Product details
Overview
74LV14D,118 from Nexperia is a low-voltage CMOS hex inverting Schmitt trigger IC with 14-pin SO14 (SOT108-1) package, operating from 1.0 V to 5.5 V supply, delivering six independent hysteresis-enabled inverters for noise-immune signal conditioning. It transforms slow-rising/falling inputs into clean digital outputs and supports TTL-level inputs at VCC = 2.7–3.6 V - widely used in industrial sensor interface and clock conditioning circuits.
For engineers reviewing the 74LV14D,118 datasheet, 74LV14D,118 pinout, 74LV14D,118 application, or 74LV14D,118 equivalent, this page delivers verified functional identity, validated SO14 pin mapping, confirmed Schmitt-trigger hysteresis behavior (VH ≥ 0.3 V at VCC = 2.0 V), propagation delay ≤ 22 ns at 3.3 V, and real-world multivibrator and waveform shaping use cases - all grounded in Nexperia's Rev. 10 (Jan 2024) product data sheet.
Technical Context
The 74LV14D implements six independent CMOS inverting Schmitt triggers, each with asymmetric input thresholds (VT+ and VT−) enabling hysteresis-based noise rejection. Its input stage accepts both CMOS and TTL logic levels across its full 1.0–5.5 V VCC range, and output drive capability meets ±25 mA absolute maximum ratings with guaranteed VOH > 2.4 V and VOL < 0.4 V at 3.0 V/−6 mA/+6 mA.
Dynamic performance is characterized by propagation delays of 13 ns (typical, CL = 15 pF, VCC = 3.3 V) and power dissipation capacitance CPD = 15 pF, supporting reliable operation up to 5.5 V while maintaining latch-up immunity exceeding 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 5.5 V - enables direct interfacing with 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Hysteresis Voltage (VH) | ≥ 0.3 V at VCC = 2.0 V - ensures robust noise margin against EMI and ground bounce in industrial environments. |
| Propagation Delay (tpd) | ≤ 22 ns at VCC = 3.3 V, CL = 15 pF - supports reliable timing in sub-25 MHz oscillator and pulse-shaping applications. |
| Output Drive Strength | ±6 mA at VCC = 3.0 V - sufficient to directly drive LEDs, small capacitive loads, or subsequent logic stages without buffering. |
| Input Thresholds (VT+, VT−) | VT+ = 1.60 V, VT− = 1.05 V at VCC = 3.0 V - defines precise switching windows for stable edge detection in noisy analog-to-digital interfaces. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and high-reliability embedded control. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - reduces risk of field failure during handling and board assembly in automated manufacturing. |
Pinout & Package
74LV14D,118 is housed in a plastic small outline package (SO14, SOT108-1) with 14 leads, 3.9 mm body width, and standard 1.27 mm lead pitch - compatible with industry-standard reflow and wave soldering processes.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (1A–6A) | Schmitt-triggered inverter inputs - accept slow edges and reject noise via hysteresis; TTL-compatible at VCC ≥ 2.7 V. |
| 2, 4, 6, 8, 10, 12 | Output (1Y–6Y) | Inverted, rail-to-rail CMOS outputs - drive downstream logic or passive loads with defined VOH/VOL under load. |
| 7 | GND | Dedicated ground reference - must be low-impedance connection to minimize ground bounce and ensure threshold stability. |
| 14 | VCC | Main supply pin - powers all six inverters; decoupling capacitor (100 nF) recommended within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.0–5.5 V) | Enables single-part support across legacy 5 V and modern ultra-low-voltage (1.2 V/1.8 V) systems without redesign. |
| Input hysteresis (VH ≥ 0.3 V) | Prevents multiple toggling on noisy or slowly transitioning signals - critical for switch debouncing and sensor signal cleanup. |
| TTL input compatibility | Validates VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 2.7–3.6 V - allows direct connection to legacy microcontroller GPIO or 74-series outputs. |
| Low dynamic power (CPD = 15 pF) | Reduces switching current consumption in high-frequency oscillator or clock regeneration circuits - improves system-level efficiency. |
| −40 °C to +125 °C operation | Supports deployment in extended-temperature industrial enclosures, motor drives, and automotive non-safety ECUs. |
Applications
| Industrial Sensor Interface | Relaxation Oscillator |
|---|---|
|
Use Scenario: Converting noisy analog sensor outputs (e.g., thermistor voltage dividers or mechanical switch closures) into clean digital logic levels for MCU ADC trigger or GPIO capture. IC Role / Device Role / Timing Role: Signal conditioner and noise filter - uses Schmitt-trigger hysteresis to eliminate chatter and produce jitter-free edges. Use Value: Eliminates need for external RC filtering or firmware debouncing, reducing BOM count and improving real-time response consistency. |
Use Scenario: Generating precise, temperature-stable square-wave clocks using only one 74LV14D inverter stage plus external R/C network (Fig. 12). IC Role / Device Role / Timing Role: Astable multivibrator core - leverages input hysteresis and propagation delay to define oscillation period. Use Value: Provides low-cost, low-power clock source for microcontrollers or peripherals where crystal accuracy is unnecessary. |
| Power Sequencing Monitor | Noise-Immune Pulse Shaper |
|
Use Scenario: Monitoring delayed power rail rise times (e.g., 3.3 V after 12 V) and generating a clean "power-good" assertion signal for FPGA or SoC reset control. IC Role / Device Role / Timing Role: Threshold detector and edge shaper - converts monotonic ramp into sharp logic transition with controlled timing margin. Use Value: Ensures deterministic system startup by rejecting ripple and overshoot on power rails before releasing reset. |
Use Scenario: Cleaning up degraded digital pulses from long cables, optocouplers, or relay contacts before feeding into timing-critical logic or counters. IC Role / Device Role / Timing Role: Waveform regenerator - restores signal integrity by retiming and sharpening edges with fixed hysteresis window. Use Value: Prevents metastability and false triggering in counter/timer peripherals, especially in factory automation or test equipment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverting Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC14D,653 | Higher VCC min = 2.0 V; no 1.0–2.0 V operation; slightly higher propagation delay (25 ns typ @ 4.5 V). | Not suitable for 1.2 V or 1.8 V systems; requires ≥2.0 V supply - limits use in battery-powered IoT nodes. | Select when operating exclusively at 4.5–5.5 V and legacy HC logic compatibility is required. |
| SN74LV14APW | Same electrical specs but in TSSOP14 (SOT402-1); 4.4 mm body width; thermal resistance 130 K/W vs. SO14's 100 K/W. | Better PCB space efficiency but reduced thermal margin in high-duty-cycle oscillator use. | Select for compact layouts where board area is constrained and ambient temperature remains ≤85 °C. |
Compared with 74LV14D,118, the 74HC14D lacks ultra-low-voltage support below 2.0 V and offers less noise immunity at low VCC, while SN74LV14APW trades thermal robustness for footprint reduction - making the SO14-packaged 74LV14D optimal for cost-sensitive, thermally demanding, or mixed-voltage industrial designs.

FAQ
Is 74LV14D,118 pin-compatible with 74HC14?
Yes - the 74LV14D,118 is functionally and pin-compatible with 74HC14 and 74HCT14, sharing identical SO14 pinout and logic behavior. However, it extends supply range down to 1.0 V and offers lower input thresholds, making it suitable for mixed-voltage systems where HC devices would fail to recognize logic levels.
What is the minimum VCC required for guaranteed operation?
The 74LV14D,118 is specified to operate down to VCC = 1.0 V, with static characteristics guaranteed from 1.2 V. At 1.0 V, functionality is maintained for inputs driven to GND or VCC, though propagation delay increases and hysteresis narrows - verified per Nexperia's Rev. 10 datasheet Section 9.
Can 74LV14D,118 drive an LED directly?
Yes - with appropriate current-limiting resistor, the 74LV14D,118 can sink up to 6 mA (VOL < 0.4 V at VCC = 3.0 V) or source up to 6 mA (VOH > 2.4 V). For a typical red LED (2.0 V forward voltage), a 180 Ω resistor at 3.3 V yields ~6.7 mA - within safe operating limits and consistent with datasheet output drive specs.
Does 74LV14D,118 require external pull-up resistors on inputs?
No - inputs are CMOS with high-impedance structure and defined Schmitt thresholds; floating inputs are not permitted due to undefined state and potential increased ICC. External pull-up/down resistors are only needed for specific logic states during power-up or idle conditions, not for basic operation.
