74AHCT125BQ,115

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT125BQ,115 is a quad buffer and line driver featuring three-state outputs controlled by active LOW output enable inputs (nOE). It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes TTL input levels. The device provides balanced propagation delays and high noise immunity. It is housed in a DHVQFN14 package (SOT762-1) with dimensions of 2.5 mm x 3 mm x 0.85 mm. The component supports an ambient temperature range from -40 °C to +125 °C and includes Schmitt-trigger action on all inputs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible inputs are required for 5 V logic systems. The DHVQFN14 package offers a compact footprint suitable for space-constrained designs. Ensure the application voltage remains within the 4.5 V to 5.5 V range to maintain specified electrical performance and timing parameters.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC/AHCT logic family, which combines the high speed of AHC technology with the TTL-compatible input thresholds of AHCT devices. The BQ suffix indicates the DHVQFN14 leadless package variant. This series is designed for general-purpose digital applications requiring robust signal integrity and low power consumption in standard 5 V logic environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements include other manufacturers' 74AHCT125 variants in the DHVQFN14 package. Verify that substitute components meet the same DHVQFN14 mechanical outline (SOT762-1) and electrical specifications for 5 V operation.
