CD74HC574M96G4

Overview

The CD74HC574M96G4 is an octal D-type flip-flop from the Texas Instruments HC logic family, housed in a 20-pin SOIC package. It features positive-edge triggering and three-state outputs for bus-oriented memory operations. The device operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -55 °C to +125 °C. Propagation delay is specified at 165 ns @ 2 V with a 50 pF load.

Feature Summary

• Octal D-type flip-flop architecture providing eight independent storage elements
• Positive-edge triggering mechanism synchronized by clock input
• Three-state outputs enabling direct bus connection without external buffers
• Wide operating voltage range supporting 2 V to 6 V supply rails

Applications

• Bus-oriented memory register implementations
• Parallel-to-serial data conversion circuits
• High-speed buffering applications requiring isolation
• Industrial control systems operating in extreme temperatures

Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm the SOIC-20 package variant matches your PCB footprint requirements. Check datasheet specifications for maximum operating temperature limits when designing for high-temperature industrial environments.

Selection Notes

Select this component for designs requiring octal storage with tri-state output control. Ensure the system voltage remains within the 2 V to 6 V operational window. Consider the 165 ns propagation delay at low voltages when calculating maximum clock frequencies for timing-critical paths.

Part Context

This device belongs to the CD74HC574 series of high-speed CMOS logic products. It shares functional similarities with other octal flip-flops but offers specific package and environmental ratings. The M96 suffix indicates a specific tape-and-reel packaging configuration suitable for automated surface-mount assembly processes.

Replacement Considerations

Compatible substitutes include SN74HC574PWRG4 and CD74HC574M96E4. Verify pinout compatibility and electrical characteristics before substitution. Ensure replacement parts meet the same voltage and temperature specifications.
