Product details
Overview
74LV14DB,112 from Nexperia is a low-voltage CMOS hex inverting Schmitt trigger IC with six independent channels, operating from 1.0 V to 5.5 V supply, delivering sharp edge regeneration for noisy inputs, and specified for -40 °C to +125 °C industrial temperature range. It provides input hysteresis (VH up to 1.5 V at VCC = 5.5 V), 13 ns typical propagation delay at 3.3 V/15 pF, and TTL-level compatibility at 2.7–3.6 V.
For engineers reviewing the 74LV14DB,112 datasheet, 74LV14DB,112 pinout, 74LV14DB,112 application, or 74LV14DB,112 equivalent, this device serves as a robust signal conditioning solution for waveform shaping, oscillator circuits, and noise-immune digital interfacing in mixed-voltage embedded systems.
Technical Context
The 74LV14DB,112 implements six independent Schmitt-trigger inverters with asymmetric switching thresholds (VT+ and VT−) enabling reliable noise rejection on slow-rising/falling signals. Its CMOS architecture ensures low static current (≤40 μA at 5.5 V) and rail-to-rail output swing capability.
It supports dual-voltage system interfacing via TTL-compatible input thresholds at VCC = 2.7–3.6 V and operates across three distinct voltage domains: ultra-low (1.0–1.95 V per JESD8-7), mid-range (2.3–2.7 V per JESD8-5), and standard (2.7–3.6 V per JESD8C and 4.5–5.5 V per JESD36).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 5.5 V - enables direct integration into 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters |
| Propagation Delay (tpd) | 13 ns typical at VCC = 3.3 V, CL = 15 pF - ensures timing predictability in clockless relaxation oscillators and debounce circuits |
| Hysteresis Voltage (VH) | 0.3 V min to 1.5 V max across VCC range - guarantees ≥300 mV noise margin against EMI in industrial sensor interfaces |
| Input Thresholds (VT+, VT−) | VT+ = 2.8 V, VT− = 2.2 V typical at VCC = 3.0 V - defines precise switching windows for stable multivibrator operation |
| Output Drive Strength | ±6 mA at VCC = 3.0 V - sufficient to directly drive multiple 74LVC inputs or small capacitive loads (<30 pF) |
| Static Supply Current (ICC) | ≤40 μA at VCC = 5.5 V, Tamb = +125 °C - supports always-on monitoring nodes in battery-backed systems |
| ESD Robustness | HBM >2000 V, CDM >1000 V - eliminates need for external protection in board-level ESD zones |
Pinout & Package
74LV14DB,112 is supplied in SSOP14 (SOT337-1) package - plastic shrink small outline package, 14 leads, body width 5.3 mm, pitch 0.65 mm - optimized for high-density PCB layouts with improved thermal performance over SO14.
| Pin/Terminal | 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 |
| 2, 4, 6, 8, 10, 12 | Output (1Y–6Y) | Inverted, jitter-free digital outputs; rail-to-rail swing with defined VOH/VOL under load |
| 7 | GND | Digital ground reference; must be low-impedance for stable hysteresis and noise immunity |
| 14 | VCC | Primary power supply; decoupling capacitor (100 nF) required within 5 mm for clean switching |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.0–5.5 V) | Enables single-part support across legacy 5 V, modern 3.3 V/2.5 V, and ultra-low-power 1.2 V/1.8 V subsystems |
| TTL input compatibility (2.7–3.6 V) | Allows direct connection to legacy microcontroller GPIOs or 74LS outputs without translation circuitry |
| Input hysteresis (VH) | Guarantees ≥0.6 V minimum hysteresis at VCC = 2.0 V, preventing chatter during slow analog-to-digital transitions |
| Low ICC at high temperature | ≤40 μA at +125 °C ensures stable operation in automotive under-hood or industrial motor-control environments |
| JEDEC-compliant ESD ratings | HBM >2000 V and CDM >1000 V meet IEC 61000-4-2 Level 3 requirements without added protection components |
Applications
| Waveform Shaping | Astable Multivibrator |
|---|---|
Use Scenario: Converting noisy sine-wave or triangle-wave sensor outputs (e.g., from hall-effect or inductive proximity sensors) into clean square waves for MCU capture timers. IC Role / Device Role / Timing Role: Signal conditioner that transforms slow, distorted edges into monotonic, jitter-free logic transitions using Schmitt-trigger hysteresis. Use Value: Eliminates false triggering in timing-critical position sensing, achieving sub-microsecond edge repeatability even with 100 mV pk-pk noise. | Use Scenario: Generating fixed-frequency clock signals for LED flashers, status indicators, or low-speed data strobes in cost-sensitive consumer electronics. IC Role / Device Role / Timing Role: Core oscillator element configured with external R-C network; one inverter stage provides feedback, another buffers output. Use Value: Delivers stable 1–100 kHz oscillation without crystals or dedicated timer ICs, reducing BOM count by two components. |
| Monostable Multivibrator | Noise-Immune Switch Debounce |
Use Scenario: Creating precise pulse-width-controlled triggers for power MOSFET gate drivers or solenoid actuation in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Edge-triggered one-shot generator where input pulse initiates fixed-duration output via RC time constant and internal inverter delay. Use Value: Achieves ±5% pulse width accuracy over -40 °C to +125 °C using only passive components, avoiding microcontroller-based timing drift. | Use Scenario: Cleaning mechanical switch bounce from pushbuttons, rotary encoders, or limit switches in factory HMI panels and medical device controls. IC Role / Device Role / Timing Role: Input filter that rejects transients <100 ns while preserving intentional user actuation edges via hysteresis threshold separation. Use Value: Guarantees single, deterministic logic transition per press-verified to 1 million cycles-without firmware polling or interrupt debouncing overhead. |
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 1.0–1.95 V operation; 20 ns tpd at 4.5 V; lower hysteresis (0.45 V typ at 4.5 V) | Not suitable for 1.2 V/1.8 V systems; requires higher supply for same speed; less noise margin in sub-2.5 V designs | Select when operating exclusively at ≥2.0 V and legacy 74HC footprint compatibility is mandatory |
| SN74LV14APWR | Same electrical specs; TSSOP14 (SOT402-1) package; 0.65 mm pitch; 4.4 mm body width | Offers superior thermal resistance (7.3 mW/K derating above 81 °C) and smaller PCB footprint than SSOP14 | Select for space-constrained, thermally demanding applications where reflow profile supports fine-pitch TSSOP |
Compared with 74HC14D,653, the 74LV14DB,112 delivers usable operation down to 1.0 V and tighter hysteresis control for low-voltage noise immunity; compared with SN74LV14APWR, it uses SSOP14 for easier hand-soldering and legacy board compatibility but trades off thermal efficiency.

FAQ
What is the maximum recommended operating frequency for 74LV14DB,112?
The 74LV14DB,112 does not specify a maximum clock frequency, as it is not a synchronous device. Its usable edge rate is governed by propagation delay (13 ns typical at 3.3 V) and input rise/fall time limits (≤2.5 ns per test conditions). For reliable Schmitt-trigger operation with clean output edges, input transitions should remain slower than 10 MHz equivalent edge rate to avoid metastability near thresholds.
Can 74LV14DB,112 drive a 50 pF load at 3.3 V while maintaining VOH ≥ 2.7 V?
Yes. At VCC = 3.3 V and IO = –6 mA (equivalent to ~50 pF at 10 MHz), VOH is guaranteed ≥2.4 V (min) and typically 2.82 V. With 15 pF load and 3.3 V supply, VOH exceeds 2.7 V under all operating temperatures (–40 °C to +125 °C), satisfying standard LVTTL high-level input requirements.
Is the SSOP14 package of 74LV14DB,112 RoHS compliant and lead-free?
Yes. The 74LV14DB,112 in SOT337-1 (SSOP14) package is manufactured per Nexperia's standard RoHS-compliant, lead-free process. It meets EU Directive 2011/65/EU and JEDEC J-STD-609 Category 3 marking requirements, with homogeneous lead content <1000 ppm and no exemptions applied.
Does 74LV14DB,112 require external pull-up or pull-down resistors on unused inputs?
No. Unused inputs must be terminated to VCC or GND to prevent floating states that increase ICC and cause erratic output switching. Internal input structure does not include weak pull-ups/pull-downs; therefore, a 10 kΩ resistor to VCC or GND is recommended for each unconnected input to ensure defined logic levels and minimize power consumption.
