74LVTH574WMX

Overview

The onsemi 74LVTH574WMX is an octal D-type flip-flop with three-state outputs, belonging to the LVTH logic series. It operates within a supply voltage range of 2.7V to 3.6V and features a propagation delay of 5.3ns. The device provides high drive capabilities with output currents of -32mA (high) and 64mA (low). Packaged in TSSOP-20 for surface mount installation, it supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Octal D-type edge-triggered flip-flop architecture
• Three-state non-inverting outputs
• High current drive capability for direct bus driving
• TTL-compatible input thresholds

Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register storage
• Clock domain crossing synchronization
• General-purpose digital signal processing interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to procurement. Ensure storage conditions meet moisture sensitivity level requirements to prevent package damage during soldering processes.

Selection Notes

Select this component when TTL-level compatibility is required alongside low-voltage operation. The LVTH series bridges standard TTL inputs with CMOS outputs, suitable for mixed-signal environments. Consider the specific drive current requirements and package constraints compared to alternative logic families like LVT or HC.

Part Context

This part belongs to the 74LVTH574 family of octal flip-flops. It shares functional similarities with other variants such as 74LVTH574MTCX but differs in packaging configuration. The WMX suffix indicates a tape-and-reel surface-mount package variant designed for automated assembly processes.
