SN74HC574NS

Flip Flops Overview

The SN74HC574NS is an octal edge-triggered D-type flip-flop with three-state outputs manufactured by Texas Instruments. It belongs to the 74HC logic family and operates within a supply voltage range of 2V to 6V. The device features non-inverting outputs and supports a maximum clock frequency of 40 MHz. Propagation delay is specified at 31ns @ 6V, 50pF. It utilizes a 20-SOIC package (0.209 inch width) for surface mount installation. The component functions as a buffer register or I/O port interface.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single integrated circuit
• Three-state output capability allowing direct connection to bus-oriented systems without internal loading
• Edge-triggered data storage synchronized with positive clock transitions for precise timing control

Flip Flops Applications

• Buffer registers for temporary data storage in digital circuits
• I/O ports for interfacing microprocessors with peripheral devices
• Bus drivers for managing signal transmission across shared communication lines

Flip Flops Procurement Notes

Verify the specific suffix 'NS' against the manufacturer's official documentation to confirm the exact package type and tape/reel specifications. Ensure the ordering part number matches the required pinout and thermal characteristics. Cross-reference the datasheet revision date to guarantee compatibility with current design standards and regulatory requirements before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring high-speed data latching with minimal propagation delay. The 74HC series offers low power consumption suitable for battery-operated applications. Consider the 20-SOIC package dimensions for PCB layout constraints. Verify that the operating voltage range aligns with the system's power supply rails and that the load capacitance does not exceed the specified limits for optimal performance.

Flip Flops Part Context

This device is part of the broader SN74HC574 family, which includes variants with different packaging options such as PDIP, TSSOP, and SOIC. The NS suffix specifically denotes the small-outline package variant. It shares functional similarities with other octal flip-flops but is distinguished by its specific speed characteristics and output drive capabilities defined by the HC technology node.
