Procurement Notes

Verify the specific manufacturer part number against official STMicroelectronics documentation to ensure authenticity. Confirm that the component meets RoHS compliance standards required for your region. Check for any obsolescence notices or end-of-life status directly from the manufacturer before finalizing procurement plans. Ensure the TSSOP-20 package dimensions match your PCB footprint requirements precisely.

Selection Notes

Select this component when designing low-voltage digital circuits requiring octal data storage capabilities. Consider its 2 V to 3.6 V operating range for compatibility with modern low-power systems. Evaluate the 20-TSSOP package size against available board space constraints. Compare performance metrics such as propagation delay and output drive strength against alternative logic families if higher speed or different voltage levels are needed.

Part Context

This component belongs to the 74LVX series of low-voltage CMOS logic devices produced by STMicroelectronics. The series is characterized by high-speed operation and low power dissipation, making it suitable for portable and battery-operated applications. The 74LVX574 specifically provides octal D-type flip-flop functionality, distinguishing it from single-bit or smaller capacity variants within the same logical family.

Replacement Considerations

Direct substitutes may include equivalent octal D-type flip-flops from other manufacturers offering compatible pinouts and electrical specifications. Verify voltage ranges and package types carefully when considering alternatives. Cross-reference datasheets to ensure functional parity regarding output states and triggering mechanisms.
