SN74LVC125AWBQARQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125AWBQARQ1 is an automotive-grade quadruple bus buffer gate with 3-state outputs, designed for 1.65V to 3.6V VCC operation. It features independent line drivers where each output is disabled when the associated OE input is high. The device operates from –40°C to 125°C and accepts inputs up to 5.5V. At 3.3V, it achieves a maximum propagation delay of 4.8ns. Latch-up performance exceeds 250mA per JESD 17.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific BQA package variant matches the design requirements. Confirm RoHS compliance and lead finish details via the latest orderable information addendum. Ensure ESD precautions are observed during handling. Validate suitability for safety-critical applications as per TI disclaimers.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 3-state bus buffers in automotive environments. It supports mixed voltage interfaces by accepting 5V inputs while operating on lower supply rails. Verify thermal resistance values for the WQFN package if heat dissipation is a concern.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC125A-Q1 family of automotive quadruple bus buffer gates. It shares functional characteristics with other variants like SN74LVC125AQDRQ1 but differs in packaging. The BQA suffix indicates a WQFN-14 package configuration.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused inputs?

All unused inputs must be connected to a high or low bias, typically VCC or GND, to prevent undefined operational states caused by floating voltages.

What is the recommended bypass capacitor value?

A 0.1 μF capacitor is recommended for single-supply devices, placed as close to the power pin as possible. For multiple VCC pins, 0.01 μF or 0.022 μF per pin is suggested.
