Product details
Overview
74LVT02DB,118 from Nexperia is a 3.3 V quad 2-input NOR gate in SO14 (SOT108-1) package, featuring IOFF partial power-down protection, ±64 mA/–32 mA output drive, 5.5 V overvoltage-tolerant inputs, and operation from –40 °C to +85 °C. It serves as a level-shifting logic buffer in mixed-voltage digital interfaces such as FPGA I/O expansion and industrial control backplanes.
For engineers reviewing the 74LVT02DB,118 datasheet, 74LVT02DB,118 pinout, 74LVT02DB,118 application, or 74LVT02DB,118 equivalent, this device is selected for robust 3.3 V TTL-compatible logic translation with bus-hold immunity and zero current leakage during system sleep states.
Technical Context
The 74LVT02DB,118 implements four independent NOR gates with complementary CMOS output stages, supporting true 3.3 V operation while accepting 5 V-tolerant inputs without external clamping. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking reverse current flow into powered-down subsystems.
Propagation delays are specified at 2.6 ns (tPHL) and 2.8 ns (tPLH) under 3.3 V/25 °C conditions, with input transition rate tolerance up to 10 ns/V. Static characteristics include VIH ≥ 2.0 V, VIL ≤ 0.8 V, VOH ≥ 2.0 V at –20 mA, and VOL ≤ 0.5 V at 32 mA - enabling direct interconnection with legacy 5 V TTL and modern low-voltage ASICs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.7 V to 3.6 V - ensures compatibility with 3.3 V ±10 % rails and eliminates need for external regulators |
| Output drive | +64 mA sink / –32 mA source - supports driving multiple TTL loads or short PCB traces without buffering |
| Input voltage range | 0 V to 5.5 V - enables safe interfacing with 5 V microcontrollers and sensors without level shifters |
| Propagation delay | 2.6 ns (tPHL), 2.8 ns (tPLH) at 3.3 V - meets timing budgets for sub-200 MHz synchronous logic designs |
| IOFF leakage | ±100 μA at VCC = 0 V - prevents backfeed current that could disrupt adjacent powered circuits during partial shutdown |
| Operating temperature | –40 °C to +85 °C - qualified for industrial ambient environments including factory automation and telecom infrastructure |
| ESD rating | HBM > 2000 V, CDM > 1000 V - exceeds JEDEC JS-001/JS-002 Class 2/C3 for assembly-line robustness |
Pinout & Package
74LVT02DB,118 uses the SO14 plastic small outline package (SOT108-1), 14-pin, 3.9 mm body width, with gull-wing leads and standard 1.27 mm pitch. Pin 1 is marked by notch or bevel; pin 7 is GND, pin 14 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | 1Y, 2Y, 3Y, 4Y | Active-low NOR outputs - each drives one logic node; IOFF disables all when VCC = 0 V |
| 2, 5, 8, 11 | 1A, 2A, 3A, 4A | First input per gate - accepts 0–5.5 V; no external pull-up required due to TTL-compatible thresholds |
| 3, 6, 9, 12 | 1B, 2B, 3B, 4B | Second input per gate - identical electrical behavior to A inputs; supports wired-OR configurations |
| 7 | GND | Ground reference - must be connected before VCC to prevent latch-up; shared return for all four gates |
| 14 | VCC | 3.3 V supply - powers internal logic and output drivers; decoupling capacitor (100 nF) required within 5 mm |
Key Features
| Feature | Design Value |
|---|---|
| Partial power-down (IOFF) | Outputs enter high-impedance state at VCC = 0 V, eliminating back-current risk in hot-swap or multi-rail systems |
| Overvoltage-tolerant inputs | Withstands 5.5 V on any input regardless of VCC state - enables direct connection to 5 V buses without series resistors |
| Power-up 3-state | Outputs remain high-Z until VCC stabilizes above 1.5 V - prevents bus contention during power sequencing |
| TTL-level compatibility | VIH = 2.0 V min, VIL = 0.8 V max - interoperates with 74LS, 74ALS, and microcontroller GPIOs without translation |
| Low dynamic power | ICC < 2 mA at 3.6 V with all outputs loaded - reduces thermal load in dense logic arrays and battery-backed modules |
Applications
| Industrial PLC Backplane Interface | FPGA I/O Expansion Logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC02APWR | Wider VCC range (1.65–5.5 V); lower drive (±24 mA); no IOFF | Lacks partial power-down protection; unsuitable for systems requiring live insertion or rail sequencing | Select only if full-system power cycling is guaranteed and 5 V operation is mandatory |
| 74ALVC02PW,118 | Same SOT402-1 package; identical IOFF and 5.5 V input tolerance; slightly higher ICC (max 4 mA) | Pin-compatible TSSOP variant - used where board space constraints favor thinner profile over SO14 | Choose for footprint-constrained layouts; otherwise SO14 (74LVT02DB,118) offers better thermal dissipation |
Compared with SN74LVC02APWR and 74ALVC02PW,118, the 74LVT02DB,118 uniquely balances 3.3 V optimized speed, 5 V input tolerance, and IOFF-enabled system-level power management - making it the preferred choice for industrial backplanes and FPGA interface isolation where rail sequencing integrity is critical.

FAQ
Can 74LVT02DB,118 be used with 5 V microcontrollers?
Yes - its inputs tolerate up to 5.5 V regardless of VCC level, allowing direct connection to 5 V microcontroller GPIOs without external components. Output levels remain compatible with 3.3 V logic families, and the device draws supply only from its 3.3 V rail.
Does 74LVT02DB,118 require external pull-up resistors on inputs?
No - its TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) allow direct connection to open-collector or push-pull sources without pull-ups. The device does not include internal pull-ups, but external resistors are unnecessary for standard logic driving.
What happens to outputs during power-down?
When VCC drops to 0 V, the IOFF circuit forces all four outputs (pins 1, 4, 10, 13) into high-impedance state, limiting leakage to ±100 μA. This prevents back-current from 5 V buses into unpowered sections, satisfying IEC 61000-4-2 system-level ESD resilience requirements.
Is 74LVT02DB,118 pin-compatible with other 74LVT02 variants?
Yes - all 74LVT02 variants (SO14, TSSOP14, SSOP14) share identical pinout per JEDEC MS-012 and MO-153 standards. The 74LVT02DB,118 (SO14) matches pin-for-pin with 74LVT02PW,118 (TSSOP14) and legacy 74LVT02D, enabling drop-in replacement where package height allows.
