DM74ALS540AWM

Buffers, Drivers, Receivers, Transceivers Overview

The DM74ALS540AWM 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 inputs and outputs positioned on opposite sides to facilitate printed circuit board layout. 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 for LOW-to-HIGH transitions and up to 20ns for output enable times.

Buffers, Drivers, Receivers, Transceivers Feature Summary

Features a data flow-thru pinout configuration where all inputs are located on the side opposite to the outputs.
Incorporates a 2-input NOR gate control mechanism that places all eight outputs into a high impedance state if either G1 or G2 input is HIGH.
Utilizes an advanced oxide-isolated, ion-implanted Schottky TTL process to ensure switching performance across full temperature and supply ranges.

High-performance system bus driving
Clock buffering and distribution
Memory module addressing

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence. Confirm package specifications match the M20B designation for the 20-Lead SOIC variant. Ensure environmental compliance requirements align with project standards before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional data transfer is not required, as it functions strictly as an inverting buffer. Consider the specific pinout arrangement for PCB routing efficiency compared to standard layouts. Evaluate power consumption characteristics against system thermal constraints during continuous operation.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ALS logic family, known for improved speed over standard TTL while maintaining compatibility. It serves as a direct replacement for similar octal buffers in legacy designs requiring high-speed signal inversion and isolation.
