SN74HC574DWR

Flip Flops Overview

The SN74HC574DWR is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 2 V to 6 V. The device utilizes HC CMOS technology, providing low static power consumption with a maximum ICC of 80 µA at nominal voltage. It offers non-inverting logic polarity and supports surface-mount installation in a 20-SOIC package. The component is rated for operation between -40 °C and +85 °C, ensuring reliability across industrial temperature ranges.

Flip Flops Feature Summary

• Octal configuration containing eight independent positive-edge-triggered D-type flip-flops
• Three-state outputs designed for direct bus driving applications
• Low static power consumption characteristic of HC CMOS technology
• Wide operating voltage range supporting both 3.3 V and 5 V systems

Flip Flops Applications

• Buffer registers for data storage and isolation
• I/O port expansion in embedded systems
• Bidirectional bus driver implementations
• Working registers in digital control circuits

Flip Flops Procurement Notes

Verify the specific suffix 'DWR' confirms the SOIC-20 surface-mount package and tape-and-reel shipping format. Confirm RoHS compliance status matches current manufacturing standards. Ensure the ordering part number aligns with the required lead times and availability from authorized distributors. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines.

Flip Flops Selection Notes

Select this component when an octal register with high-impedance states is required for bus architectures. The HC series provides a balance of speed and power efficiency suitable for general-purpose logic. Verify that the 2 V to 6 V supply range matches the system voltage rails. Consider the 20-SOIC footprint for PCB layout constraints compared to other package options.

Flip Flops Part Context

This device belongs to the SN74HC574 family of octal D-type flip-flops. It shares functional similarities with variants like SN74HC574AN but differs in packaging and mounting style. The DWR suffix specifically denotes the wide-body SOIC package optimized for automated surface-mount assembly processes.

Flip Flops Replacement Considerations

SN74HC574DR is a compatible alternative offering identical electrical characteristics in the same SOIC-20 package format. Both parts maintain the octal D-type flip-flop functionality with three-state outputs.
