74AHCT126BQ,115

Buffers, Drivers, Receivers, Transceivers Overview

The 74AHCT126BQ,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 4.5 V to 5.5 V. The device incorporates Schmitt-trigger action on all inputs and provides overvoltage tolerance up to 7.0 V, facilitating translation in mixed-voltage environments. It is housed in a DHVQFN14 package (SOT762-1) with dimensions of 2.5 mm x 3 mm x 0.85 mm.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible input levels are required at 5 V operation. The DHVQFN14 package offers a compact footprint suitable for space-constrained designs. Ensure the application environment remains within the specified -40 °C to +125 °C temperature range for optimal performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHCT logic family, which bridges CMOS technology with TTL input compatibility. The 'BQ' designation indicates the DHVQFN14 leadless package variant. It serves as a non-inverting buffer counterpart to other logic families, providing high-speed signal integrity for digital systems operating at standard 5 V logic levels.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements include the 74AHC126BQ,115 for CMOS-level inputs or the 74VHCT126BQ for high-speed applications. Verify that the substitute maintains the same DHVQFN14 package outline and thermal characteristics.
