NLV74HC574ADWR2G

Flip Flops Overview

The NLV74HC574ADWR2G is an octal D-type flip-flop manufactured by onsemi, belonging to the HC logic family. It features positive-edge triggering and non-inverting outputs with three-state capability. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports a maximum clock frequency of 35 MHz. Key electrical parameters include a propagation delay of 160 ns, output drive currents of ±7.8 mA, and low static current of 4 µA. It is housed in a 20-SOIC package and functions identically to the standard MC74HC574ADWR2G.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with positive-edge clock triggering for data storage
• Three-state output control allowing high-impedance states for bus line management
• CMOS input compatibility with LSTTL interface support via pull-up resistors
• Wide operating voltage range supporting 2.0 V to 6.0 V power supplies

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register implementations
• Clock domain crossing synchronization stages
• General-purpose digital data storage applications

Flip Flops Procurement Notes

Verify that the NLV74HC574ADWR2G designation corresponds to the automotive-grade variant of the standard MC74HC574ADWR2G. Confirm RoHS compliance and moisture sensitivity level (MSL 3) requirements for your manufacturing process. Ensure the SOIC-20 footprint matches your PCB design constraints before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with three-state outputs is required for systems operating between 2.0 V and 6.0 V. It is suitable for designs needing high noise immunity and direct CMOS interfacing. Consider the 160 ns propagation delay for timing analysis. Use this part if automotive-grade reliability or specific onsemi packaging variants are necessary compared to standard industrial versions.

Flip Flops Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices produced by onsemi. It shares functional pinout compatibility with the older 74LS574 but offers improved power efficiency and wider voltage operation. The device is designed for general-purpose digital logic applications requiring reliable data latching and bus driving capabilities in compact surface-mount packages.

Flip Flops Replacement Considerations

The MC74HC574ADWR2G is the standard commercial equivalent. For TSSOP-20 packaging, consider the MM74HC574MTC. Verify that any substitute maintains the same 20-SOIC footprint and three-state functionality.
