SN74LVT574PWR

Flip Flops Overview

The SN74LVT574PWR is an octal D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It belongs to the LVT logic series and features a TSSOP-20 surface-mount package. The device operates within a supply voltage range of 2.7 V to 3.6 V. Key electrical parameters include a propagation delay of 4.3 ns, a high-level output current of -32 mA, and a low-level output current of unspecified in the provided table but implied as standard for the series. It supports non-inverting input polarity and single-ended inputs.

Flip Flops Feature Summary

• Octal edge-triggered D-type flip-flop architecture
• Three-state output capability for bus driving
• Compatible with TTL input levels

Flip Flops Applications

• Parallel-to-serial data conversion
• I/O port expansion
• Clock domain crossing buffers

Flip Flops Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating temperature range meets system requirements, specifically noting the -40°C to +85°C specification. Cross-reference the datasheet version to ensure accurate timing and electrical characteristics are applied during design.

Flip Flops Selection Notes

Select this component when an octal storage element with 3-state outputs is required for 3.3V logic systems. The LVT series offers compatibility with both LVCMOS and TTL input standards. Consider the TSSOP-20 package for space-constrained surface-mount designs. Verify that the 4.3 ns propagation delay satisfies the system's timing constraints compared to faster ABT or AHCT alternatives.

Flip Flops Part Context

This part is part of the SN74LVT574 family of octal D-type flip-flops. It shares functional similarities with other members like the SN74LVTH574 and SN74LVT574DWR, differing primarily in package type (TSSOP vs SOIC) and specific electrical characteristics defined by the LVT series. It serves as a standard solution for parallel data latching in digital logic applications.
