74LVT574MTCX

Overview

The onsemi 74LVT574MTCX is an octal D-type flip-flop with three-state outputs, belonging to the LVT logic series. It features a single-ended input and non-inverting polarity, housed in a TSSOP-20 surface-mount package. The device operates within a supply voltage range of 2 V to 3.6 V and supports a maximum clock frequency of 150 MHz. Key electrical parameters include a propagation delay of 4.6 ns at 3.3 V with 50 pF load, output currents of 32 mA high and 64 mA low, and a static current of 190 µA. It functions across a temperature range of -40°C to +85°C.

Feature Summary

• Octal D-type edge-triggered flip-flop architecture with three-state outputs
• High-speed operation supporting up to 150 MHz clock frequencies
• Robust drive capability with 64 mA low-level output current
• Compatible with standard 3.3 V logic systems

Applications

• Parallel-to-serial data conversion circuits
• I/O buffering for microprocessor interfaces
• Register storage in digital signal processing systems
• Clock domain crossing synchronization

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for recent Product Change Notices (PCN) regarding assembly materials or packaging updates. Ensure the specific suffix matches required reel specifications for automated placement processes.

Selection Notes

Select this component when requiring high-drive current capabilities alongside fast switching speeds in a compact surface-mount form factor. Consider the LVT series characteristics for compatibility with 3.3 V logic families. Evaluate thermal management requirements given the TSSOP-20 package constraints and operating temperature range limits.

Part Context

This part belongs to the 74LVT family of octal latches and flip-flops designed for low-voltage applications. It shares pinout compatibility with other 74-series logic devices but offers enhanced performance metrics suitable for modern digital systems requiring faster response times and higher noise immunity compared to standard HC or LV families.

Replacement Considerations

Public confirmed substitute part numbers: SN74LVTH574PW, SN74LVTH574PWR, SN74LVTH574IPWREP.
