MM74HC574N

Flip Flops Overview

The MM74HC574N is a 3-State Octal D-Type Edge-Triggered Flip-Flop manufactured by onsemi. It operates within a supply voltage range of 2 V to 6 V and features single-ended inputs and outputs. The device provides non-inverting logic with a propagation delay of 265 ns. It supports high-level output currents of -7.8 mA and low-level output currents of 7.8 mA. Designed for surface-mount or through-hole applications, it functions reliably across an operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Octal D-type edge-triggered flip-flop architecture
• Three-state output capability for bus driving
• Non-inverting logic polarity

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register storage in microprocessor systems
• Buffering and latching digital signals

Flip Flops Procurement Notes

Verify the package type matches the required application, as the 'N' suffix typically indicates a PDIP-20 through-hole configuration. Confirm RoHS compliance status via official documentation before integration. Ensure supply voltage limits remain within the specified 2 V to 6 V range during operation. Check for any specific handling requirements related to electrostatic discharge protection during assembly.

Flip Flops Selection Notes

Select this component when an octal register with three-state outputs is required for HC logic families. It is suitable for designs needing non-inverting data storage with moderate speed performance. Consider the 265 ns propagation delay against system timing constraints. Verify that the through-hole packaging aligns with the PCB layout and manufacturing process capabilities.

Flip Flops Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It serves as a fundamental building block for sequential logic circuits requiring parallel data retention. The octal configuration allows for efficient management of multiple data lines within a single integrated circuit package.

Flip Flops Replacement Considerations

SN74HC574NE4 is a confirmed substitute part number from Texas Instruments offering equivalent functionality.
