SN74LV1T34QDCKRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV1T34QDCKRQ1 is an automotive-grade single buffer and logic level translator from Texas Instruments. It operates on a single power supply ranging from 1.6 V to 5.5 V. The device supports up-translation from input levels as low as 1.2 V to outputs of 1.8 V, 2.5 V, 3.3 V, or 5 V. It also facilitates down-translation from 5.0 V, 3.3 V, or 2.5 V inputs to lower voltage outputs. The component features 5.5 V tolerant input pins and balanced CMOS push-pull outputs. It is qualified under AEC-Q100 standards for Grade 1, supporting temperatures from -40°C to +125°C.

• AEC-Q100 qualified for automotive applications with extended temperature range
• Single-supply operation enabling bidirectional voltage translation between various CMOS levels
• Enhanced input voltage thresholds allowing up-translation from lower voltage sources
• 5.5 V tolerant input pins designed for down-translation applications

Buffers, Drivers, Receivers, Transceivers Applications

• Translation between communication modules and system controllers
• Enabling or disabling digital signals in automotive systems
• Controlling indicator LEDs via translated control signals

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the DCK designation indicates the SC-70 package. Confirm that the Q1 suffix aligns with the necessary automotive qualification requirements for the target application. Ensure the supply voltage provided to the VCC pin falls within the specified 1.6 V to 5.5 V operational range during design validation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with integrated level shifting is required in space-constrained designs. It is suitable for interfacing low-voltage microcontrollers with higher-voltage peripherals or vice versa. Consider the SC-70 package size if board real estate is limited. Verify that the load capacitance does not exceed recommended limits to maintain signal integrity and switching performance specifications.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV1T34-Q1 family of single power supply buffers. It shares functional characteristics with other LVxT series devices but is distinct in its single-channel configuration and automotive qualification. The DCK package variant offers a compact footprint compared to larger logic IC packages, making it appropriate for dense PCB layouts in modern electronic assemblies.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Non-automotive equivalents such as the standard SN74LV1T34 may be considered if AEC-Q100 qualification is not required. Verify that any substitute maintains the same voltage tolerance and propagation delay characteristics to ensure circuit compatibility.
