74AHC126BQ,115

Buffers, Drivers, Receivers, Transceivers Overview

The 74AHC126BQ,115 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. The device incorporates Schmitt-trigger action on all inputs and provides overvoltage tolerance up to 5.5 V, facilitating use in mixed-voltage environments. It is housed in a DHVQFN14 package (SOT762-1) with dimensions of 2.5 x 3 x 0.85 mm.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad non-inverting buffer with three-state control is required. Ensure the application utilizes CMOS input levels compatible with the AHC series. Confirm that the DHVQFN14 package fits the PCB layout constraints and thermal requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC family of high-speed Si-gate CMOS devices. It is functionally equivalent to the standard 74AHC126 but packaged in the leadless DHVQFN14 format. It serves as a direct replacement for other quad buffers requiring three-state functionality in compact surface-mount designs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes include the 74AHCT126BQ,115 for TTL input levels. Other packages such as SO14 (74AHC126D) or TSSOP14 (74AHC126PW) offer identical electrical performance but different physical footprints.
