SN74LVC74AWBQARQ1

Flip Flops Overview

The SN74LVC74AWBQARQ1 is an automotive-grade dual positive-edge-triggered D-type flip-flop from Texas Instruments, designed for reliable operation in demanding environments. It operates within a supply voltage range of 2 V to 3.6 V and supports mixed-mode voltage operation across all ports. The device features Ioff circuitry to prevent destructive back-current during partial power-down scenarios. Packaged in a compact WQFN-14 format, it ensures robust performance with high ESD protection capabilities exceeding JESD 22 standards.

Flip Flops Feature Summary

• Dual positive-edge-triggered D-type flip-flops with independent clock, set, reset, and data inputs
• Supports mixed-mode voltage operation on all ports for flexible system integration
• Includes Ioff circuitry to disable outputs and prevent back-current during local power-down
• High ESD protection performance exceeding JESD 22 standard requirements

Flip Flops Applications

• Programmable logic controllers (PLCs)
• DCS and PAC analog input modules
• AV receivers and set-top boxes
• Server motherboards and power supply units

Flip Flops Procurement Notes

Verify the specific suffix 'WBQARQ1' against the official Texas Instruments datasheet to confirm package type, tape-and-reel specifications, and automotive qualification status. Ensure compatibility with your PCB footprint and reflow soldering profile. Cross-reference the AEC-Q100 grade requirements with your system's environmental operating conditions before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when designing automotive systems requiring dual D-type storage elements within a low-voltage 2 V to 3.6 V domain. It is suitable for applications needing mixed-voltage interface capabilities and protection against back-current during partial power-down states. Consider the WQFN-14 package constraints for space-limited designs requiring surface-mount installation.

Flip Flops Part Context

This part belongs to the SN74LVC74A-Q1 family of automotive-grade logic devices. It complements other components like the SN74LVC00AWBQARQ1 NAND gates and SN74LV164AQWBQARQ1 shift registers within Texas Instruments' automotive logic portfolio. The series is designed to meet stringent automotive reliability standards while providing versatile digital logic functions.

Flip Flops Replacement Considerations

Check for direct pin-compatible alternatives within the SN74LVC74A-Q1 family or equivalent automotive-grade dual D-flip-flops from other manufacturers. Verify that any substitute maintains the same 2 V to 3.6 V operating range, WQFN-14 package dimensions, and Ioff functionality to ensure seamless integration without redesign.
