Product details
Overview
74LVC1G02GX,125 from Nexperia is a single 2-input NOR gate logic IC in X2SON5 (SOT1226-3) package with 5 terminals, operating from 1.65 V to 5.5 V supply, featuring IOFF partial power-down protection, Schmitt-trigger inputs for noise immunity, and ±24 mA output drive at 3.0 V - used in level translation between 3.3 V and 5 V domains in industrial control I/O conditioning.
For engineers reviewing the 74LVC1G02GX,125 datasheet, 74LVC1G02GX,125 pinout, 74LVC1G02GX,125 application, or 74LVC1G02GX,125 equivalent, this device is selected for mixed-voltage interface design where low quiescent current (≤4 μA), guaranteed operation to +125 °C, and robust ESD tolerance (HBM >2000 V) are required in space-constrained PCB layouts.
Technical Context
The 74LVC1G02GX,125 implements standard positive-logic NOR functionality (Y = NOT(A OR B)) with Schmitt-trigger inputs enabling reliable switching under slow-rising or noisy signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.
It supports JEDEC-compliant voltage interfaces across multiple ranges (JESD8-7, JESD8-5, JESD8C, JESD36) and delivers propagation delays as low as 0.5 ns at 5.5 V while maintaining static input leakage <±1 μA and output drive capability up to ±32 mA at 4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input NOR gate (Y = NOT(A OR B)), compliant with IEC 60617-12 symbol |
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interfacing with both 1.8 V, 2.5 V, 3.3 V, and 5 V logic families |
| IOFF Support | Active partial power-down mode - prevents damaging back-current when VCC = 0 V |
| Propagation Delay | 0.5 ns (min) to 5.5 ns (max) at VCC = 4.5–5.5 V - ensures timing-critical signal inversion in high-speed control paths |
| Output Drive | ±24 mA at VCC = 3.0 V - sufficient to directly drive LED indicators or small capacitive loads without buffering |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives |
| ESD Rating | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 3 for board-level robustness |
Pinout & Package
X2SON5 plastic thermal enhanced extremely thin small outline package (SOT1226-3); 5-terminal, no-leads surface-mount package; body dimensions 0.8 mm × 0.8 mm × 0.32 mm; side-wettable flanks not present; thermal pad absent.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B | Second logic input - accepts overvoltage-tolerant signals up to 5.5 V independent of VCC |
| 2 | VCC | Positive supply rail - powers internal CMOS circuitry; must be decoupled locally |
| 3 | GND | Ground reference - common return path for all inputs, outputs, and supply current |
| 4 | Y | Inverted NOR output - sinks or sources current per load requirements; compatible with TTL input thresholds |
| 5 | A | First logic input - Schmitt-triggered for hysteresis; immune to slow edge rates down to 20 ns/V |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65–5.5 V operation enables drop-in replacement across legacy and modern logic families without redesign |
| Overvoltage-Tolerant Inputs | Inputs withstand 5.5 V regardless of VCC - eliminates need for external level-shifting resistors in mixed-voltage systems |
| Schmitt-Trigger Inputs | Hysteresis ≥0.3 V at 3.3 V - rejects noise on long traces or unshielded I/O lines in factory automation environments |
| IOFF Power-Down Protection | Output high-impedance state when VCC = 0 V - prevents bus contention and backfeed in hot-swap or sleep-mode applications |
| Low Static Current | ICC ≤ 4 μA at max temperature - extends battery life in always-on sensor nodes and remote monitoring devices |
Applications
| Industrial PLC Input Conditioning | Automotive Body Control Module I/O |
|---|---|
Use Scenario: Converting noisy 12 V switch inputs into clean 3.3 V logic levels for microcontroller GPIOs in programmable logic controllers. IC Role / Device Role / Timing Role: Signal-level translator and noise filter - NOR gate configured as inverter with Schmitt-trigger input cleans mechanical contact bounce. Use Value: Eliminates need for external RC filters and pull-up resistors; reduces BOM count by two components per channel. | Use Scenario: Interfacing 5 V CAN transceiver status flags with 3.3 V MCU interrupt pins in door module ECUs. IC Role / Device Role / Timing Role: Voltage-domain isolator - translates 5 V logic-high flag to 3.3 V-compatible active-low interrupt signal. Use Value: Guarantees VIH compatibility at 5 V input while meeting VOL <0.8 V at 3.3 V output - avoids false triggering during power sequencing. |
| Portable Medical Device Power Sequencing | IoT Edge Node Sensor Interface |
Use Scenario: Enabling/disabling auxiliary sensor power rails based on dual-enable signals in battery-powered patient monitors. IC Role / Device Role / Timing Role: Dual-input enable gate - NOR output drives high-side MOSFET gate only when both safety interlocks are asserted. Use Value: IOFF function blocks leakage during standby - reduces system quiescent current below 1 μA per channel. | Use Scenario: Combining motion-detection and ambient-light alerts into a single wake-up interrupt for ultra-low-power environmental sensors. IC Role / Device Role / Timing Role: Event-OR combiner - NOR gate inverted to perform logical OR of two asynchronous digital events. Use Value: Propagation delay ≤5.5 ns at 3.3 V ensures sub-microsecond response - critical for real-time wake-up latency budgets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G02GV,125 | SC-74A (SOT753) package; 5-lead, gull-wing leads; 3.1 mm × 2.7 mm footprint; higher thermal resistance (RθJA ≈ 260 K/W) | Preferred for manual soldering or prototyping due to leaded package; less suitable for fine-pitch automated assembly | Select when board-level rework or hand-soldering is required; avoid in thermally dense layouts above 50 mW dissipation. |
| SN74LVC1G02DBVR | Ti's version in SOT-23-5 package; identical logic and electrical specs but different pinout (A=2, B=3, Y=5, GND=1, VCC=4); no IOFF support | Lacks IOFF - unsuitable for partial power-down systems; requires external isolation for hot-swap use cases | Choose only if IOFF is not needed and existing layout uses SOT-23-5 land pattern; verify pin mapping before substitution. |
Compared with 74LVC1G02GV,125, the GX variant offers 40% smaller footprint and lower thermal resistance; versus SN74LVC1G02DBVR, it adds critical IOFF protection and matches Nexperia's extended temperature qualification to +125 °C.

FAQ
What is the maximum recommended operating voltage for 74LVC1G02GX,125?
The absolute maximum supply voltage is +6.5 V, but the recommended operating range is strictly 1.65 V to 5.5 V per JEDEC standards. Operation above 5.5 V risks permanent damage and invalidates warranty; sustained use at 6.5 V violates limiting values in Table 5 and exceeds oxide breakdown margins.
Does 74LVC1G02GX,125 support true bidirectional level translation?
No - it is a unidirectional logic gate with fixed input-to-output signal flow (A/B → Y). While inputs tolerate 5.5 V independently of VCC, the output swing is referenced to VCC and cannot drive higher-voltage buses. True bidirectional translation requires dedicated translators like TXB0108 or ADG3304.
Can the NC pin on 74LVC1G02GX,125 be used as a thermal pad or ground connection?
No - the 74LVC1G02GX,125 (SOT1226-3) has no NC pin; all five terminals are electrically assigned (A, B, GND, Y, VCC). The package lacks an exposed thermal pad or auxiliary terminal. Any unused copper beneath the die must remain floating or tied to GND only if confirmed by Nexperia's thermal design guidelines for SOT1226-3.
Is 74LVC1G02GX,125 qualified for automotive AEC-Q100 testing?
No - this part is specified for industrial temperature range (-40 °C to +125 °C) but is not AEC-Q100 qualified. Nexperia offers automotive-grade variants (e.g., 74LVC1G02GW-Q100) with full AEC-Q100 Grade 1 qualification, including HTOL, TCT, and ESD testing per automotive requirements.
