MC74LCX574DWR2

Flip Flops Overview

The MC74LCX574DWR2 is a low-voltage CMOS octal D-type flip-flop manufactured by onsemi. It operates within a supply voltage range of 2.3 V to 3.6 V and features five-volt tolerant inputs and outputs, enabling direct interfacing with 5.0 V logic devices. The component utilizes a 20-SOIC surface-mount package and includes an IOFF specification to ensure high-impedance states when power is removed. Designed for live insertion applications, it offers balanced 24 mA output drive capability and near-zero static supply current across all logic states.

Flip Flops Feature Summary

• Five-volt tolerant input and output interface capability for seamless integration with 5.0 V TTL logic systems
• IOFF specification ensures high-impedance state protection when the supply voltage is zero
• Supports live insertion and withdrawal operations without causing system damage or signal interference

Flip Flops Applications

• Interfacing between low-voltage logic circuits and 5.0 V TTL logic systems
• Data storage and buffering in portable electronic devices requiring low power consumption
• System control logic in applications supporting live hot-swap insertion scenarios

Flip Flops Procurement Notes

Verify that the specific part number matches the required voltage tolerance and package type for your design. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure handling procedures account for moisture sensitivity levels as specified in the datasheet to maintain component integrity during assembly.

Flip Flops Selection Notes

Select this component when designing systems that require bridging low-voltage logic domains with 5.0 V interfaces. Consider its suitability for applications demanding minimal static power dissipation and robust protection against accidental power removal. Evaluate the 20-SOIC package constraints against available PCB real estate and thermal management requirements for optimal performance.

Flip Flops Part Context

This device belongs to the LCX series of low-voltage CMOS logic products from onsemi. It is functionally similar to other octal D-type flip-flops but distinguished by its specific 2.3 V to 3.6 V operating range and five-volt tolerance. The DWR2 suffix indicates a reel-based tape and reel packaging format suitable for automated surface-mount assembly processes.

Flip Flops Replacement Considerations

MC74LCX574DW is a tube-packaged equivalent offering identical electrical characteristics. MC74LCX574DWR2G represents the same functional device with updated environmental compliance markings. Verify pinout compatibility and voltage specifications before substituting with alternative manufacturers' parts.
