Product details
Overview
74LVC1G14Z-7 from Diodes Incorporated is a single-channel Schmitt-trigger inverter IC in SOT553 package, operating from 1.65V to 5.5V supply, with 5.5V-tolerant inputs, ±24mA output drive at 3.3V, and IOFF partial power-down protection. It enables reliable signal conditioning and noise-immune inversion in compact portable electronics.
For engineers reviewing the 74LVC1G14Z-7 datasheet, 74LVC1G14Z-7 pinout, 74LVC1G14Z-7 application, or 74LVC1G14Z-7 equivalent, key selection criteria include hysteresis width (0.35–1.20V), propagation delay (0.7–6.5ns), input voltage tolerance, IOFF leakage (<±200µA), and thermal resistance (231°C/W) in the 1.6mm × 1.6mm SOT553 footprint.
Technical Context
This device implements a positive Boolean inverter function (Y = A̅) with Schmitt-trigger input thresholds-VT+ ranging from 0.70V (1.65V VCC) to 3.33V (5.5V VCC), and VT− from 0.30V to 2.35V-yielding hysteresis ΔVT of 0.30–1.40V for robust noise rejection. Its IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0V while inputs or outputs remain biased up to 5.5V.
Designed for mixed-voltage interfacing, it supports level shifting between 1.8V/2.5V/3.3V/5V domains without external components. The SOT553 package delivers low thermal resistance (θJA = 231°C/W) and minimal board area (1.6mm × 1.6mm), optimized for space-constrained applications requiring fast, clean edge regeneration.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
SOT553 is a 5-pin ultra-thin leadless package (1.6mm × 1.6mm × 0.62mm, 0.5mm pitch), with exposed pad for thermal enhancement and optimized solderability. Pin 1 is marked by chamfered corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input | Schmitt-trigger input accepting 0–5.5V; threshold hysteresis enables noise immunity. |
| 2 (GND) | Ground Reference | Return path for all internal logic and output current; must be low-impedance for stable operation. |
| 3 (Y) | Inverted Output | Push-pull CMOS output driving high/low with rail-to-rail swing and ±24mA capability. |
| 4 (NC) | No Connect | Internally unconnected; must be left floating or tied to GND per layout guidelines. |
| 5 (VCC) | Power Supply | Primary supply input (1.65–5.5V); decoupling capacitor required within 2mm for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65V–5.5V operation allows drop-in use across legacy and modern low-voltage systems without redesign. |
| 5.5V-Tolerant Inputs | Enables direct connection to 5V buses while powered from 1.8V/2.5V rails-eliminating external level translators. |
| IOFF Partial Power-Down | Prevents destructive current flow when VCC = 0V but I/O pins remain active-critical for hot-swap and power-gating designs. |
| Low Dynamic Power | ICC ≤200µA max at 125°C ensures minimal quiescent consumption in battery-powered always-on nodes. |
| Small Footprint | SOT553 (1.6mm × 1.6mm) reduces PCB area by >50% vs. SOT23-5, enabling ultra-compact wearables and IoT sensors. |
Applications

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 | SOT23-5 package (3.0mm × 1.75mm); higher θJA (204°C/W); identical electrical specs. | Larger footprint limits use in ultra-dense layouts; better thermal performance in low-airflow enclosures. | Select when board space permits and thermal dissipation >200mW is required. |
| 74AUP1G14GW,125 | Lower ICC (≤10µA typ), wider hysteresis (ΔVT up to 1.5V), but reduced drive (±4mA at 3.3V). | Better for battery-critical always-on sensing; insufficient for driving >10pF loads or fan-out >2. | Select only for ultra-low-power, low-speed signal conditioning where drive strength is secondary. |
Compared with SN74LVC1G14DBVR and 74AUP1G14GW,125, the 74LVC1G14Z-7 uniquely balances ultra-small size (1.6mm²), full 5.5V input tolerance, and ±24mA drive-making it optimal for space- and performance-constrained portable electronics.

FAQ
What is the maximum operating temperature for 74LVC1G14Z-7?
The 74LVC1G14Z-7 is rated for continuous operation from –40°C to +125°C ambient temperature. At +125°C, electrical parameters such as IOFF leakage (≤±200µA) and VOL (≤0.8V at 32mA) remain guaranteed per the datasheet's extended temperature characterization.
Can 74LVC1G14Z-7 be used with a 1.8V supply and 5V input signals?
Yes. The device supports VCC = 1.8V while accepting VI up to 5.5V-enabling direct interfacing between 1.8V logic domains and legacy 5V peripherals without external level-shifting components.
Is the NC pin on 74LVC1G14Z-7 required to be grounded?
No. Pin 4 is internally unconnected. Diodes Incorporated recommends leaving it floating or connecting it to GND only if required by PCB layout rules for symmetry or thermal relief-no electrical impact results from either choice.
How does IOFF functionality protect the device during partial power-down?
When VCC = 0V, the IOFF circuit disables both input and output buffers, limiting leakage current to ±200µA even if 5.5V is applied to A or Y pins-preventing damaging reverse current flow into a powered-down system section.
