SN74LVC574DBLE

Flip Flops Overview

The SN74LVC574DBLE is an octal edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a voltage range of 2.7 V to 3.6 V. The device features low input capacitance and supports high-speed data transfer. It is housed in a 20-SSOP package with a shrink pitch, designed for surface-mount applications. The component includes master reset functionality and non-inverting outputs, ensuring reliable signal integrity in digital logic circuits.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops with edge-triggered operation
• 3-state output capability allowing direct connection to bus lines without external drivers
• Low input capacitance design minimizing loading effects on driving sources
• Master reset function enabling synchronous clearing of all flip-flop states

Flip Flops Applications

• High-speed data buffering and latching in communication systems
• Register files in microprocessor-based architectures
• Bus interface circuits requiring tri-state control
• Digital signal processing data path storage elements

Flip Flops Procurement Notes

Verify the complete part number including the DBLE suffix to ensure correct SSOP shrink pitch packaging. Confirm that the supply voltage matches the specified 2.7-V to 3.6-V operating range. Check datasheet revisions for any updates to electrical characteristics or recommended operating conditions. Ensure compatibility with existing PCB footprint and thermal management requirements during integration.

Flip Flops Selection Notes

Choose this component when an octal register with tri-state outputs is required for 3.3-V logic systems. Consider the 20-SSOP package for space-constrained surface-mount designs. Evaluate propagation delay specifications against system timing requirements. Verify that input voltage levels are compatible with the source logic family to prevent signal integrity issues.

Flip Flops Part Context

This device belongs to the LVC (Low Voltage CMOS) series from Texas Instruments, optimized for low-power applications in portable electronics. The SN74LVC574 variant provides a standard octal flip-flop solution, while the DBLE suffix denotes the specific 20-lead shrink small-outline package. It complements other LVC logic devices for consistent system-level performance.

Flip Flops Replacement Considerations

SN74LVC574D is a pin-compatible alternative in standard SSOP packaging. SN74LVC574DR offers tape-and-reel packaging for automated assembly. SN74ACT574 provides similar functionality but operates at 5-V logic levels, requiring voltage level translation if used in 3.3-V systems.
