• Schmitt-trigger action at all inputs ensures tolerance against slow input rise and fall times

Applications

• Automotive infotainment systems requiring robust data latching
• Industrial control modules utilizing serial-to-parallel data conversion
• Consumer electronics interfaces needing high-speed memory buffering
• General-purpose digital logic circuits requiring asynchronous reset capabilities

Procurement Notes

Verify the specific suffix 'X' indicates the tape-and-reel packaging format as documented by the manufacturer. Confirm that the AEC-Q100 qualification grade matches the required automotive reliability standards for the target application environment. Ensure compatibility with the DHVQFN-20 footprint during PCB layout validation. Cross-reference the official datasheet revision to confirm pinout consistency and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when an octal flip-flop solution is required for automotive or industrial applications demanding high noise immunity. The Schmitt-trigger inputs make it suitable for environments with slow signal transitions. Consider the DHVQFN-20 package size constraints and thermal dissipation requirements. Verify that the 1.2 V to 3.6 V supply range aligns with the system's power architecture and that the three-state outputs meet the bus driving needs of the design.

Part Context

This part belongs to the Nexperia 74LVC family of low-voltage CMOS logic devices, specifically tailored for automotive and general-purpose applications. The 'ABQ' designation typically refers to the specific variant with enhanced specifications and the Q100 suffix denotes automotive qualification. It serves as a critical building block for sequential logic circuits, offering compact integration for multiple flip-flops in a single surface-mount package.

Replacement Considerations

Direct replacements must maintain the octal D-flip-flop topology, three-state output capability, and AEC-Q100 automotive qualification. Verify pinout compatibility with the SOT764 (DHVQFN-20) package to ensure seamless board replacement. Check that alternative components support the same 1.2 V to 3.6 V operating voltage range and Schmitt-trigger input characteristics to preserve circuit functionality.
