74LVT374WMX

Overview

The 74LVT374WMX is an octal D-type edge-triggered flip-flop manufactured by Fairchild Semiconductor, now part of onsemi. It features 3-STATE outputs designed for driving highly capacitive or low-impedance loads in bus-organized systems. The device operates within a supply voltage range of 2.7V to 3.6V. Key electrical parameters include a maximum clock frequency of 160 MHz and a maximum propagation delay of 4.9ns at 3.3V with a 50pF load. It contains one functional element with eight bits per element, housed in a 20-SOIC package.

Feature Summary

• Octal D-type edge-triggered flip-flop architecture
• 3-STATE outputs for direct bus connection without interface components
• High-impedance state capability for system isolation
• Optimized for driving highly-capacitive loads

Applications

• Buffer registers in digital systems
• I/O port implementations
• Bidirectional bus drivers
• Working registers in microprocessor-based designs

Procurement Notes

This component is officially classified as Obsolete and is no longer in production by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or surplus inventory. Sourcing should focus on verified suppliers offering genuine parts to ensure reliability, as new manufacturing units are not available. Procurement strategies must account for end-of-life status when planning long-term product lifecycles.

Selection Notes

Select this component for applications requiring octal data storage with high-speed performance up to 160 MHz. The 3.3V logic level compatibility makes it suitable for low-voltage digital interfaces. Designers should consider its obsolete status and plan for alternative sourcing or redesign if long-term supply continuity is critical. The 20-SOIC package offers surface-mount convenience for standard PCB layouts.

Part Context

The 74LVT374WMX belongs to the 74LVT series of low-voltage TTL-compatible logic devices. This series provides performance improvements over standard 5V logic while maintaining pinout compatibility. As an octal flip-flop, it serves as a fundamental building block for parallel data retention in digital circuits, bridging older 5V systems with emerging 3.3V architectures during the transition period of semiconductor technology.
