SN74LV1T125QDCKRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV1T125-Q1 is an automotive-grade single buffer gate with 3-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 to 1.8 V) and down-translation from higher voltage inputs (e.g., 5.0 V to 3.3 V). It features 5.5-V tolerant input pins, balanced CMOS outputs, and latch-up performance exceeding 250 mA per JESD 17. Available in SC-70 (DCK) and SOT-23 (DBV) packages.

• Integrated voltage level translation supporting both up-translation and down-translation
• Balanced CMOS 3-state outputs controlled by an active-low OE pin
• 5.5-V tolerant input pins allowing operation across various logic levels

Buffers, Drivers, Receivers, Transceivers Applications

• Translation between communication modules and system controllers
• Enabling or disabling digital signals via the output enable pin
• Controlling indicator LEDs

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant required, as the SN74LV1T125-Q1 is available in DCK (SC-70) and DBV (SOT-23) configurations. Confirm that the application environment meets the AEC-Q100 qualification requirements for automotive use. Ensure supply voltages remain within the 1.6 V to 5.5 V range during operation. Check datasheet specifications for thermal resistance values if operating near maximum temperature limits.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with bidirectional voltage translation capabilities is needed in space-constrained designs. It is suitable for interfacing between systems operating at different voltage levels, such as 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V. Consider the SC-70 or SOT-23 package options based on board space availability. Ensure input signal transition rates comply with recommended operating conditions to prevent oscillations.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to Texas Instruments' LVxT family of logic devices, which are designed with enhanced input voltage thresholds to facilitate seamless voltage level shifting. The 'Q1' suffix indicates automotive qualification under AEC-Q100 standards. It serves as a bridge between low-voltage microcontrollers and higher-voltage peripherals or communication buses.
