74LVTH574D,118

Overview

The 74LVTH574D,118 is an octal D-type flip-flop manufactured by Nexperia. It features positive edge-triggering and three-state outputs. The device operates within a supply voltage range of 2.7V to 3.6V. It provides a maximum propagation delay of 3ns at 3.3V. The component supports high output currents of -32mA for low-level and 32mA for high-level states. It is housed in a 20-SOIC package with a width of 7.50mm. The operating temperature range spans from -40°C to +85°C.

Feature Summary

• Positive edge-triggered octal D-type flip-flop architecture
• Three-state non-inverting output capability
• High-speed operation with 3ns propagation delay
• Robust drive strength supporting 32mA output currents

Applications

• Parallel data storage and buffering
• I/O port expansion in embedded systems
• Register file implementation in digital logic circuits
• Data latch applications requiring fast switching speeds

Procurement Notes

Verify the manufacturer designation carefully, as NXP Semiconductors and Nexperia are related entities following corporate restructuring. Confirm that the specific suffix ',118' corresponds to the standard SOIC-20 tape and reel packaging configuration required for automated assembly processes. Ensure compatibility with 3.3V logic levels before integration into existing designs.

Selection Notes

Select this component when designing systems requiring fast octal latching with three-state isolation. It is suitable for applications demanding high-speed data transfer between microprocessors and peripheral devices. Consider the 3.3V operating voltage range and the specific package dimensions during PCB layout planning to ensure proper thermal and electrical performance.

Part Context

This part belongs to the 74LVTH series, which represents low-voltage TTL-compatible logic. The LVTH family is designed for high-speed applications while maintaining compatibility with traditional TTL input levels. It serves as a bridge between older 5V logic standards and modern low-voltage system architectures, offering improved speed over standard LVT variants.

Replacement Considerations

Public confirmed substitute part numbers include SN74LVTH574PWR from Texas Instruments.
