74LVC574AT20-13

Overview

The Diodes Incorporated 74LVC574AT20-13 is an octal D-type flip-flop featuring three-state outputs, manufactured in the LVC logic series. It operates within a supply voltage range of 1.65 V to 3.6 V and utilizes a 20-TSSOP surface-mount package. The device contains eight independent D-type circuits with clock inputs and non-inverting outputs. Key electrical specifications include a propagation delay of 3.8 ns at 3.3 V, with high-level and low-level output currents rated at -24 mA and 24 mA respectively. It supports industrial temperature ranges from -40°C to +125°C.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage
• Three-state outputs enabling direct bus-driven connections without external buffers
• CMOS technology ensuring low power consumption and compatibility with standard logic levels

Applications

• Parallel-to-serial data conversion interfaces

• Bus-oriented memory buffering

Procurement Notes

Verify the specific suffix AT20-13 against official Diodes Incorporated documentation to confirm the TSSOP-20 package and reel packaging details. Ensure that the ordering information matches the exact part number required for your bill of materials, as variations may exist regarding tape-and-reel quantities or RoHS compliance status. Cross-reference manufacturer datasheets for any recent updates to pin configurations or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring octal storage with tri-state capability under low-voltage conditions between 1.65 V and 3.6 V. The 3.8 ns propagation delay makes it suitable for moderate-speed digital logic applications. Consider the 20-TSSOP package dimensions for PCB layout constraints and verify that the 24 mA drive current meets the load requirements of the connected circuitry without exceeding thermal limits.

Part Context

This component belongs to the 74LVC574 family of octal D-type flip-flops produced by Diodes Incorporated. It is part of the broader LVC (Low Voltage CMOS) logic series, designed for high-speed operation with low power dissipation. The device serves as a fundamental building block for sequential logic circuits, offering reliable data retention and transfer capabilities in modern electronic designs.

Replacement Considerations
