Product details
Overview
74LVC1G02GW,125 from Nexperia is a single 2-input NOR gate logic IC in TSSOP5 (SOT353-1) package, operating from 1.65 V to 5.5 V supply, featuring Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, 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 74LVC1G02GW,125 datasheet, 74LVC1G02GW,125 pinout, 74LVC1G02GW,125 application, or 74LVC1G02GW,125 equivalent, this device serves as a robust, low-power, overvoltage-tolerant logic gate for mixed-voltage interface design, ESD-hardened signal routing, and power-gated subsystem isolation where input rise/fall time tolerance and backflow current prevention are critical.
Technical Context
The 74LVC1G02GW implements standard positive-logic NOR functionality (Y = NOT(A OR B)) with Schmitt-trigger inputs enabling reliable operation with slow or noisy signals. Its IOFF circuit actively disables outputs during power-down, blocking reverse current flow when VCC = 0 V.
It supports JEDEC-compliant voltage interfaces across four ranges (1.65–1.95 V, 2.3–2.7 V, 2.7–3.6 V, 4.5–5.5 V), maintains TTL-level compatibility, and delivers propagation delays as low as 0.5 ns at 5.5 V while sustaining full operation from –40 °C to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input NOR gate (Y = NOT(A OR B)), enabling basic combinational logic and enable/inhibit control. |
| Supply Voltage Range | 1.65 V to 5.5 V - allows direct interfacing with 1.8 V, 2.5 V, 3.3 V, and 5 V systems without level shifters. |
| Input Overvoltage Tolerance | Inputs withstand up to 5.5 V regardless of VCC - supports safe 5 V-tolerant operation in 3.3 V domains. |
| IOFF Current | ±2 μA max at VCC = 0 V - prevents damaging backflow current during hot-insertion or partial power-down sequences. |
| Propagation Delay | 0.5 ns (min) to 5.5 ns (max) at VCC = 4.5–5.5 V - ensures timing-critical signal inversion with sub-6 ns worst-case latency. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - drives moderate capacitive loads and multiple CMOS/TTL inputs without buffering. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets industrial-grade ESD robustness requirements per JS-001/JS-002. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, body width 1.25 mm, 0.65 mm pitch, rated for –40 °C to +125 °C operation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B | Second logic input; Schmitt-triggered for noise margin and slow-edge tolerance. |
| 2 | A | Primary logic input; electrically identical to Pin 1, supports independent signal routing. |
| 3 | GND | Ground reference (0 V); must be low-impedance for stable logic thresholds and ESD discharge path. |
| 4 | Y | Inverted NOR output; capable of sourcing/sinking ±24 mA at 3.0 V with rail-to-rail swing. |
| 5 | VCC | Positive supply; powers internal circuitry and defines logic threshold levels (VIH/VIL scale with VCC). |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable switching with slow-rising/falling signals (Δt/ΔV ≤ 20 ns/V at 1.65–2.7 V), reducing false triggering in noisy environments. |
| IOFF partial power-down | Disables output high-impedance state when VCC = 0 V, eliminating backfeed current in multi-rail systems during sequencing or fault conditions. |
| Wide voltage interoperability | Accepts 5 V inputs while powered from 1.65 V - eliminates external translators in mixed-voltage FPGA/CPU peripheral interfaces. |
| High noise immunity | Input hysteresis ≥ 0.35VCC (typ.) ensures >300 mV noise margin at 3.3 V, suppressing glitches on shared PCB traces. |
| Thermal-enhanced packaging | TSSOP5 (SOT353-1) provides 3.3 mW/K derating above 74 °C - supports sustained operation in compact industrial enclosures. |
Applications
| Industrial PLC I/O Conditioning | Automotive Body Control Module Logic |

Use Scenario: Isolating and translating sensor status signals (e.g., door open/closed, seatbelt latch) before feeding into microcontroller GPIOs with mixed 3.3 V/5 V supply rails. IC Role / Device Role / Timing Role: NOR gate performs active-low enable logic and signal inversion; Schmitt inputs reject EMI from solenoid drivers and motor noise. Use Value: Eliminates need for discrete RC filters or dedicated level shifters, reducing BOM count and board space in constrained BCM modules. |
Use Scenario: Debouncing mechanical switch inputs (e.g., ignition key sense, hazard light toggle) in non-safety-critical vehicle subsystems. IC Role / Device Role / Timing Role: Provides clean, glitch-free logic output using hysteresis; IOFF prevents backfeed when main MCU rail is powered down during sleep mode. Use Value: Enables zero-current standby state without external isolation MOSFETs, extending battery life in always-on vehicle networks. |
| Medical Device Power Sequencing | IoT Edge Node Signal Routing |
|
Use Scenario: Controlling enable lines for analog front-end (AFE) and communication ICs during controlled power-up/down sequences in portable diagnostics equipment. IC Role / Device Role / Timing Role: NOR gate acts as an OR-invert supervisor - asserts reset when any supply falls below threshold or when shutdown command is issued. Use Value: Ensures deterministic power-state transitions with no race conditions, meeting IEC 62304 software safety requirements for Class II devices. |
Use Scenario: Managing wake-up signal arbitration between BLE SoC, environmental sensors, and motion detectors in battery-powered smart sensors. IC Role / Device Role / Timing Role: Combines multiple interrupt sources into a single wake line; low ICC (≤4 μA) minimizes quiescent current drain during deep sleep. Use Value: Reduces average system current by >15% versus discrete transistor solutions, extending coin-cell lifetime beyond 5 years. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G02GV | Same logic function and electrical specs; SC-74A (SOT753) package with 0.95 mm body width and 0.95 mm lead pitch. | Lower thermal resistance than TSSOP5 but larger footprint; suited for manual assembly or reflow with less stringent placement accuracy. | Select when board-level rework accessibility or legacy pick-and-place compatibility outweighs size constraints. |
| SN74LVC1G02DBVR | TI part in SOT-23-5 (DBV) package; identical VCC range and IOFF, but lacks Schmitt-trigger inputs and has higher VIH/VIL thresholds. | Requires cleaner input edges; unsuitable for slow-switching or high-noise environments without external filtering. | Choose only if existing TI-design ecosystem mandates pin-for-pin replacement and signal integrity is guaranteed. |
Compared with 74LVC1G02GV, the 74LVC1G02GW offers superior board density and thermal performance in TSSOP5; versus SN74LVC1G02DBVR, it delivers essential Schmitt-trigger noise immunity and broader input voltage tolerance critical for real-world industrial signal conditioning.

FAQ
Can 74LVC1G02GW,125 operate with 1.8 V supply and accept 3.3 V inputs?
Yes. The device is fully specified from 1.65 V to 5.5 V supply and features overvoltage-tolerant inputs rated to 5.5 V - enabling safe 3.3 V input signaling while powered from 1.8 V, without clamping diodes or external resistors.
What is the maximum capacitive load the output can drive at 3.3 V?
At VCC = 3.3 V, the output sustains ≤4.5 ns propagation delay with 50 pF load (per datasheet Table 10). For reliable timing, keep total load capacitance ≤50 pF including trace and input capacitance of downstream devices.
Does the IOFF feature work when VCC is disconnected but GND remains connected?
Yes. IOFF activates when VCC = 0 V, regardless of GND connection status. Output impedance exceeds 10 MΩ, limiting leakage to ±2 μA - preventing backflow into powered sections even with floating or grounded GND.
Is 74LVC1G02GW,125 qualified for automotive applications?
No. While rated for –40 °C to +125 °C, it is not AEC-Q100 qualified. Nexperia offers automotive-grade variants (e.g., 74LVC1G02GW-Q100) with enhanced reliability testing and PPAP documentation for vehicle use.
