MC74AC574DWG

Flip Flops Overview

The MC74AC574DWG is an octal D-type flip-flop manufactured by onsemi, belonging to the 74AC logic series. It features a single element with eight bits per element, housed in a 20-SOIC surface-mount package. The device operates on a supply voltage ranging from 2V to 6V and supports a maximum clock frequency of 95 MHz. Key electrical parameters include a maximum propagation delay of 13.5 ns, output currents of 24mA for both high and low states, and a static current consumption of 8 µA. It functions as a positive-edge triggered device with tri-state, non-inverting outputs.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type storage elements within a single integrated circuit.
• Positive-edge triggering mechanism ensures data capture occurs at the rising edge of the clock signal.
• Tri-state output capability allows for bus-oriented memory applications by enabling high-impedance states.
• CMOS construction delivers standard performance characteristics typical of the 74AC logic family.

Flip Flops Applications

• Bus-oriented memory register implementations
• Eight-bit position counters
• Parallel-to-serial data conversion circuits

Flip Flops Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeit risks. Confirm RoHS compliance status matches specific project requirements, as historical variants may differ. Ensure the 20-SOIC footprint aligns with PCB design constraints. Validate that the 2V to 6V operating range suits the target system voltage levels before integration.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with tri-state outputs is required for bus systems. The 74AC series offers faster switching speeds compared to HC counterparts. Consider the 20-SOIC package for surface-mount assembly needs. Verify that the 95 MHz clock limit meets the application timing requirements. Check alternative packages like TSSOP if space constraints dictate a smaller form factor.

Flip Flops Part Context

This part belongs to the 74AC574 family of octal D-type flip-flops. It shares functional similarities with other 74AC logic devices but is distinct in its eight-bit width and tri-state output configuration. The DWG suffix indicates a specific tube packaging variant produced by onsemi, differentiating it from tape-and-reel versions or other manufacturers' equivalents.

Flip Flops Replacement Considerations

MC74AC574DWG is a direct replacement for MC74AC574DW. SN74AC574DWR from Texas Instruments serves as a compatible alternative. CD74AC574M96 from Texas Instruments is another verified substitute option.
