Product details
Overview
74LVC1G14GW,125 from Nexperia is a single Schmitt-trigger inverter IC designed for signal conditioning in mixed-voltage digital systems. It operates from 1.65 V to 5.5 V, accepts overvoltage-tolerant inputs up to 5.5 V, delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and is rated for -40 °C to +125 °C operation. It enables robust noise-immune waveform shaping in level-translating interfaces between 3.3 V and 5 V logic domains.
For engineers reviewing the 74LVC1G14GW,125 datasheet, 74LVC1G14GW,125 pinout, 74LVC1G14GW,125 application, or 74LVC1G14GW,125 equivalent, this device serves as a compact, rail-to-rail compatible inverter for pulse edge sharpening, oscillator circuits, and bus isolation where hysteresis and low-power CMOS performance are required.
Technical Context
The 74LVC1G14GW,125 implements a single-channel Schmitt-trigger inverter with asymmetric input thresholds (VT+ = 1.29 V, VT− = 0.88 V at VCC = 3.0 V) and 0.41 V typical hysteresis, enabling reliable noise rejection on slow-rising signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.
It supports unlimited input rise/fall times without shoot-through risk and maintains full functionality across JEDEC-compliant voltage ranges (JESD8-7 through JESD36). Static input leakage remains ≤±1 μA, and propagation delay is 3.0 ns typical (VCC = 3.3 V), making it suitable for timing-critical relaxation oscillators and monostable multivibrators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct interface between 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without external level shifters. |
| Input Thresholds (VCC = 3.0 V) | VT+ = 1.29 V, VT− = 0.88 V - Provides 410 mV hysteresis for noise margins >200 mV in noisy industrial environments. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to directly drive multiple 74LVC inputs or small capacitive loads (<50 pF) without buffering. |
| Propagation Delay | 3.0 ns typical (VCC = 3.3 V) - Supports clean signal inversion up to ~100 MHz in non-clocked applications like pulse shaping. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - Prevents damaging backfeed current during hot-swap or partial power-down sequences in modular systems. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Meets IEC 61000-4-2 Level 3 requirements for handling in automated assembly lines. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood automotive, industrial PLC, and outdoor IoT node deployments. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm lead pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - left floating; no PCB trace or thermal pad required. |
| 2 | A | Inverting input with Schmitt-trigger hysteresis - accepts slow edges and rejects noise below VT− or above VT+. |
| 3 | GND | Digital ground reference - must be connected to system 0 V plane with low-inductance path for stable threshold behavior. |
| 4 | Y | Inverted output - drives complementary logic levels with rail-to-rail swing and ±24 mA sourcing/sinking capability. |
| 5 | VCC | Positive supply - powers internal CMOS structure; requires local 100 nF ceramic decoupling within 3 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65–5.5 V operation eliminates need for separate voltage regulators in multi-rail systems. |
| Overvoltage-Tolerant Inputs | Withstands 5.5 V inputs regardless of VCC level - enables safe interfacing with legacy 5 V microcontrollers or sensors. |
| IOFF Partial Power-Down | Outputs go high-impedance when VCC = 0 V - prevents back-current damage during board-level power sequencing. |
| High Noise Immunity | 410 mV hysteresis at 3.0 V supply ensures reliable switching in EMI-prone motor control or power supply feedback paths. |
| Low Dynamic Power | 15.4 pF CPD and <4 μA ICC enable battery-operated sensor nodes to achieve >10-year shelf life in sleep mode. |
Applications
| Wave and Pulse Shaper | Astable Multivibrator |
|---|---|
|
Use Scenario: Converting noisy or slow-rising analog sensor outputs (e.g., thermistor divider, hall-effect switch) into clean digital pulses for MCU GPIO capture. IC Role / Device Role / Timing Role: Schmitt-trigger inverter acting as edge-sharpening front-end with fixed hysteresis to suppress contact bounce or EMI-induced glitches. Use Value: Eliminates need for external RC filtering and software debouncing, reducing BOM count and firmware complexity in cost-sensitive consumer devices. |
Use Scenario: Generating precise square-wave clock signals in standalone timing circuits where crystal oscillators are overkill. IC Role / Device Role / Timing Role: Core inverter in two-stage ring oscillator configuration with external R-C network defining frequency via K-factor (Fig. 11). Use Value: Delivers stable 1–100 kHz clocks with <5% tolerance using only one IC and two passive components - ideal for LED flashers or fan controllers. |
| Monostable Multivibrator | Level Translation Interface |
|
Use Scenario: Creating fixed-duration pulses from momentary button presses or interrupt signals in embedded control panels. IC Role / Device Role / Timing Role: Inverter-based one-shot circuit where input trigger initiates capacitor discharge cycle, generating programmable pulse width. Use Value: Achieves 10 μs–1 s pulse widths with <10% drift over temperature - replaces dedicated 555 timers in space-constrained designs. |
Use Scenario: Interfacing 5 V legacy peripherals (e.g., RS-232 transceivers, industrial sensors) with 3.3 V or 1.8 V microcontrollers. IC Role / Device Role / Timing Role: Bidirectional level translator leveraging overvoltage-tolerant inputs and rail-swing outputs without direction control pins. Use Value: Enables drop-in replacement of discrete MOSFET translators with guaranteed timing alignment and lower layout sensitivity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G14DBVR | Same logic function and 1.65–5.5 V range, but in SOT-23-5 package with different pinout (VCC = pin 5, GND = pin 2); lacks side-wettable flanks. | Compatible in signal integrity and timing, but requires PCB redesign due to non-identical footprint and thermal profile. | Select when existing SOT-23-5 land pattern is fixed and reflow inspection via optical means is preferred over X-ray. |
| 74AUP1G14GW,125 | Lower static current (0.9 μA vs. 4 μA) and reduced CPD (11.5 pF), but narrower VCC range (0.8–3.6 V) and no 5 V input tolerance. | Suitable only for ultra-low-power 1.8/2.5/3.3 V systems; cannot replace in mixed 3.3/5 V environments requiring input overvoltage safety. | Choose for battery-powered wearables where sub-μA quiescent current outweighs voltage flexibility requirements. |
Compared with SN74LVC1G14DBVR and 74AUP1G14GW,125, the 74LVC1G14GW,125 uniquely balances 5 V input tolerance, industrial temperature range, and TSSOP5 manufacturability - making it the default choice for automotive body electronics and industrial HMI interfaces where reliability and legacy compatibility are mandatory.

FAQ
Does the 74LVC1G14GW,125 support true bidirectional level translation?
No - it is a unidirectional inverter with overvoltage-tolerant inputs. While it accepts 5 V inputs when powered from 3.3 V, its output swings only between 0 V and the applied VCC. For true bidirectional translation, a dedicated dual-supply translator like NXH010P120MNQ is required.
Can the 74LVC1G14GW,125 be used in an oscillator circuit without external resistors?
No - the device itself has no internal feedback path. All oscillator configurations (astable or monostable) require external passive components: at minimum one resistor and one capacitor connected between input and output to establish timing and sustain oscillation per Figure 10.
What is the maximum capacitive load the 74LVC1G14GW,125 can drive reliably?
At VCC = 3.3 V and Tamb = 25 °C, the output maintains ≤5.5 ns propagation delay with 50 pF load (Table 9). Driving >100 pF risks excessive rise/fall times and increased dynamic power; add series termination or buffer stages for heavier loads.
Is the n.c. pin on the TSSOP5 package electrically isolated or internally tied?
Pin 1 is confirmed as no-connect - no internal bond wire or silicon connection exists. It may be left unconnected on PCB, though grounding it improves mechanical stability during reflow. Do not route signals or power to this pin.
