MM74HC574WM

Flip Flops Overview

The MM74HC574WM is a D-Type Edge Triggered Flip-Flop from the HC logic series, manufactured by Fairchild Semiconductor. It integrates eight independent circuits within a single package. The device features single-ended inputs and outputs with non-inverting polarity. It operates on a supply voltage ranging from 2 V to 6 V. The component supports surface mount installation in a 20-SOIC (0.295", 7.50mm Width) package. It provides high-level output current of -7.8 mA and low-level output current of 7.8 mA. The propagation delay is specified at 155 ns. The operational temperature range extends from -40 °C to +85 °C.

Flip Flops Feature Summary

• Integrates eight independent D-type edge-triggered flip-flops for parallel data storage
• Features three-state outputs allowing direct bus line connections without external buffers
• Supports wide supply voltage operation from 2V to 6V for flexible system integration

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in digital systems
• Data buffering between microprocessors and peripheral devices

Flip Flops Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or its successor entity, as corporate acquisitions may affect branding on datasheets and components. Confirm the package specification matches the 20-SOIC form factor with the stated 7.50mm width. Ensure the logic family corresponds to standard HC specifications rather than HCT variants which require different voltage thresholds. Cross-reference RoHS compliance status with current environmental declarations provided by the supplier.

Flip Flops Selection Notes

Select this component when eight synchronized storage elements are required in a compact surface-mount footprint. The HC series offers standard CMOS performance suitable for general-purpose digital logic applications. Consider the 155 ns propagation delay against system timing requirements. Verify that the 2V to 6V operating range aligns with the target power supply rails. Evaluate thermal management needs within the specified -40°C to +85°C ambient temperature limits.

Flip Flops Part Context

This part belongs to the widely adopted 74HC574 logic family, representing a standard octal D flip-flop configuration. It serves as a fundamental building block for sequential logic design in consumer electronics and industrial control systems. The SOIC-20 package provides a balance between pin count and board space efficiency compared to larger DIP packages.
