Product details
Overview
74LVC3G14V8-7 from Diodes Incorporated is a triple Schmitt-trigger inverter IC in VSSOP-8 package, operating from 1.65V to 5.5V supply, with 5.5V-tolerant inputs and ±24mA output drive at 3.3V. It supports partial power-down via IOFF, enables voltage-level shifting in mixed-voltage systems, and is used for signal conditioning in portable electronics and interface isolation.
For engineers reviewing the 74LVC3G14V8-7 datasheet, 74LVC3G14V8-7 pinout, 74LVC3G14V8-7 application, or 74LVC3G14V8-7 equivalent, this device is selected for robust noise immunity (ΔVT ≥0.3V), low ICC (≤10μA), fast propagation delay (tPD ≤5.9ns at 3.3V), and compatibility with 1.8V/2.5V/3.3V/5V logic domains.
Technical Context
This device implements three independent Schmitt-trigger inverters with hysteresis (ΔVT = 0.3–1.4V depending on VCC), enabling reliable signal reconstruction from slow or noisy inputs. Each channel performs Y = NOT(A) with rail-to-rail CMOS outputs and input thresholds VT+ (0.7–3.7V) and VT− (0.3–2.5V) that scale with supply voltage.
The IOFF circuit actively disables outputs during power-down, blocking back-current flow when VCC = 0V while inputs or outputs remain biased up to 5.5V. Input clamp current rating (±50mA) and ESD protection (2kV HBM, 1kV CDM) support robust board-level handling and hot-swap operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - Enables direct interfacing across 1.8V, 2.5V, 3.3V, and 5V logic families without level shifters. |
| Input Voltage Tolerance | Up to 5.5V - Allows safe connection of higher-voltage signals to lower-VCC logic domains (e.g., 5V sensor to 3.3V MCU). |
| Hysteresis (ΔVT) | 0.3V to 1.4V - Provides noise margin against ringing or slow-edge signals, critical for debouncing switches or recovering clock-like waveforms. |
| Output Drive Strength | ±24mA at 3.3V - Sufficient to drive multiple LVC loads or small capacitive traces without external buffers. |
| Propagation Delay (tPD) | 2.3ns (min) to 5.9ns (max) at 3.3V - Supports >100MHz signal conditioning in timing-critical paths like reset synchronization. |
| IOFF Leakage Current | ±10μA max at 125°C - Ensures negligible current flow during partial power-down, preventing bus contention in multi-rail systems. |
| ESD Protection | 2kV HBM, 1kV CDM - Meets industrial handling requirements without additional protection circuitry. |
Pinout & Package
VSSOP-8 (Very Small Outline Package, 8-pin) with 0.5mm lead pitch, 2.0mm × 3.4mm body size, and 0.35mm nominal lead length. RoHS-compliant, halogen-free, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Data Input (Inverter 1) | Accepts 5.5V-tolerant logic signal; triggers Schmitt response based on VT+/VT− thresholds. |
| 3Y | Data Output (Inverter 3) | CMOS push-pull output with ±24mA drive; active during normal operation and disabled by IOFF when VCC = 0. |
| 2A | Data Input (Inverter 2) | Independent input with identical Schmitt characteristics as 1A and 3A; no internal coupling. |
| GND | Ground Reference | Return path for all three inverters; must be low-impedance to maintain noise immunity and output swing integrity. |
| 2Y | Data Output (Inverter 2) | Electrically isolated output node; shares VCC/GND but has no crosstalk-induced switching noise with other channels. |
| 3A | Data Input (Inverter 3) | Third independent Schmitt input; supports asynchronous signal conditioning without shared timing constraints. |
| 1Y | Data Output (Inverter 1) | Primary output for first inverter channel; compatible with standard LVC load capacitance (≤50pF) and drive strength. |
| VCC | Supply Voltage | Single supply input powering all three inverters; IOFF activation occurs automatically when VCC drops below threshold. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger hysteresis | Guaranteed ΔVT ≥0.3V across full VCC range ensures reliable edge detection on slow or noisy signals (e.g., mechanical switch inputs). |
| IOFF partial power-down | Automatically disables outputs and blocks back-current when VCC = 0V, enabling safe hot-insertion in multi-supply systems. |
| 5.5V-tolerant inputs | Permits direct connection of legacy 5V peripherals to modern low-voltage controllers without external resistors or translators. |
| Low ICC (≤10μA) | Reduces quiescent power in always-on monitoring circuits, such as battery-backed reset supervisors or wake-up signal conditioners. |
| ±24mA output drive | Drives up to 10 LVC1G04 loads or 30pF trace capacitance at 3.3V, eliminating need for buffer stages in compact PCB layouts. |
Applications
| USB Peripheral Interface | Industrial Sensor Signal Conditioning |
|---|---|
|
Use Scenario: Level-shifting and noise filtering between 5V USB PHY and 3.3V microcontroller GPIO. IC Role / Device Role / Timing Role: Schmitt inverter acts as bidirectional signal conditioner for USB ID, VBUS detect, or overcurrent alert lines.

Use Scenario: Debouncing mechanical limit switches and converting slow analog comparator outputs into clean digital logic. IC Role / Device Role / Timing Role: Inverter provides hysteresis-based noise rejection and logic inversion for PLC input modules and motor control feedback. Use Value: ΔVT ≥0.4V at 2.3V supply rejects >100mV of EMI-induced noise on long sensor cables without software polling overhead. |
| Portable Device Power Sequencing | Embedded Display Backlight Control |
|
Use Scenario: Isolating enable signals during partial power-down of SoC subsystems (e.g., GPU off while CPU remains active). IC Role / Device Role / Timing Role: IOFF-enabled inverter gates power-enable lines to prevent backfeed from powered rails into unpowered domains. Use Value: IOFF leakage ≤10μA at 125°C avoids unintended turn-on of PMICs or LDOs during sleep states, extending battery life. |
Use Scenario: Inverting PWM dimming signals from 3.3V display controller to drive high-side LED current sinks requiring active-low enable. IC Role / Device Role / Timing Role: Fast tPD ≤4.7ns at 5V ensures minimal phase shift between controller PWM and LED current switching. Use Value: ±32mA drive at 4.5V directly controls gate of 2N7002-class MOSFETs without gate driver ICs, reducing BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G14DCUR | SSOP-8 package (larger footprint, 0.65mm pitch); identical electrical specs and pinout mapping. | Preferred where reflow process favors larger pitch or existing SSOP-8 land patterns exist. | Select when board assembly uses standard SSOP tooling or thermal budget allows higher ϴJA (130°C/W vs. 155°C/W). |
| 74LVC1G14GV,125 | Single-channel version in SC-70-5; no functional equivalence for triple-channel requirement. | Only suitable if design requires only one inverter and space-constrained layout permits three separate devices. | Use only when channel count can be increased via duplication and board area allows three discrete placements. |
Compared with SN74LVC3G14DCUR, the 74LVC3G14V8-7 offers 25% smaller PCB footprint and better thermal performance in dense layouts; compared with 74LVC1G14GV,125, it delivers three independent channels in one die, reducing routing complexity and inter-device skew.

FAQ
Can 74LVC3G14V8-7 operate with a 1.65V supply and still drive a 50pF load?
Yes. At VCC = 1.65V, the device guarantees tPD ≤9.7ns and VOL ≤0.45V with IOL = 4mA, sufficient to drive 50pF loads within typical microcontroller timing budgets. The CPD specification (17pF typ at 1.8V) confirms low dynamic power consumption under these conditions.
Does IOFF activate automatically when VCC is disconnected?
Yes. IOFF is an intrinsic circuit feature that activates when VCC falls below ~0.8V, disabling all three outputs and limiting leakage to ±10μA maximum at 125°C. No external control signal or bias is required-activation is fully internal and voltage-threshold-based.
What is the maximum input frequency this device can reliably condition?
While not rated as a clock buffer, the 74LVC3G14V8-7 supports clean inversion of signals up to ~100MHz under typical conditions (3.3V, 30pF load), based on tPD ≤5.9ns and rise/fall times <3ns. For sustained high-frequency use, ensure input slew rate exceeds 0.5V/ns to avoid metastability near VT thresholds.
Is the VSSOP-8 package compatible with standard reflow profiles?
Yes. The VSSOP-8 package is rated for moisture sensitivity level 1 (MSL-1) per J-STD-020 and supports standard Pb-free reflow profiles with peak temperature ≤260°C. Its 0.5mm pitch and 0.35mm lead length are compatible with Type 3 solder paste and 25–30μm stencil apertures.
