74AHC244BQ-Q100,11

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC244BQ-Q100,11 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.0 V to 5.5 V and is qualified to AEC-Q100 Grade 1 standards for automotive applications. The device utilizes a DHVQFN20 package (SOT764-1) with dimensions of 2.5 mm x 4.5 mm x 0.85 mm. It includes two output enable inputs controlling four outputs each, overvoltage tolerant inputs up to 5.5 V, and Schmitt-trigger action on all inputs.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration. Confirm that the DHVQFN20 package variant aligns with the intended PCB footprint and thermal management requirements. Ensure the component meets the necessary AEC-Q100 Grade 1 reliability standards for the target automotive application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state outputs is required for automotive-grade designs. The wide supply voltage range supports various logic levels. The DHVQFN package offers a compact solution suitable for space-constrained boards while maintaining robust thermal performance through side-wettable flanks.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC244-Q100 family of octal buffers. It shares functional characteristics with other variants like the 74AHCT244BQ-Q100 but differs in input logic levels and package options. The BQ suffix specifically denotes the DHVQFN20 package type, distinguishing it from SO or TSSOP versions within the same logical series.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other 74AHC244 variants in the DHVQFN20 package, such as the non-automotive 74AHC244BQ. Cross-family replacements require verification of voltage compatibility and pin alignment.
