SN74LVC374AQDWRQ1

Flip Flops Overview

The SN74LVC374AQDWRQ1 is an automotive-grade octal edge-triggered D-type flip-flop featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2.0 V to 3.6 V and supports a maximum clock frequency of 200 MHz. The device provides high drive capability with low-level output currents up to 24 mA and high-level output currents up to -12 mA. It is housed in a 20-pin TSSOP package and is qualified under AEC-Q100 standards for operation across a temperature range of -40°C to +125°C.

Flip Flops Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Octal configuration providing eight independent D-type flip-flops with positive-edge triggering.
• Three-state outputs enable direct bus connections without additional interface logic.
• Supports mixed 3.3-V and 5-V I/O environments through compatible input structures.

Flip Flops Applications

• Automotive data acquisition systems requiring reliable digital storage.
• Bus-oriented memory address register applications in vehicle electronics.
• General-purpose parallel-to-serial conversion circuits in automotive modules.
• I/O expansion solutions for microcontrollers in connected car architectures.

Flip Flops Procurement Notes

Verify the specific suffix 'QDWR' confirms the TSSOP-20 package and automotive grade. Confirm AEC-Q100 qualification status matches project requirements. Check RoHS compliance documentation for environmental regulations. Ensure operating voltage limits align with system power rails. Validate temperature range specifications against target deployment conditions.

Flip Flops Selection Notes

Select this component when designing automotive logic circuits requiring octal storage with bus-compatible outputs. The LVC series offers lower power consumption compared to older LV technologies while maintaining robust drive strength. Consider the 200 MHz speed limit for high-frequency clock applications. The TSSOP-20 package facilitates surface-mount assembly in space-constrained automotive PCB layouts.

Flip Flops Part Context

This device belongs to the SN74LVC374-Q1 family of automotive octal flip-flops. It shares functional compatibility with non-automotive SN74LVC374A variants but includes enhanced testing for automotive reliability. The Q1 suffix denotes automotive qualification, distinguishing it from standard commercial grade parts within the broader 74LVC logic portfolio.
