Product details
Overview
SN74LV6T17 from Texas Instruments is a hex Schmitt-trigger buffer with integrated voltage-level translation, performing Y = A logic in positive logic 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 3.3 V → 2.5 V), features 5.5-V tolerant inputs, and delivers ≤7.7 ns propagation delay at 5 V with 50-pF load - used for signal conditioning between mixed-voltage communication modules and system controllers.
For engineers reviewing the SN74LV6T17 datasheet, SN74LV6T17 pinout, SN74LV6T17 application, or SN74LV6T17 equivalent, key selection considerations include its dual-role as level translator and noise-immune buffer, guaranteed hysteresis (ΔVT ≥ 0.28 V), 150 Mbps data rate capability, thermal performance in WQFN/TSSOP packages, and compatibility with 1.2–5.5 V input domains without external biasing.
Technical Context
The SN74LV6T17 implements six independent CMOS push-pull buffers, each with Schmitt-trigger inputs providing hysteresis (ΔVT = 0.28–1.4 V depending on VCC) to reject slow-rising or noisy signals. Its LVxT architecture enables bidirectional voltage translation: reduced VIH/VIL thresholds support up-translation (e.g., 1.8 V input → 3.3 V output), while 5.5-V tolerant inputs enable down-translation (e.g., 5 V input → 2.5 V output).
Output levels are strictly referenced to VCC (1.8/2.5/3.3/5 V), with VOH ≥ VCC − 0.1 V and VOL ≤ 0.35 V under full drive, and switching performance validated from −40°C to 125°C. The device requires no external components for translation, supports standard TSSOP-14 and WQFN-14 footprints, and includes wettable flanks in BQA package for AOI-compatible solder joint inspection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.6 V to 5.5 V - enables single-supply operation across 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains without auxiliary rails. |
| Input Voltage Tolerance | Up to 5.5 V - allows direct connection of higher-voltage signals (e.g., 5 V MCU GPIO) into lower-VCC systems (e.g., 1.8 V FPGA I/O) without clamping diodes or resistors. |
| Hysteresis (ΔVT) | Min 0.28 V at 1.8 V VCC - ensures robust noise immunity against >200 mV peak-to-peak interference on slow or unterminated lines. |
| Propagation Delay (tPD) | ≤7.7 ns at 5 V / 50 pF - supports clean 150 Mbps digital signaling in high-speed interconnects like sensor buses or display control links. |
| Output Drive | ±15 mA at 3.3–5 V VCC - sufficient to drive 50-pF loads directly, including multiple gate inputs or short PCB traces without series termination. |
| Operating Temperature | −40°C to +125°C - qualified for automotive under-hood, industrial motor control, and outdoor embedded applications. |
| ESD Rating | ±2000 V HBM - meets JEDEC JS-001 for safe handling in automated assembly and field-replaceable module integration. |
Pinout & Package
SN74LV6T17 is available in two RoHS-compliant packages: PW (14-pin TSSOP, 5 mm × 6.4 mm body) and BQA (14-pin WQFN, 3 mm × 2.5 mm body with wettable flanks). Both packages support standard PCB assembly and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A–6A | Input (Schmitt-trigger) | Six independent logic inputs accepting 0–5.5 V; threshold hysteresis rejects noise and accommodates slow edges. |
| 1Y–6Y | Output (CMOS push-pull) | Six buffered outputs referenced to VCC; drive strength scales with supply (±3 mA @ 1.8 V, ±15 mA @ 3.3 V). |
| VCC | Positive supply | Single power rail setting output logic levels and input thresholds; must be stable within ±5 % for spec compliance. |
| GND | Ground reference | Common return path for all I/O and supply currents; low-inductance connection required for noise control. |
| Thermal Pad (BQA only) | Thermal and mechanical anchor | Exposed pad improves thermal dissipation (RθJB = 56.8°C/W); may be connected to GND plane or left floating per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs with programmable hysteresis | ΔVT adjustable via VCC (0.28–1.4 V range) - eliminates need for external RC filters in noisy industrial sensor interfaces. |
| Integrated bidirectional level translation | No external components needed for 1.2 V ↔ 1.8 V, 1.8 V ↔ 3.3 V, 3.3 V ↔ 5.0 V translation - reduces BOM count and layout area. |
| 5.5-V tolerant inputs on all channels | Accepts overvoltage inputs up to 5.5 V regardless of VCC - enables direct interfacing with legacy 5-V peripherals in modern low-voltage systems. |
| Wettable flanks (BQA package) | Enhanced side-fillet formation for automated optical inspection - improves manufacturing yield in high-reliability automotive and medical assemblies. |
| High-speed performance | 150 Mbps data rate supported at 5 V with 50-pF load - suitable for SPI, I²C clock extension, and GPIO expansion in real-time control systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer with level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Single-channel Schmitt buffer, no level translation; 1.65–5.5 V VCC but input not 5.5-V tolerant. | Limited to same-supply-domain buffering; cannot translate 5 V → 1.8 V or 1.2 V → 1.8 V. | Choose only if translation is unnecessary and channel count allows cascading six units - increases board area and power vs. SN74LV6T17's integrated solution. |
| TXS0106EPRJR | 6-channel auto-directional translator; push-pull outputs but no Schmitt inputs; supports 1.2–3.6 V I/O domains. | Requires direction control or relies on bus activity; lacks hysteresis for noisy environments; not rated for 125°C operation. | Select when bidirectional data flow (e.g., I²C) is required, but avoid where input noise immunity or extended temperature range is critical. |
Compared with SN74LVC1G17DBVR and TXS0106EPRJR, the SN74LV6T17 uniquely combines six-channel Schmitt buffering, 5.5-V tolerant inputs, and true up/down translation in one package - delivering deterministic timing, noise resilience, and mixed-voltage interoperability without external components or thermal derating compromises.

FAQ
What voltage levels can SN74LV6T17 translate between?
The SN74LV6T17 supports verified up-translation (e.g., 1.2 V → 1.8 V, 1.8 V → 3.3 V, 2.5 V → 5.0 V) and down-translation (e.g., 5.0 V → 3.3 V, 3.3 V → 2.5 V, 5.0 V → 1.8 V) based on VCC selection and input thresholds defined in the Recommended Operating Conditions table. Translation is unidirectional per channel and requires no external circuitry.
Does SN74LV6T17 require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs on SN74LV6T17 must be terminated to VCC or GND to prevent floating states that cause excessive current draw and potential oscillation. A 10-kΩ resistor is recommended per TI application guidance; direct connection is acceptable if the input remains static in the final design.
What is the maximum capacitive load SN74LV6T17 can drive while maintaining datasheet timing specs?
The SN74LV6T17 is characterized and guaranteed to meet all switching specifications (e.g., tPD ≤ 7.7 ns) with a 50-pF load at 5 V VCC. Driving larger capacitances is possible but degrades propagation delay and increases dynamic power; TI recommends limiting total load to ≤50 pF for full spec compliance.
How does the Schmitt-trigger input hysteresis of SN74LV6T17 improve system reliability?
The SN74LV6T17 provides minimum hysteresis (ΔVT) of 0.28 V at 1.8 V VCC, increasing to 1.4 V at 5.5 V VCC. This built-in voltage margin prevents multiple output transitions caused by slow edges or noise spikes - critical for reliable operation in industrial sensor lines, automotive harnesses, and medical equipment with long cables or EMI exposure.
Is SN74LV6T17 qualified for automotive applications?
SN74LV6T17 is specified for operation from −40°C to +125°C and meets JEDEC JESD17 latch-up performance (>250 mA), but it is not AEC-Q100 qualified. For automotive use, TI recommends verifying system-level qualification per ISO/TS 16949; the device is widely deployed in body control modules where full AEC-Q100 is not mandated.
