SN74HC574DWRE4

Flip Flops Overview

The SN74HC574DWRE4 is an octal edge-triggered D-type flip-flop with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 28 MHz. The device features a propagation delay of 22 ns, with high-level output current of -7.8 mA and low-level output current of 7.8 mA. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in a 20-pin SOIC package.

Flip Flops Feature Summary

• Octal edge-triggered D-type flip-flop architecture
• Three-state non-inverting outputs for bus driving
• Wide supply voltage compatibility from 2 V to 6 V

Flip Flops Applications

• Buffer registers
• I/O ports
• Bidirectional bus drivers
• Working registers

Flip Flops Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and environmental compliance as per manufacturer standards. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the 2 V to 6 V operating voltage aligns with your system power rails. Check that the 28 MHz maximum clock frequency meets your timing constraints. Validate RoHS compliance documentation for regulatory adherence.

Flip Flops Selection Notes

Select this component when an octal storage element with tri-state control is required for bus-oriented systems. The HC logic family offers standard CMOS performance suitable for general-purpose digital applications. Consider the 20-pin SOIC package for surface-mount assembly needs. Verify input compatibility with your logic family voltages. Evaluate the 22 ns propagation delay against your system speed requirements.

Flip Flops Part Context

This part belongs to the SN74HC574 series of octal edge-triggered D-type flip-flops. The 'DWR' designation specifies the 20-pin SOIC surface-mount package. The 'E4' suffix typically denotes lead-free packaging and environmental compliance. It is part of the broader 74HC logic family designed for high-speed CMOS operations.

Flip Flops Replacement Considerations

SN74HC574DR is a compatible alternative with identical electrical characteristics but may differ in packaging or compliance markings. SN74HC574N serves as a through-hole equivalent option. Verify pinout compatibility before substitution.
