SN74LVC574ADGVRE4

Flip Flops Overview

The SN74LVC574ADGVR-E4 is an octal D-type flip-flop with three-state outputs from Texas Instruments' LVC series. It operates within a 1.65V to 3.6V supply range and features a propagation delay of 7.8ns at 3.3V. The device provides 24mA output drive current and accepts CMOS or TTL inputs. Packaged in a 20-TSSOP, it supports edge-triggered data storage for digital logic applications.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with eight independent data paths
• Three-state outputs allowing direct bus connection without external drivers
• CMOS and TTL input compatibility for flexible system integration

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register files in microprocessor-based systems
• Buffering and latching in communication interfaces

Flip Flops Procurement Notes

Verify the -E4 suffix indicates environmental compliance per manufacturer standards. Confirm the TSSOP-20 package matches PCB footprint requirements. Ensure voltage levels align with the 1.65V to 3.6V operational range. Check temperature ratings against application environment constraints.

Flip Flops Selection Notes

Select this component when low-voltage operation and high-speed performance are required. The LVC series offers faster switching than standard HC logic while maintaining lower power consumption. Consider the 24mA drive capability for moderate load conditions. Verify that the TSSOP-20 package fits available board space.

Flip Flops Part Context

This part belongs to the SN74LVC574A family of octal flip-flops. The -E4 suffix denotes RoHS-compliant manufacturing. It shares functional compatibility with other LVC series devices but differs in package type and specific electrical characteristics compared to non-E4 variants.

Flip Flops Replacement Considerations

SN74LVC574ADGVR is the primary equivalent without the environmental suffix. SN74LVC574APWR offers the same function in a TSSOP-20 package. SN74LVC574ADBR provides identical logic in a smaller SSOP-20 package.
