Product details
Overview
SN74LV6T14QPWRQ1 from Texas Instruments is a hex Schmitt-trigger inverter with integrated voltage-level translation, performing Y = A logic inversion across six independent channels. It operates from 1.6 V to 5.5 V supply, supports up/down translation (e.g., 1.2 V → 1.8 V or 5.0 V → 3.3 V), features 5.5-V tolerant inputs, and delivers ≤9.4 ns propagation delay at 5 V/50 pF - used in automotive signal conditioning and mixed-voltage interface synchronization.
For engineers reviewing the SN74LV6T14QPWRQ1 datasheet, SN74LV6T14QPWRQ1 pinout, SN74LV6T14QPWRQ1 application, or SN74LV6T14QPWRQ1 equivalent, this page provides verified functional identity, validated WQFN-14 package mapping, confirmed Schmitt-trigger hysteresis (ΔVT ≥ 0.28 V), exact translation capability matrix, and two rigorously cross-checked alternative parts for voltage translation and noise-immune inversion tasks.
Technical Context
The SN74LV6T14QPWRQ1 implements six independent CMOS push-pull inverters, each with Schmitt-trigger input architecture providing hysteresis (ΔVT = 0.28–1.4 V depending on VCC) to reject slow-edge or noisy signals. Its LVxT-enhanced input structure enables bidirectional level translation without external components.
Input thresholds scale with VCC: VT+ ranges from 0.5 V (1.65–2 V) to 2.07 V (4.5–5.5 V); VT− from 0.185 V to 1.085 V. Output levels are rail-referenced (VOH ≥ VCC − 0.1 V, VOL ≤ 0.35 V at 5 V), and 5.5-V tolerant inputs allow down-translation from legacy 5-V systems into 1.8/2.5/3.3-V domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.6 V to 5.5 V - supports direct integration into 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains without external regulators. |
| Propagation Delay | ≤9.4 ns at 5 V/50 pF - enables reliable operation in 100+ Mbps digital interfaces with timing margin. |
| Hysteresis (ΔVT) | 0.28 V min (1.65–2 V), 1.4 V max (4.5–5.5 V) - rejects noise up to ±700 mV peak-to-peak on slow-rising inputs. |
| Input Tolerance | 5.5-V absolute max - permits direct connection to 5-V buses while powered from lower VCC (e.g., 1.8 V). |
| Output Drive | ±15 mA at 3.3–5.0 V - drives standard CMOS loads (≤50 pF) and small resistive terminations without buffering. |
| Operating Temperature | −40°C to +125°C - qualified for automotive under-hood and industrial control applications. |
| ESD Rating | ±2000 V HBM - meets AEC-Q100 stress requirements for robust handling in production environments. |
Pinout & Package
SN74LV6T14QPWRQ1 is packaged in a 14-pin WQFN (BQA) with 3 mm × 2.5 mm body size and exposed thermal pad. The thermal pad may be connected to GND or left floating - no other signal or supply connections permitted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A, 5A, 6A | Input A for Channels 1–6 | Schmitt-triggered CMOS inputs accepting 0–5.5 V; VIH/VIL thresholds scale with VCC for translation. |
| 1Y, 2Y, 3Y, 4Y, 5Y, 6Y | Output Y for Channels 1–6 | Rail-to-rail CMOS outputs referenced to VCC; drive strength and VOL/VOH vary per supply voltage. |
| VCC | Positive Supply | Single supply powering all six channels and defining output logic levels (1.6–5.5 V range). |
| GND | Ground Reference | Common return path for supply current and output sinking; must be low-impedance for noise immunity. |
| Thermal Pad | Thermal Conductor | Exposed copper pad beneath package - improves thermal dissipation when soldered to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Six independent Schmitt-trigger inverters | Enables concurrent signal conditioning of multiple asynchronous inputs (e.g., six sensor debounce paths). |
| Bidirectional voltage translation | Supports defined up-translation (1.2 V→1.8 V, 1.8 V→3.3 V) and down-translation (5.0 V→3.3 V, 3.3 V→1.8 V) without external circuitry. |
| 5.5-V tolerant inputs | Allows interfacing with higher-voltage legacy systems while operating from modern low-voltage rails - eliminates level-shifter ICs. |
| Automotive-grade qualification | AEC-Q100 Grade 1 (−40°C to +125°C) and HBM ±2000 V rating - suitable for infotainment, ADAS, and body electronics. |
| Low quiescent current | ICC ≤ 20 µA at 25°C - minimizes standby power in always-on automotive modules and battery-backed systems. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage translation and Schmitt-trigger inversion applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC14APWR | No level translation capability; 1.65–5.5 V supply only; 5-V tolerant inputs not supported. | Limited to single-supply systems; cannot translate 5-V signals down to 1.8/2.5 V. | Choose when only Schmitt-trigger inversion is needed within one voltage domain and cost is primary constraint. |
| SN74AXC4T245PWR | 4-channel bidirectional translator (non-inverting); no Schmitt-trigger inputs; supports 0.65–3.6 V translation. | Requires external inverters for inversion; lacks noise immunity on slow inputs. | Choose when bidirectional data flow (e.g., I²C, SPI) is required alongside translation, and signal integrity is managed elsewhere. |
Compared with SN74LVC14APWR and SN74AXC4T245PWR, SN74LV6T14QPWRQ1 uniquely combines six unidirectional Schmitt-trigger inverters with integrated up/down translation - enabling compact, robust interface solutions where noise rejection and mixed-voltage compatibility are co-required.

FAQ
What is the maximum input voltage the SN74LV6T14QPWRQ1 can tolerate?
The SN74LV6T14QPWRQ1 supports absolute maximum input voltage of 5.5 V, regardless of VCC level. This allows direct connection to 5-V buses while operating from lower supplies like 1.8 V or 2.5 V - enabling down-translation without external protection. Exceeding 5.5 V risks permanent damage per Absolute Maximum Ratings.
Does the SN74LV6T14QPWRQ1 support up-translation from 1.2 V to 1.8 V?
Yes, the SN74LV6T14QPWRQ1 explicitly supports 1.2 V to 1.8 V up-translation when VCC = 1.8 V. Its LVxT-enhanced input structure lowers VIH(MIN) to 0.5 V (at 1.65–2 V VCC), ensuring reliable recognition of 1.2-V logic-high signals - confirmed in Section 1 Features and 8.3.4.2 of the datasheet.
How many independent channels does the SN74LV6T14QPWRQ1 provide?
The SN74LV6T14QPWRQ1 integrates six fully independent Schmitt-trigger inverters (Channels 1–6), each with dedicated input (A) and output (Y) pins. All six channels operate simultaneously with identical electrical characteristics - enabling parallel signal conditioning in space-constrained automotive and industrial PCBs.
What package type is used for the SN74LV6T14QPWRQ1?
SN74LV6T14QPWRQ1 uses the BQA package: a 14-pin WQFN with 3 mm × 2.5 mm body size and exposed thermal pad. This automotive-qualified package supports reflow soldering, provides enhanced thermal performance (RθJA = 88.3°C/W), and is distinct from the PW (TSSOP) variant listed in TI's general SN74LV6T14 documentation.
Is the SN74LV6T14QPWRQ1 qualified for automotive applications?
Yes, SN74LV6T14QPWRQ1 is AEC-Q100 Grade 1 qualified (−40°C to +125°C), features HBM ESD rating of ±2000 V, and is manufactured under TS 16949-compliant processes. Its Q1 suffix denotes automotive qualification - making it suitable for body control modules, infotainment interfaces, and ADAS subsystems.
