74LVTH374WMX

Overview

The 74LVTH374WMX is a low voltage octal D-type flip-flop manufactured by Fairchild Semiconductor. It features positive-edge triggering and three-state outputs, designed for bus-oriented memory operations. The device operates within a supply voltage range of 2.5V to 3.6V. It is housed in a 20-pin SOIC W package with tape and reel packaging. This component has been discontinued and is no longer in production.

Feature Summary

• Octal D-type flip-flop architecture with separate inputs for each stage
• Positive-edge clock triggering mechanism for data capture
• Three-state output capability enabling efficient bus interfacing

Applications

• Bus-oriented memory register implementations
• I/O port buffering applications
• Clock driver circuits requiring high fan-out

Procurement Notes

This component is officially marked as obsolete and discontinued by the manufacturer. No new units are available from authorized distribution channels. Procurement efforts should focus on verifying the authenticity of existing surplus stock or identifying qualified replacement parts that meet equivalent electrical specifications and pin compatibility requirements.

Selection Notes

Designers must account for the discontinuation status when selecting this part. Verify if alternative logic families such as the 74LVT series offer current availability while maintaining similar voltage levels and performance characteristics. Ensure that any substitute component supports the required 2.5V to 3.6V operating range and maintains compatible input/output thresholds for system integration.

Part Context

The 74LVTH374 belongs to the Low Voltage TTL (LVTH) logic family, which bridges the gap between standard TTL and CMOS technologies. It provides fast switching speeds while operating at lower voltages than traditional 5V logic. The 'W' suffix indicates the wide-body SOIC package, and 'MX' denotes tape and reel packaging for automated assembly processes.

Replacement Considerations

The 74LVTH374 is obsolete. Potential substitutes include other octal D-type flip-flops from the 74LVTH or 74LVT families that maintain pin compatibility and voltage specifications. Verify functional equivalence before implementation.
