Product details
Overview
SN74LV6T07 from Texas Instruments is a hex open-drain buffer IC designed for voltage-level translation in mixed-voltage digital systems. It features six independent channels, 1.65 V to 5.5 V supply range, 5.5-V tolerant inputs, and supports up-translation (e.g., 1.2 V → 1.8 V) and down-translation (e.g., 5 V → 0.8 V). It is used in signal enable/disable, LED control, and inter-module communication interfaces.
For engineers reviewing the SN74LV6T07 datasheet, SN74LV6T07 pinout, SN74LV6T07 application, or SN74LV6T07 equivalent, key selection considerations include open-drain output drive capability, input voltage threshold compatibility across 1.2–5.5 V logic domains, thermal performance in WQFN/TSSOP packages, and latch-up immunity per JESD17.
Technical Context
The SN74LV6T07 implements six identical positive-logic buffers (Y = A) with LVxT-enhanced inputs-lower VIH/VIL thresholds enabling reliable up-translation, and 5.5-V tolerance enabling robust down-translation. Each channel operates independently with open-drain outputs requiring external pull-up resistors.
Its architecture supports bidirectional voltage translation without direction control pins: input logic levels are referenced to VCC, while output high state is determined solely by the external pull-up network. Switching performance is characterized at CL = 15 pF and CL = 50 pF across 1.8 V–5 V supplies, with tPLZ/tPZL as low as 4.3 ns (5 V, 15 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Input Voltage Tolerance | Up to 5.5 V - allows direct connection of 5-V signals into lower-supply devices without level-shifting circuitry |
| Output Type | Open-drain - requires external pull-up for HIGH state; supports wired-AND, I²C-like bus sharing, and LED sinking |
| Max Output Sink Current | 25 mA per channel - sufficient to directly drive indicator LEDs or interface with standard CMOS inputs |
| Propagation Delay | 4.3 ns (min, 5 V, CL = 15 pF) - supports >6.67-Mbps data rates with 1-kΩ pull-up and 30-pF load |

Pinout & Package
SN74LV6T07 is available in two RoHS-compliant packages: 14-pin WQFN (BQA, 3 mm × 2.5 mm body) and 14-pin TSSOP (PW, 5 mm × 4.4 mm body). Both packages support thermal pad (BQA only) connected to GND or left floating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A–6A | Input | Six independent logic inputs; each accepts 0–5.5 V signals regardless of VCC |
| 1Y–6Y | Open-drain output | Six independent outputs; sink current only; require external pull-up for HIGH |
| VCC | Power supply | Single supply pin defining logic thresholds and output LOW voltage limits |
| GND | Ground reference | Return path for all output sink current and supply current; must handle total IOUT + ICC |
| Thermal Pad (BQA) | Thermal & electrical plane | Improves thermal dissipation; may be connected to GND for EMI reduction or left floating |
Key Features
| Feature | Design Value |
|---|---|
| Integrated voltage translation | Eliminates discrete level-shifters: supports 1.2 V → 1.8 V up-translation and 5 V → 0.8 V down-translation using single VCC |
| 5.5-V tolerant inputs | Enables direct interfacing of legacy 5-V peripherals to modern low-voltage controllers without external protection |
| Open-drain flexibility | Permits wired-AND bus topologies, shared interrupt lines, and programmable LED current via pull-up resistor selection |
| Wide temperature range | –40°C to +125°C operation ensures reliability in automotive under-hood, industrial PLC, and outdoor IoT deployments |
| Low static current | ICC ≤ 20 µA max - minimizes quiescent power in battery-backed or always-on subsystems |
Applications
| LED Indicator Control | Inter-Module Signal Translation |
|---|---|
Use Scenario: Driving status LEDs from ultra-low-voltage microcontrollers (e.g., 1.2-V or 1.8-V MCUs) while powering LEDs from higher rails (e.g., 3.3 V or 5 V). IC Role / Device Role / Timing Role: SN74LV6T07 acts as a voltage-translating current sink, accepting low-voltage logic inputs and sinking current from externally pulled-up LED anodes. Use Value: Enables direct MCU-to-LED control without additional MOSFET drivers or dedicated level shifters, reducing BOM count and PCB area. | Use Scenario: Connecting 3.3-V UART peripherals to a 5-V system controller where signal integrity and voltage compatibility are critical. IC Role / Device Role / Timing Role: SN74LV6T07 serves as a unidirectional level translator on TX/RX lines, translating 3.3-V logic outputs to 5-V compatible levels using external 5-V pull-ups. Use Value: Maintains timing compliance (tPLZ/tPZL ≤ 7.7 ns @ 3.3 V, 50 pF) while eliminating risk of overvoltage damage to 3.3-V transceivers. |
| Enable/Disable Digital Signals | Wired-AND Bus Interface |
Use Scenario: Enabling/disabling clock or reset signals between subsystems operating at different supply voltages (e.g., 1.8-V sensor hub and 2.5-V processor). IC Role / Device Role / Timing Role: SN74LV6T07 functions as a voltage-agnostic gate: input controls output state; open-drain output pulls signal line LOW when enabled, floats when disabled. Use Value: Provides clean, glitch-free enable control across voltage domains without timing skew introduced by multi-stage translators. | Use Scenario: Implementing shared interrupt or acknowledge lines across multiple 1.8-V and 3.3-V devices on a common bus. IC Role / Device Role / Timing Role: SN74LV6T07 channels operate in parallel with outputs tied together; any device pulling LOW asserts the bus, matching wired-AND logic behavior. Use Value: Supports mixed-voltage bus arbitration with no additional logic gates or voltage translators-only one shared pull-up required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain translation buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC6T245 | Bi-directional, 3-state, dual-supply (VCCA/VCCB), higher drive (32 mA), no open-drain | Requires direction control and separate supplies; suited for bidirectional data buses, not simple enable/LED sink | Select when bidirectional translation or higher drive is needed; avoid if open-drain or single-supply simplicity is required |
| TXS0106E | Auto-direction-sensing, 6-channel, push-pull outputs, 1.65–5.5 V dual-supply, no open-drain | Designed for I²C/SPI with automatic direction detection; lacks true open-drain behavior and wired-AND capability | Prefer for protocol-aware translation; not suitable for wired-AND or LED sinking where true high-Z is mandatory |
Compared with SN74LVC6T245 and TXS0106E, the SN74LV6T07 uniquely combines single-supply operation, true open-drain outputs, and integrated LVxT translation-making it optimal for enable gating, LED control, and wired-AND bus design where direction control or dual supplies add complexity.

FAQ
What is the maximum input voltage the SN74LV6T07 can tolerate?
The SN74LV6T07 supports input voltages up to 5.5 V regardless of VCC setting-enabling safe interfacing of 5-V signals into 1.8-V or 2.5-V systems. This tolerance is specified in the Absolute Maximum Ratings table and verified per JEDEC standards. Exceeding 5.5 V risks permanent damage, even with current limiting.
Can the SN74LV6T07 drive an LED directly?
Yes, the SN74LV6T07 can directly sink LED current: each channel supports up to 25 mA sink current, and VOL remains ≤0.35 V at 8 mA with 5-V supply. To drive an LED, connect the anode to a higher voltage rail (e.g., 3.3 V or 5 V) via a current-limiting resistor, and the cathode to an SN74LV6T07 output pin. The SN74LV6T07 then pulls the cathode LOW to illuminate the LED.
Does the SN74LV6T07 require external pull-up resistors?
Yes, every SN74LV6T07 output requires an external pull-up resistor to establish a defined HIGH logic level. Because outputs are open-drain, they cannot source current. Typical values range from 1 kΩ (for speed-critical <6.67 Mbps links) to 10 kΩ (for low-power LED indicators); selection depends on load capacitance, speed requirements, and power budget.
What is the minimum supply voltage for reliable operation of the SN74LV6T07?
The SN74LV6T07 operates reliably down to 1.65 V, as specified in the Recommended Operating Conditions. At 1.65 V, VIH is guaranteed ≥1.1 V and VIL ≤0.5 V, supporting clean interfacing with 1.2-V or 1.8-V logic sources. Performance metrics-including propagation delay and VOL-are fully characterized across this full 1.65–5.5 V range.
How does the SN74LV6T07 handle unused inputs and outputs?
Unused inputs on the SN74LV6T07 must be terminated to a valid logic level-either VCC or GND-using a 10-kΩ resistor or direct connection; floating inputs cause undefined states and increased power consumption. Unused outputs may be left unconnected (floating), as open-drain outputs in high-impedance state draw only ±0.25 µA leakage current per the Electrical Characteristics table.
