Product details
Overview
74LVC07AD/AUJ from Nexperia is a hex buffer IC with six independent open-drain outputs, designed for level translation between 3.3 V and 5 V logic domains. It operates across 1.2 V to 5.5 V supply, features Schmitt-trigger inputs for noise immunity, and supports -40 °C to +125 °C ambient operation - enabling use in industrial I/O expansion, bus buffering, and mixed-voltage interface circuits.
For engineers reviewing the 74LVC07AD/AUJ datasheet, 74LVC07AD/AUJ pinout, 74LVC07AD/AUJ application, or 74LVC07AD/AUJ equivalent, this device is selected for robust open-drain drive capability, 5 V-tolerant inputs, wide VCC range, and JEDEC-compliant voltage thresholds - critical when interfacing microcontrollers with legacy 5 V peripherals or driving LEDs and pull-up-based buses.
Technical Context
The 74LVC07AD/AUJ implements six identical non-inverting buffers, each with an open-drain output stage that requires an external pull-up resistor. Its Schmitt-trigger inputs accept slow-rising signals and reject noise, supporting reliable operation even with RC-filtered or long-trace inputs.
Each buffer switches based on input voltage thresholds defined per VCC range (e.g., VIH = 0.7VCC at 4.5–5.5 V), and output low-level voltage (VOL) remains ≤0.55 V at 32 mA sink current - ensuring solid logic LOW under heavy load while maintaining compatibility with TTL and CMOS families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage (VCC) | 1.2 V to 5.5 V - enables single-supply operation across battery-powered, 3.3 V embedded, and 5 V legacy systems. |
| Input voltage tolerance | Up to 5.5 V - allows direct connection to 5 V outputs without level-shifting circuitry. |
| Output type | Open-drain - supports wired-AND logic, I²C bus termination, LED driving, and multi-master bus arbitration. |
| Propagation delay (tPZL) | 0.5 ns to 3.5 ns (VCC = 4.5–5.5 V) - ensures fast signal routing in timing-critical digital interfaces. |
| Operating temperature | -40 °C to +125 °C - qualified for extended industrial and under-hood automotive auxiliary applications. |
| ESD protection | HBM >2000 V, CDM >1000 V - provides robust handling during PCB assembly and field deployment. |
| Input hysteresis | Typical 0.3 V - suppresses chatter on noisy or slowly transitioning control lines (e.g., pushbutton debouncing). |
Pinout & Package
74LVC07AD/AUJ is supplied in SO14 (SOT108-1) package: plastic small outline, 14-lead, 3.9 mm body width, with standard gull-wing leads and pin 1 index marker.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A, 5A, 6A (Pins 1,3,5,9,11,13) | Data input | Schmitt-trigger buffered inputs accepting 0–5.5 V; tolerant of slow edges and noise. |
| 1Y, 2Y, 3Y, 4Y, 5Y, 6Y (Pins 2,4,6,8,10,12) | Open-drain output | Sinks up to 32 mA per channel; requires external pull-up for HIGH state; enables bus sharing. |
| GND (Pin 7) | Ground reference | 0 V return path for all internal logic and output current; must be low-impedance for noise control. |
| VCC (Pin 14) | Power supply | Single supply rail powering all six buffers; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V-tolerant inputs | Accepts 0–5.5 V input signals regardless of VCC, eliminating need for discrete level shifters in mixed-voltage systems. |
| Wide VCC range (1.2–5.5 V) | Supports direct integration into ultra-low-power (1.2 V/1.8 V) MCUs and legacy 5 V controllers without voltage conversion. |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis to reject noise and ensure clean transitions on slow or noisy control lines (e.g., reset, enable). |
| JEDEC-compliant voltage thresholds | Fully conforms to JESD8-7A, JESD8-5A, and JESD8-C standards - guarantees interoperability with certified logic families. |
| High sink current (32 mA) | Drives LEDs directly or loads such as I²C pull-ups, MOSFET gates, and relay drivers without external transistors. |

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 |
|---|---|---|---|
| 74LVC06AD (Nexperia) | Inverts logic (hex inverter); same VCC range, pinout, and open-drain structure. | Requires logic inversion in signal path; unsuitable where non-inverting buffering is mandatory. | Select only if system design accommodates inverted polarity; otherwise, 74LVC07AD/AUJ is the functional match. |
| SN74LVC07APW (Texas Instruments) | Identical function and electrical specs; packaged in TSSOP14 (SOT402-1) instead of SO14. | Smaller footprint and higher thermal resistance; requires rework of PCB land pattern and stencil. | Choose for space-constrained designs where TSSOP is preferred; verify thermal derating at full load. |
Compared with 74LVC06AD, the 74LVC07AD/AUJ preserves signal polarity essential for control-line buffering; compared with SN74LVC07APW, it offers SO14 mechanical robustness and easier hand-soldering, making it preferable for prototyping and industrial-grade assemblies.

FAQ
What is the maximum output sink current per channel of the 74LVC07AD/AUJ?
The 74LVC07AD/AUJ supports up to 32 mA DC sink current per output channel at VCC = 4.5–5.5 V, with VOL ≤ 0.55 V. This rating is validated across the full -40 °C to +125 °C operating range and enables direct driving of LEDs, MOSFET gates, and relay coils without external amplification. Always observe total package power dissipation limits (500 mW for SO14) when operating multiple channels simultaneously.
Can the 74LVC07AD/AUJ operate with a 1.2 V supply voltage?
Yes, the 74LVC07AD/AUJ is fully specified down to 1.2 V supply voltage, with guaranteed VIH/VIL thresholds and propagation delays at that level. At 1.2 V, typical tPZL is 8.0 ns and input hysteresis remains functional. This makes the 74LVC07AD/AUJ suitable for ultra-low-power battery-operated systems where core logic runs at sub-1.8 V rails.
Does the 74LVC07AD/AUJ require external pull-up resistors on its outputs?
Yes - all six outputs of the 74LVC07AD/AUJ are open-drain and must be pulled up externally to a valid logic HIGH voltage (which may differ from VCC). Pull-up values depend on bus capacitance and speed requirements; typical values range from 1 kΩ (for fast 5 V buses) to 10 kΩ (for low-power 3.3 V I²C). No internal pull-ups are present.
Is the 74LVC07AD/AUJ pin-compatible with older 74HC07 or 74LS07 devices?
No - although functionally similar, the 74LVC07AD/AUJ uses CMOS technology with different voltage thresholds, drive strength, and ESD protection versus bipolar 74LS07 or older 74HC07. Pinout matches standard 14-pin SO logic packages (1A–6A and 1Y–6Y positions), but electrical behavior differs significantly; direct replacement requires validation of timing, noise immunity, and loading conditions in the target circuit.
What JEDEC standards does the 74LVC07AD/AUJ comply with?
The 74LVC07AD/AUJ complies with JEDEC standards JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) for input voltage thresholds and switching characteristics. These ensure interoperability with other JEDEC-certified logic families across multiple supply voltage bands, supporting standardized mixed-voltage system design.
