Product details
Overview
SN74LV6T07QPWRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive hex open-drain buffer IC with integrated voltage translation, operating from 1.65 V to 5.5 V supply, supporting 5.5-V tolerant inputs and delivering ≤11.5 ns propagation delay at 5 V (CL = 50 pF), used for LED control and inter-module signal translation in vehicle body electronics.
For engineers reviewing the SN74LV6T07QPWRQ1 datasheet, SN74LV6T07QPWRQ1 pinout, SN74LV6T07QPWRQ1 application, or SN74LV6T07QPWRQ1 equivalent, key selection considerations include its open-drain output architecture, LVxT input threshold compatibility with 1.2–5 V logic domains, wettable-flank QFN package option, and automotive-grade ESD robustness (HBM ±2 kV, CDM ±1 kV).
Technical Context
This device implements six independent positive-logic buffers (Y = A) with LVxT-enhanced inputs enabling bidirectional level translation: up-translation (e.g., 1.2 V input → 1.8 V supply → 5 V pull-up) and down-translation (e.g., 5 V input → 1.8 V supply → 0.8 V output). Each channel features a high-impedance output state controlled solely by external pull-up configuration.
The input structure provides reduced VIH/VIL thresholds referenced to VCC (e.g., VIH = 1.1 V min at 1.65–2 V supply), while maintaining 5.5-V absolute input tolerance. Output drive capability is defined by VOL ≤ 0.35 V at IOL = 8 mA (5 V supply), with latch-up immunity exceeding 250 mA per JESD17.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports single-rail operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V - enables direct interfacing with higher-voltage controllers (e.g., 5 V MCU outputs) into lower-supply buffers. |
| Propagation Delay | ≤11.5 ns at 5 V, CL = 50 pF - ensures timing compliance in medium-speed automotive serial control links (e.g., LIN auxiliary signals). |
| Output Drive Strength | VOL ≤ 0.35 V at IOL = 8 mA (5 V supply) - guarantees reliable low-state voltage margin for driving LEDs or wired-AND bus lines. |
| ESD Rating | HBM ±2000 V, CDM ±1000 V - meets AEC-Q100 Grade 1 requirements for under-hood and cabin module reliability. |
| Operating Temperature | −40°C to +125°C - qualified for engine control units, lighting modules, and power distribution systems. |
| Input Leakage Current | ±1 µA max - minimizes loading on weak-drive sources such as microcontroller GPIOs or sensor outputs. |
Pinout & Package
SN74LV6T07QPWRQ1 is available in the PW (TSSOP-14) package: 5 mm × 6.4 mm body, 14-pin surface-mount, with gull-wing leads and standard function pinout compatible with legacy 74-series logic footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A, 5A, 6A | Input | Independent logic inputs for each of six buffer channels; accept 0–5.5 V signals regardless of VCC. |
| 1Y, 2Y, 3Y, 4Y, 5Y, 6Y | Open-Drain Output | Active-low outputs requiring external pull-up; support wired-AND, LED sinking, and multi-master bus configurations. |
| VCC | Power Supply | Single positive supply (1.65–5.5 V); powers internal logic and defines output high-impedance reference. |
| GND | Ground Reference | Return path for all output sink current and supply current; must handle up to ±50 mA total continuous current. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C ambient operation with HBM ±2 kV and CDM ±1 kV ESD robustness - suitable for safety-critical body control modules. |
| LVxT input architecture | Enables seamless up/down translation: e.g., 1.2 V input → 1.8 V supply → 5 V pull-up (up), or 5 V input → 3.3 V supply → 2.5 V output (down). |
| Open-drain output flexibility | Supports wired-AND logic, LED sinking with programmable brightness via pull-up resistor, and multi-source bus arbitration without external diodes. |
| Wettable flank QFN option (BQA) | Enables automated optical inspection (AOI) of solder joints - improves manufacturing yield in automotive PCB assembly. |
| Low quiescent current | ICC ≤ 20 µA max across full temperature range - reduces standby power in always-on vehicle subsystems like door modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07QDRYRQ1 | Single-channel, same AEC-Q100 Grade 1 rating, identical LVxT input and open-drain output specs, but only one buffer per package. | Suitable for point-to-point translation where space or channel count is constrained; requires six devices for full hex functionality. | Select when board area permits discrete channel placement or when partial buffering suffices. |
| MC74VHC1GT07DTT1G | Single-channel, automotive-grade (AEC-Q100), but lacks 5.5-V input tolerance and LVxT enhanced thresholds; VIH min = 1.5 V at 3.3 V supply. | Limited to same-supply or narrow-range translation (e.g., 3.3 V ↔ 5 V only); not suitable for 1.2 V → 3.3 V up-translation. | Choose only for legacy designs already using VHC family; avoid where mixed-voltage domain bridging is required. |
Compared with SN74LV6T07QPWRQ1, SN74LVC1G07QDRYRQ1 offers identical electrical behavior per channel but requires replication for multi-signal use, whereas MC74VHC1GT07DTT1G lacks the wide-input-tolerance and low-threshold features essential for flexible automotive voltage translation.

FAQ
What is the maximum input voltage the SN74LV6T07QPWRQ1 can tolerate?
The SN74LV6T07QPWRQ1 supports input voltages up to 5.5 V regardless of supply voltage - a key feature enabling down-translation from higher-voltage domains (e.g., 5 V MCU outputs) into lower-supply logic. This rating is specified in the Absolute Maximum Ratings table and validated per AEC-Q100 stress testing protocols.
Does the SN74LV6T07QPWRQ1 require external pull-up resistors on its outputs?
Yes, the SN74LV6T07QPWRQ1 has open-drain outputs and cannot drive a logic HIGH state internally. An external pull-up resistor is mandatory to establish a defined HIGH voltage level; typical values range from 1 kΩ (for speed-critical 6.67 Mbps operation) to 10 kΩ (for low-power LED control), depending on load capacitance and current requirements.
Can the SN74LV6T07QPWRQ1 perform bidirectional level translation?
No, the SN74LV6T07QPWRQ1 performs unidirectional translation only: input → output. Its LVxT inputs accept wide-voltage signals (0–5.5 V), while outputs reflect the input state in open-drain form - enabling up-translation (low-Vin → high-Vpullup) or down-translation (high-Vin → low-Vcc), but not automatic bidirectional data flow like I²C bus buffers.
What is the thermal performance difference between the PW (TSSOP) and BQA (WQFN) packages of the SN74LV6T07QPWRQ1?
The BQA (WQFN-14) package has RθJA = 88.3°C/W, significantly better than the PW (TSSOP-14) at 151.0°C/W. This 41% lower junction-to-ambient resistance makes BQA preferable for thermally constrained automotive applications, especially when multiple channels operate continuously under load.
Is the SN74LV6T07QPWRQ1 pin-compatible with standard 74-series hex buffers like SN74LS07?
No - while SN74LV6T07QPWRQ1 uses the same 14-pin TSSOP (PW) footprint as legacy 74LS07, its pinout differs: SN74LV6T07QPWRQ1 follows a functional layout (1A/1Y, 2A/2Y, ..., VCC/GND), whereas SN74LS07 uses interleaved inputs/outputs. Direct replacement requires PCB redesign or adapter routing.
