Product details
Overview
74LVT02D,112 from Nexperia is a 3.3 V quad 2-input NOR gate in SO14 (SOT108-1) package, designed for high-speed logic interfacing with TTL-compatible inputs and 5.5 V overvoltage-tolerant inputs. It delivers ±32 mA/±64 mA output drive, supports partial power-down via IOFF circuitry, and operates across -40 °C to +85 °C for industrial bus interface and control logic applications.
For engineers reviewing the 74LVT02D,112 datasheet, 74LVT02D,112 pinout, 74LVT02D,112 application, or 74LVT02D,112 equivalent, this device is selected for robust 3.3 V logic translation, hot-swap-safe bus isolation, and low-propagation-delay combinational logic in mixed-voltage systems where backflow current prevention and 5 V-tolerant inputs are critical.
Technical Context
This device implements four independent 2-input NOR gates with true complementary CMOS output stages, enabling rail-to-rail switching and bidirectional bus compatibility. Its IOFF circuit actively disables outputs during VCC = 0 V, blocking reverse current up to 5.5 V on inputs/outputs - essential for live-insertion and partial-power-down architectures.
Input thresholds are fixed at VIH ≥ 2.0 V and VIL ≤ 0.8 V across 2.7–3.6 V supply, ensuring reliable TTL-level recognition. Propagation delays are tightly specified: tPLH/tPHL ≤ 4.4 ns / 3.6 ns at VCC = 3.6 V, supporting >100 MHz toggle rates in synchronous control paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 3.6 V - Enables direct use with 3.3 V systems without level-shifting. |
| Output Drive | +64 mA sink / -32 mA source - Drives heavy capacitive loads or multiple TTL inputs without external buffers. |
| Input Voltage Range | 0 V to 5.5 V - Accepts 5 V logic signals safely while powered from 3.3 V, eliminating external clamping diodes. |
| Propagation Delay | Max 4.4 ns (tPLH), 3.6 ns (tPHL) at VCC = 3.6 V - Supports sub-5 ns timing-critical control paths in FPGA/CPU glue logic. |
| IOFF Leakage | ±100 μA at VCC = 0 V - Prevents damaging backfeed current when powered down in live-backplane environments. |
| Operating Temperature | -40 °C to +85 °C - Qualified for industrial-grade embedded controllers and telecom line cards. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - Withstands handling and board-level ESD events without protection circuitry overhead. |
Pinout & Package
74LVT02D,112 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm pitch, gull-wing leads. Pin 1 marked by notch or bevel; pin 1 index located at top-left corner of package top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | 1Y, 2Y, 3Y, 4Y | Active-low NOR outputs - Each drives one logic channel; compatible with 5 V buses when tied to 5 V via pull-up. |
| 2, 5, 8, 11 | 1A, 2A, 3A, 4A | First input per gate - TTL-compatible threshold; accepts 5 V inputs without damage or level shifters. |
| 3, 6, 9, 12 | 1B, 2B, 3B, 4B | Second input per gate - Fully symmetrical with A inputs; enables flexible gate configuration (e.g., OR/NOR inversion). |
| 7 | GND | Ground reference - Must be low-impedance connection to minimize ground bounce in high-speed switching. |
| 14 | VCC | 3.3 V supply - Requires local 100 nF ceramic decoupling adjacent to pin to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Partial Power-Down (IOFF) | Outputs enter high-impedance state at VCC = 0 V, preventing backflow current from 5 V buses into unpowered sections. |
| 5.5 V Overvoltage-Tolerant Inputs | Inputs withstand 5.5 V regardless of VCC state - eliminates need for external voltage translators in mixed-supply systems. |
| Power-Up 3-State | Outputs remain in high-Z until VCC stabilizes above 1.5 V - prevents bus contention during power sequencing. |
| TTL-Compatible Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 2.7–3.6 V - ensures reliable recognition of legacy 5 V TTL signals. |
| High Sink/Source Current | 64 mA sink capability allows direct driving of LEDs, relays, or multiple 74-series loads without buffer stages. |
Applications
| Industrial PLC I/O Expansion | Legacy System Bus Interface |
|---|---|
Use Scenario: Adding discrete digital output channels to programmable logic controllers using 3.3 V microcontrollers while retaining 5 V field-side signaling. IC Role / Device Role / Timing Role: NOR gate provides active-low enable logic for opto-isolated relay drivers; IOFF prevents backfeed when controller resets. Use Value: Eliminates level-shifters and external clamps, reducing BOM count and PCB area while maintaining 5 V bus integrity during hot-swap events. |
Use Scenario: Interfacing modern 3.3 V FPGAs to legacy 5 V parallel data buses (e.g., ISA, PC/104) in test equipment upgrades. IC Role / Device Role / Timing Role: Acts as bidirectional bus transceiver element - NOR gates configure as inverters or wired-OR logic for address/data strobing. Use Value: 4.4 ns max propagation delay meets 20 MHz bus timing; 5.5 V-tolerant inputs accept legacy bus voltages without signal degradation. |
| Telecom Line Card Control Logic | Automated Test Equipment (ATE) Signal Conditioning |
Use Scenario: Implementing fault-detection combinatorial logic on high-density telecom line cards where thermal management limits active components. IC Role / Device Role / Timing Role: Four NOR gates perform real-time AND/NOR logic on alarm, reset, and sync signals to generate priority interrupt vectors. Use Value: Low ICC (≤2 mA) and no external biasing reduce static power; SO14 footprint fits tight spacing constraints near ASICs/FPGAs. |
Use Scenario: Generating synchronized enable pulses for multi-channel D/A converters in precision ATE systems requiring deterministic setup/hold margins. IC Role / Device Role / Timing Role: NOR gates form edge-triggered monostables and pulse-width modulators controlling DAC update timing and calibration sequencing. Use Value: Matched tPLH/tPHL (≤0.8 ns skew) ensures sub-nanosecond inter-channel timing alignment critical for <12-bit accuracy. |
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 (1.65–3.6 V); lower drive (±24 mA); no IOFF or 5.5 V tolerance | Suitable only for pure 3.3 V or 2.5 V systems; requires external clamping for 5 V inputs | Select when cost sensitivity outweighs mixed-voltage robustness and bus isolation needs. |
| 74ALVC02PW,118 | Same SO14 package; 1.65–3.6 V supply; ±24 mA drive; no IOFF; 5.5 V tolerant inputs retained | Lacks power-down isolation - unsuitable for hot-plug or partial-power architectures | Choose only for space-constrained 3.3 V-only designs where IOFF is not required and 5 V input tolerance remains essential. |
Compared with SN74LVC02APWR and 74ALVC02PW,118, the 74LVT02D,112 uniquely combines 5.5 V input tolerance, IOFF-enabled bus isolation, and +64 mA sink strength - making it the sole option for industrial backplanes and legacy bus adapters requiring both voltage interoperability and safe power sequencing.

FAQ
Does 74LVT02D,112 support hot-swap insertion into a live 5 V bus?
Yes - its IOFF circuitry disables outputs when VCC = 0 V, limiting backflow current to ±100 μA even with 5.5 V applied to inputs or outputs. This meets IEC 61000-4-2 Level 3 ESD immunity requirements and prevents damage during live insertion into powered backplanes.
Can 74LVT02D,112 drive a 5 V pull-up resistor directly without damage?
Yes - the outputs tolerate 5 V in HIGH or OFF states per absolute maximum ratings (VO ≤ +7.0 V), and the 5.5 V overvoltage-tolerant inputs allow direct connection to 5 V buses. No external clamping diodes or level shifters are needed for 5 V bus tie-off.
What is the minimum supply voltage for guaranteed TTL-level input recognition?
The device guarantees VIH ≥ 2.0 V and VIL ≤ 0.8 V across the full 2.7–3.6 V supply range. At VCC = 2.7 V, VIH remains ≥ 2.0 V, ensuring reliable detection of standard TTL HIGH (≥ 2.0 V) and LOW (≤ 0.8 V) signals without margin loss.
Is the SO14 package (SOT108-1) pinout identical between 74LVT02D and 74LVT02PW?
Yes - both share identical pin numbering and functional assignment per Figures 4 and 5 in the datasheet. The SOT108-1 (SO14) and SOT402-1 (TSSOP14) packages are functionally and electrically interchangeable; only mechanical dimensions and thermal resistance differ.
