74AHC125BQ,115

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC125BQ,115 is a quad buffer and line driver featuring three-state outputs controlled by active-low output enable inputs. It operates within a supply voltage range of 2.0 V to 5.5 V and utilizes the DHVQFN14 package (SOT762-1). The device provides non-inverting logic with balanced propagation delays and Schmitt-trigger action on all inputs. It supports ambient temperatures from -40 °C to +125 °C and includes overvoltage tolerant inputs up to 5.5 V.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with three-state control is required for CMOS logic levels. Ensure the design accommodates the DHVQFN14 package dimensions and thermal requirements. Confirm that input signals remain within the specified overvoltage tolerance limits relative to the supply voltage.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC/AHCT125 family of quad buffers. It shares functional characteristics with other variants like the 74AHCT125 but differs in input switching levels, supporting CMOS rather than TTL levels. The BQ suffix specifically denotes the DHVQFN14 leadless package option.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other 74AHC125 variants with different packages such as 74AHC125D or 74AHC125PW. Cross-family substitutes like 74LVC125 or 74LVTH125 may be considered if voltage levels and drive strengths align with system requirements.
