SN74HC574NE4

Flip Flops Overview

The SN74HC574NE4 is an octal edge-triggered D-type flip-flop from the Texas Instruments HC logic family, housed in a 20-pin PDIP package. It features non-inverting outputs with three-state capability and operates on a single-ended CMOS input. The device supports a supply voltage range of 2V to 6V, with a maximum propagation delay of 265ns at lower voltages and 57ns at higher voltages under specific load conditions. It provides output drive currents of ±7.8mA and functions within a temperature range starting from -40°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent edge-triggered D-type flip-flops within a single integrated circuit.
• Three-state output architecture allowing direct bus-oriented connections without external buffer drivers.
• CMOS technology ensuring low static power consumption and high noise immunity for reliable digital operation.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose register storage applications
• Bus-oriented memory systems

Flip Flops Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official datasheet specifications. Confirm the package type matches the required PCB footprint and ensure the operating temperature range meets system environmental requirements. Cross-reference the ordering suffix to confirm lead-free compliance status as indicated in the product documentation.

Flip Flops Selection Notes

Select this component when an octal storage element with tri-state control is required for bus-based architectures. Ensure the system voltage falls within the specified 2V to 6V range to maintain signal integrity. Consider the propagation delay characteristics relative to the clock frequency requirements of the target application design.

Flip Flops Part Context

This part belongs to the SN74HC574N series, representing the standard industrial-grade variant of the octal D-type flip-flop. The NE4 suffix typically denotes a lead-free and RoHS-compliant manufacturing version of the standard PDIP-20 package offered by Texas Instruments for through-hole mounting applications.

Flip Flops Replacement Considerations

Direct functional equivalents include the SN74HC574N and SN74HC574NSR. Verify pin compatibility and electrical specifications before substitution. Package differences between PDIP and SOIC variants require mechanical adaptation during replacement.
