Product details
Overview
SN74LVC07ADR from Texas Instruments is a hex buffer and driver IC with six independent open-drain outputs, designed for 1.65 V to 5.5 V operation, supporting 24 mA sink current per output at 3.3 V, 5.6 ns max propagation delay at 1.8 V, and 5.5 V-tolerant inputs/outputs - used in level translation and wired-OR logic interfaces in consumer audio and SSD power control.
For engineers reviewing the SN74LVC07ADR datasheet, SN74LVC07ADR pinout, SN74LVC07ADR application, or SN74LVC07ADR equivalent, key selection considerations include open-drain drive strength, Ioff-enabled partial-power-down capability, 1.65–5.5 V supply flexibility, 5.5 V input tolerance, and SOIC-14 package compatibility with legacy board layouts.
Technical Context
The SN74LVC07ADR implements six identical CMOS buffer stages, each with an open-drain output stage capable of sinking up to 24 mA at VCC = 3 V and 5.5 V-tolerant inputs that operate independently of VCC level. Its Ioff circuitry actively disables all outputs when VCC = 0 V, preventing back-drive current during hot-insertion or partial-power-down scenarios.
This device supports bidirectional voltage translation: inputs accept 1.8 V, 2.5 V, 3.3 V, or 5 V logic levels regardless of VCC (1.65–5.5 V), while outputs interface directly with external pull-up networks at voltages up to 5.5 V - enabling use in mixed-supply systems without additional level-shifting components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct integration into 1.8 V, 2.5 V, 3.3 V, and 5 V domains without external regulators |
| Max Sink Current per Output | 24 mA at VCC = 3 V - sufficient to drive multiple CMOS inputs or small LEDs without external transistors |
| Propagation Delay (tpd) | 2.6 ns at VCC = 5 V - supports signal integrity in high-speed digital interfaces up to ~100 MHz |
| Input/Output Voltage Tolerance | Up to 5.5 V - allows interfacing with 5 V logic while powered from lower VCC, eliminating need for discrete level shifters |
| Ioff Current | ±10 µA at VCC = 0 V - ensures safe live insertion and prevents back-current flow during system power sequencing |
| Operating Temperature | –40°C to +125°C - qualified for industrial and extended-temperature embedded applications |

Pinout & Package
SN74LVC07ADR is packaged in a 14-pin SOIC (D) with 8.65 mm × 3.91 mm body size, surface-mount footprint, and standard 1.27 mm pitch - compatible with IPC-7351B SOIC-14 land pattern and reflow soldering profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 3A, 5A, 2A, 4A, 6A | Input | Six independent CMOS-compatible digital inputs; tolerate up to 5.5 V regardless of VCC |
| 1Y, 2Y, 3Y, 4Y, 5Y, 6Y | Open-Drain Output | Six active-low outputs requiring external pull-up; each sinks up to 24 mA at 3 V |
| VCC | Power Supply | Single supply pin for 1.65–5.5 V operation; powers internal logic and defines output high-level reference |
| GND | Ground Reference | Common return path for all inputs, outputs, and internal circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5 V) | Enables single part to serve multiple rail domains - reduces BOM count in multi-voltage systems |
| 5.5 V-tolerant I/O | Permits direct connection to 5 V buses while operating from 1.8 V or 3.3 V supplies - eliminates discrete translators |
| Ioff partial-power-down | Prevents current backflow when VCC is off - critical for hot-swap, PCIe add-in cards, and modular power systems |
| 24 mA sink per output | Drives 10+ standard CMOS loads or small indicator LEDs without buffering - simplifies peripheral interface design |
| 2.6 ns tpd at 5 V | Meets timing budgets in high-speed control paths such as SSD enable sequencing and display backlight PWM |
Applications
| SSD Power Sequencing | USB-C Port Controller Interface |
|---|---|
Use Scenario: Controlling 5 V auxiliary rails and reset signals during client SSD power-up and shutdown sequences. IC Role / Device Role / Timing Role: Hex open-drain buffer providing isolated, high-current enable/disable control for PMICs and LDOs. Use Value: 24 mA sink per channel drives multiple power-good inputs simultaneously; Ioff prevents backfeed during staggered power ramp. |

Use Scenario: Driving LED backlight strings in panel-mounted HMIs where microcontroller GPIOs lack sufficient current. IC Role / Device Role / Timing Role: High-drive buffer translating MCU PWM signals to 5 V LED driver enable inputs. Use Value: 24 mA sink supports direct drive of optocoupler inputs or MOSFET gate drivers; 125°C rating suits enclosed enclosures. |
Use Scenario: Implementing wired-AND arbitration on shared I²C or SMBus lines across multiple masters. IC Role / Device Role / Timing Role: Open-drain logic gate enabling collision detection and bus contention resolution. Use Value: Six independent channels support multi-node arbitration; 5.5 V tolerance accommodates mixed-voltage bus topologies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC06ADR | Inverting logic function (buffer outputs inverted); same VCC range, I/O tolerance, and drive strength | Requires logic inversion in signal path - unsuitable where non-inverting polarity is mandatory | Select SN74LVC06ADR only when system-level logic requires active-low outputs by default |
| 74AHC1G07SE-7 | Single-channel open-drain buffer in SOT-23-5; 8 mA sink at 5 V; no Ioff; 2.0–5.5 V supply only | Limited to one channel per package; lacks partial-power-down protection and higher drive capability | Use 74AHC1G07SE-7 for space-constrained single-signal translation where Ioff and >12 mA drive are not required |
Compared with SN74LVC06ADR, SN74LVC07ADR provides non-inverting functionality essential for direct enable/control paths; compared with 74AHC1G07SE-7, it delivers six channels, 24 mA drive, and Ioff - making it superior for multi-rail power sequencing and robust hot-swap interfaces.

FAQ
What is the maximum sink current per output of the SN74LVC07ADR?
The SN74LVC07ADR supports up to 24 mA sink current per output at VCC = 3 V, as specified in the Electrical Characteristics table under IOL conditions. This value decreases slightly at lower VCC (e.g., 4 mA at 1.65 V) but remains sufficient to drive multiple CMOS inputs or small indicator loads without external amplification. The SN74LVC07ADR maintains this capability across its full –40°C to +125°C operating range.
Does the SN74LVC07ADR support level translation between different supply voltages?
Yes, the SN74LVC07ADR supports bidirectional level translation: its inputs accept voltages up to 5.5 V regardless of VCC (1.65–5.5 V), and its open-drain outputs interface with external pull-ups at voltages up to 5.5 V. This allows the SN74LVC07ADR to translate signals from a 1.8 V microcontroller to a 5 V bus or vice versa - without requiring separate level-shifting ICs.
What is the purpose of the Ioff feature in the SN74LVC07ADR?
The Ioff feature in the SN74LVC07ADR disables all outputs when VCC = 0 V, preventing damaging back-current flow through the device during hot-insertion, partial-power-down, or system power sequencing events. This ensures safe operation in modular systems like PCIe cards or hot-swappable SSD modules, where the SN74LVC07ADR may be powered down while other rails remain active.
Can unused inputs on the SN74LVC07ADR be left floating?
No, unused inputs on the SN74LVC07ADR must be tied to either VCC or GND to prevent undefined logic states and excessive current draw. As stated in TI's layout guidelines, floating CMOS inputs can cause oscillation, increased power consumption, or latch-up. For the SN74LVC07ADR, tying unused A-inputs to GND is recommended unless system logic requires a specific high state.
What package type is used for the SN74LVC07ADR?
The SN74LVC07ADR uses a 14-pin SOIC (D) package with 8.65 mm × 3.91 mm body dimensions, 1.27 mm lead pitch, and RoHS-compliant NiPdAu or Sn lead finish. It ships in large tape-and-reel format (2500 units/reel) and is compatible with standard SOIC-14 PCB footprints and reflow soldering profiles per JEDEC J-STD-020.
