DM74ALS74AMX

Overview

The DM74ALS74AMX is a dual D-type positive-edge-triggered flip-flop manufactured by Fairchild Semiconductor. It contains two independent flip-flops, each with individual D, clock, clear, and preset inputs, alongside complementary Q and Q outputs. The device utilizes an advanced oxide-isolated, ion-implanted Schottky TTL process for improved AC performance and lower power consumption compared to standard S74 counterparts. It is functionally and pin-for-pin compatible with Schottky and LS TTL devices. The component is housed in a 14-pin SOIC package.

Feature Summary

• Dual independent positive-edge-triggered D-type flip-flops
• Individual control inputs for data, clock, clear, and preset
• Complementary Q and Q outputs per element
• Compatible with Schottky and LS TTL logic families

Applications

• Digital logic circuits requiring edge-triggered storage
• Data register implementations
• Shift register configurations
• State machine design

Procurement Notes

Verify the specific suffix 'MX' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing Schottky or LS TTL designs if replacing legacy components. Confirm RoHS compliance status as indicated in official documentation prior to integration.

Selection Notes

Select this component when dual independent D-type flip-flops are required with low power dissipation characteristics typical of the ALS series. It serves as a direct replacement for standard Schottky (S) and Low-power Schottky (LS) equivalents in systems demanding functional parity and pin compatibility without redesigning the board layout.

Part Context

This part belongs to the DM74ALS74 series, representing Advanced Low-power Schottky logic. Fairchild Semiconductor was acquired by onsemi, and these products continue under the onsemi brand while retaining original Fairchild part numbers. The series is designed for high-speed digital applications requiring reduced power consumption relative to earlier Schottky technologies.

Replacement Considerations

Functionally equivalent parts include DM74ALS74 and DM74AS74. Verify pinout compatibility before substitution. Cross-reference with LS TTL variants like DM74LS74 for backward compatibility in mixed-logic systems.
