Product details

Overview

SN74LV6T17QWBQARQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive hex Schmitt-trigger buffer with integrated voltage translation, operating from 1.6 V to 5.5 V supply, supporting up/down level translation (e.g., 1.2 V → 1.8 V, 3.3 V → 2.5 V), delivering ≤7.7 ns propagation delay at 5 V/50 pF, and featuring 5.5-V tolerant inputs for robust interface bridging in body control modules.

For engineers reviewing the SN74LV6T17QWBQARQ1 datasheet, SN74LV6T17QWBQARQ1 pinout, SN74LV6T17QWBQARQ1 application, or SN74LV6T17QWBQARQ1 equivalent, this page delivers verified electrical parameters, validated translation capability per supply rail, confirmed QFN-14 wettable flank package mapping, and real-world automotive use context - all extracted directly from TI's SCLS933 production datasheet.

Technical Context

The SN74LV6T17QWBQARQ1 implements six independent Schmitt-trigger buffers (Y = A) with hysteresis ΔVT ranging from 0.28 V to 1.4 V depending on VCC, enabling noise immunity against slow or noisy signals. Its LVxT architecture provides asymmetric input thresholds (VIH as low as 0.5 V at 1.8 V VCC; VIL as high as 0.85 V at 5.5 V VCC) to support bidirectional voltage translation without external components.

Each channel features balanced CMOS push-pull outputs capable of ±15 mA at 3.3–5.0 V VCC, with output voltage referenced strictly to VCC (VOH ≥ VCC − 0.1 V, VOL ≤ 0.35 V). Input pins tolerate up to 5.5 V regardless of VCC, allowing safe down-translation from legacy 5-V domains into modern 1.8/2.5/3.3-V microcontrollers.

Pinout & Package

SN74LV6T17QWBQARQ1 is packaged in a 14-pin wettable flank WQFN (BQA), 3 mm × 2.5 mm body size, with exposed thermal pad (connected to GND or left floating). The package supports automated optical inspection (AOI) via side-fillet formation and enables efficient thermal dissipation (R_θJA = 88.3°C/W).

Pin/Terminal	Circuit Role	Design Meaning
1A–6A	Input A of Channels 1–6	High-impedance Schmitt-trigger inputs accepting 0–5.5 V; VIH/VIL thresholds scale with VCC for translation.
1Y–6Y	Output Y of Channels 1–6	CMOS push-pull outputs referenced to VCC; VOH/VOL defined per supply rail and load current.
VCC	Positive Supply	Single power rail setting output logic levels and input threshold voltages; no separate I/O supply required.
GND	Ground Reference	Common return path for all channels; thermal pad may be tied to GND for improved heat transfer.
Thermal Pad	Thermal Interface	Exposed copper pad beneath package body; improves thermal resistance (R_θJB = 56.8°C/W) when soldered to PCB ground plane.

Key Features

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex Schmitt-trigger buffer with translation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC14AQPWRQ1	No voltage translation; fixed 1.65–3.6 V operation; VIH/VIL tied to VCC only; no 5.5-V tolerant inputs.	Suitable only for same-voltage domain buffering; cannot replace SN74LV6T17QWBQARQ1 in mixed-rail interfaces.	Select when translation is unnecessary and cost optimization is prioritized over interface flexibility.
SN74AXC4T245PWR	Direction-controlled 4-channel translator; no Schmitt inputs; higher channel count but no hysteresis; supports 0.65–3.6 V dual supplies.	Requires external direction control and pull-ups; unsuitable for noise-prone analog switch inputs or open-drain emulation.	Choose only for high-speed bidirectional data buses (e.g., I²C, SPI) where Schmitt noise rejection is not required.

Compared with SN74LVC14AQPWRQ1 and SN74AXC4T245PWR, SN74LV6T17QWBQARQ1 uniquely combines Schmitt-trigger noise immunity, single-supply translation, and 5.5-V input tolerance - making it irreplaceable in automotive signal conditioning where voltage domain bridging and EMI resilience are co-required.

FAQ

What is the maximum input voltage the SN74LV6T17QWBQARQ1 can accept?

The SN74LV6T17QWBQARQ1 accepts input voltages up to 5.5 V regardless of VCC level, as specified in its Absolute Maximum Ratings. This allows safe down-translation from 5-V sources even when powered from 1.8 V, eliminating risk of damage during mixed-voltage interface operation. Inputs must remain within −0.5 V to 5.5 V to avoid permanent device degradation.

Does the SN74LV6T17QWBQARQ1 require external pull-up or pull-down resistors on unused inputs?

Yes - unused inputs on the SN74LV6T17QWBQARQ1 must be terminated to either VCC or GND to prevent floating states that cause excessive current draw and potential oscillation. A 10-kΩ resistor is recommended for pull-up/pull-down configurations, especially in systems where inputs may be inactive during certain operational modes.

Can the SN74LV6T17QWBQARQ1 translate 1.2-V signals to 3.3-V outputs?

No - the SN74LV6T17QWBQARQ1 supports only specific up-translation combinations per its datasheet: 1.2 V → 1.8 V, 1.5 V → 2.5 V, 1.8 V → 3.3 V, and 3.3 V → 5.0 V. For 1.2 V → 3.3 V translation, two-stage cascading (e.g., 1.2 V → 1.8 V → 3.3 V) or alternate devices like SN74AXC series would be required.

What is the thermal performance of the SN74LV6T17QWBQARQ1 in its WQFN package?

The SN74LV6T17QWBQARQ1 in the BQA (WQFN-14) package has a junction-to-ambient thermal resistance (R_θJA) of 88.3°C/W and junction-to-board (R_θJB) of 56.8°C/W. With proper PCB copper pour under the thermal pad, it sustains continuous operation at 125°C ambient when dissipating ≤150 mW - typical for six-channel operation at 3.3 V/5 mA per output.

Is the SN74LV6T17QWBQARQ1 pin-compatible with standard 74LV series hex buffers?

No - the SN74LV6T17QWBQARQ1 uses a non-standard 14-pin WQFN (BQA) footprint with dedicated 1A/1Y through 6A/6Y pins and no enable or direction control lines. It is not pin-compatible with legacy 74LV14 or 74LV16 buffers in TSSOP or SOIC packages; board redesign is required for migration.
