DM74ALS240AWMX

Overview

The DM74ALS240AWMX is an octal bus driver manufactured by Fairchild Semiconductor, belonging to the Advanced Low-power Schottky (ALS) logic family. It features eight non-inverting buffers with 3-STATE outputs housed in a 20-pin Small Outline Integrated Circuit (SOIC) package. The device operates within a standard TTL voltage range and provides bidirectional data transmission capabilities controlled by direction inputs.

Feature Summary

• Advanced low power Schottky technology for improved switching performance
• Octal configuration with three-state output capability
• Non-inverting buffer design for signal integrity

Applications

• Memory systems
• Microprocessor systems
• Asynchronous bidirectional data buses

Procurement Notes

Verify the specific suffix 'AWMX' against official Fairchild documentation to confirm package dimensions and lead finish specifications. Ensure compatibility with existing PCB footprints for SOIC-20 packages. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve over time.

Selection Notes

Select this component when designing systems requiring high-speed data transfer with low power consumption. The ALS series offers a balance between speed and power dissipation compared to standard TTL or LS families. Consider the 3-STATE feature for bus isolation requirements in complex digital architectures.

Part Context

This part is part of the DM74ALS240A family of octal bus drivers. It serves as a digital interface component in electronic circuits, facilitating data movement between different logic blocks. The ALS variant specifically targets applications needing faster switching than LS devices without the higher power draw of standard Schottky parts.

Replacement Considerations

Check for functional equivalents such as the DM74ALS240AN or other ALS-series octal drivers from Fairchild or onsemi. Verify pin compatibility and electrical characteristics before substitution.
