SN74LV1T126QDBVRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV1T126QDBVRQ1 is an automotive-grade single buffer gate with three-state outputs and integrated voltage translation. It operates on a single supply voltage ranging from 1.6 V to 5.5 V. The device supports up-translation from lower voltage CMOS inputs (e.g., 1.2 V, 1.8 V) and down-translation from higher voltage inputs (up to 5.5 V tolerant). It achieves data rates of up to 150 Mbps at 3.3 V or 5 V supplies. The component meets AEC-Q100 Grade 1 standards for operation between -40°C and +125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm that the DBV (SOT-23-5) variant aligns with your PCB footprint requirements. Ensure the procurement channel provides documentation confirming AEC-Q100 compliance for automotive integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with bidirectional voltage translation is required in a space-constrained design. It is suitable for interfacing low-voltage logic with standard 3.3 V or 5 V systems. Consider the thermal resistance metrics if operating near maximum junction temperatures in enclosed automotive environments.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle voltage translation?

The SN74LV1T126-Q1 uses LVxT enhanced input thresholds to support up-translation from lower voltages and 5.5-V tolerant inputs for down-translation. The output voltage always references the VCC supply.

What is the function of the OE pin?

The OE (Output Enable) pin controls the three-state output. Applying a Low signal places the output into a high-impedance state, effectively disconnecting it from the circuit.
