74AHC126BQ-Q100,11

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC126BQ-Q100,11 is a quad buffer and line driver featuring three-state outputs controlled by active-high output enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device utilizes a DHVQFN14 package (SOT762-1) with dimensions of 2.5 mm x 3 mm x 0.85 mm. Inputs are overvoltage tolerant, allowing compatibility in mixed-voltage environments.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel packaging configuration. Confirm that the component version aligns with the latest product data sheet revision to ensure accurate electrical specifications and package outline dimensions. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when automotive-grade reliability is mandatory for the target application. Choose this variant specifically for its compact DHVQFN footprint which includes side-wettable flanks for enhanced manufacturing inspection capabilities. Ensure the system design accommodates the specified operating temperature range and supply voltage requirements defined in the recommended operating conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Nexperia 74AHC126-Q100 family of quad buffers and line drivers. It shares functional characteristics with other members of the series but is distinguished by its specific DHVQFN14 package type. The family provides standardized logic functions tailored for robust performance in demanding industrial and automotive environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the 74AHC126D-Q100 and 74AHC126PW-Q100 variants. These alternatives offer identical logical functionality but utilize SO14 or TSSOP14 packages respectively. Verify pinout compatibility and thermal dissipation requirements when transitioning between these package types.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the nOE input control the output state?

When the nOE input is LOW, the outputs assume a high-impedance OFF-state regardless of the input signals. When nOE is HIGH, the outputs follow the respective data inputs.

What is the significance of the side-wettable flanks in the DHVQFN package?

The side-wettable flanks allow solder to wet the vertical sides of the terminals, enabling Automatic Optical Inspection (AOI) systems to verify the quality of the solder joints effectively.
