Product details
Overview
74LVC1G32FZ4-7 from Diodes Incorporated is a single 2-input positive OR gate in X2-DFN1410-6 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 circuitry and enables voltage-level shifting in mixed-voltage digital interfaces such as USB peripheral logic control and I²C bus signal conditioning.
For engineers reviewing the 74LVC1G32FZ4-7 datasheet, 74LVC1G32FZ4-7 pinout, 74LVC1G32FZ4-7 application, or 74LVC1G32FZ4-7 equivalent, key selection criteria include IOFF-enabled power-down isolation, 0.5mm pitch DFN footprint compatibility, propagation delay ≤4.5ns at 3.3V, and 5.5V input tolerance for interfacing with legacy 5V logic domains.
Technical Context
This device implements a non-inverting Boolean OR function (Y = A + B) using CMOS technology with push-pull output stage. Its IOFF circuit actively disables output leakage during VCC = 0V, preventing back-current flow in powered-down subsystems.
Input thresholds scale with VCC (e.g., VIH ≥ 0.7×VCC at 4.5–5.5V), and output drive strength is specified across full 1.65–5.5V range - delivering –24mA/24mA at 3V and –32mA/32mA at 4.5V - enabling direct TTL-level interfacing without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - supports operation across 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Input Voltage Tolerance | Up to 5.5V - allows safe connection to higher-voltage signals without clamping diodes |
| Output Drive Strength | ±24mA at VCC = 3.3V - sufficient to drive multiple LVC/LVT inputs or small capacitive loads |
| Propagation Delay | ≤4.5ns (max) at VCC = 3.3V - ensures timing compliance in sub-10ns logic paths |
| IOFF Leakage Current | ±200μA max at TA = –40°C to +125°C - maintains signal integrity during partial power-down |
| ESD Protection | HBM >2000V, CDM >1000V - exceeds JEDEC JESD22-A114/A101 for board-level robustness |
| Operating Temperature | –40°C to +125°C - qualified for industrial and extended-temperature embedded applications |
Pinout & Package
X2-DFN1410-6 is a 1.4mm × 1.0mm × 0.4mm leadless surface-mount package with 0.5mm pad pitch and exposed thermal pad (non-electrical). Pin 1 identification is marked by a chamfered corner on top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | First OR gate input; accepts 0–5.5V logic levels independent of VCC |
| B | Data Input | Second OR gate input; fully 5.5V tolerant with no external protection required |
| Y | Data Output | Push-pull CMOS output; drives high/low actively; sinks/sourcing up to ±24mA at 3.3V |
| VCC | Supply Voltage | Primary power rail; must be decoupled locally; supports 1.65–5.5V operation |
| GND | Ground Reference | Return path for all currents; connects to PCB ground plane under thermal pad |
| NC | No Connection | Unbonded die pad; electrically isolated; must not be connected to any net |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65–5.5V operation enables drop-in use across 1.8V, 2.5V, 3.3V, and 5V systems |
| IOFF Partial Power-Down | Output automatically high-impedance when VCC = 0V, preventing backfeed into powered-down rails |
| 5.5V-Tolerant Inputs | Accepts 5V signals while powered from 1.8V or 2.5V - eliminates need for discrete level shifters |
| Low Dynamic Power | ICC ≤ 200μA at 5.5V - reduces quiescent current in always-on logic monitoring circuits |
| Small Footprint | 1.4mm × 1.0mm X2-DFN1410-6 saves >60% board area vs. SOT25 and supports high-density routing |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G32DBVR | SOT-23-5 package (3.0×2.8mm); higher θJA (204°C/W); no NC pin; same electrical specs | Less space-constrained designs where manual rework or test probing is needed | Select when board layout allows larger footprint and thermal management uses standard SOT-23 pads |
| 74LVC1G32FS3-7 | X2-DFN0808-4 (0.8×0.8mm); 4-pin, no NC; requires different PCB layout and solder stencil | Ultra-dense portable electronics where 0.8mm² footprint is mandatory | Choose only if size reduction outweighs need for NC pin and reduced thermal performance (θJA = 400°C/W) |
Compared with SN74LVC1G32DBVR and 74LVC1G32FS3-7, the 74LVC1G32FZ4-7 provides optimal balance of compact size (1.4×1.0mm), thermal performance (θJA = 460°C/W), and design flexibility via the NC pin for future routing or grounding options.

FAQ
What is the maximum allowable input voltage when VCC = 1.8V?
The 74LVC1G32FZ4-7 supports input voltages up to 5.5V regardless of VCC level. When VCC = 1.8V, inputs A and B may safely accept 0–5.5V signals without damage or functional degradation, enabling direct connection to 5V peripherals in mixed-voltage systems.
Does the NC pin require PCB connection or grounding?
No. The NC (No Connection) pin on the X2-DFN1410-6 package is an unconnected die pad with no internal bond wire. It must remain electrically floating - neither connected to GND nor any other net - to avoid unintended coupling or thermal stress.
Can this device be used in partial-power-down mode with VCC = 0V?
Yes. The integrated IOFF circuit disables the output stage when VCC drops below ~0.8V, placing Y in high-impedance state. This prevents reverse current flow from live inputs (e.g., 5.5V signals) into the unpowered VCC rail, satisfying JEDEC JESD76 requirements.
What is the recommended PCB pad layout for X2-DFN1410-6?
Use Diodes' documented footprint: 0.25mm × 0.525mm solder pads (6 total), 0.5mm center-to-center spacing, with a 1.25mm × 1.25mm thermal pad (non-plated) centered beneath the package. Avoid solder mask defined (SMD) pads; use non-solder-mask-defined (NSMD) for reliable reflow wetting.
