Integrated Circuit (SOIC) package with JEDEC MS-013 dimensions. The device operates within a supply voltage range of 4.5V to 5.5V and supports a free-air operating temperature from 0°C to +70°C. Key electrical parameters include a maximum propagation delay of 12ns, high-level output current of -15mA, and low-level output current of 24mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

Features a data flow-thru pinout configuration where inputs and outputs are located on opposite sides of the package to enhance printed circuit board layout efficiency.
Incorporates a 2-input NOR gate for 3-STATE control, placing all eight outputs in a high impedance state if either control input is HIGH.
Utilizes advanced oxide-isolated, ion-implanted Schottky TTL process technology.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity and datasheet revision status prior to integration. Confirm that the specific SOIC package variant matches the required PCB footprint. Ensure environmental compliance requirements align with project specifications. Review absolute maximum ratings to prevent operational damage during system design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a high-density octal buffer with inverted logic is required. The specific pinout arrangement facilitates routing complexity reduction compared to standard parallel I/O layouts. Verify that the 3-STATE control mechanism meets the bus arbitration requirements of the target application architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ALS series of logic integrated circuits, representing Advanced Low-power Schottky technology. It serves as a direct functional equivalent to the DM74ALS240A series but provides a distinct physical pinout arrangement. The part is designed for general-purpose digital buffering and line driving applications within standard TTL voltage levels.
