Product details
Overview
74LVC2G02HK3-7 from Diodes Incorporated is a dual 2-input NOR gate logic IC in X2-DFN1410-8 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V with IOFF-enabled partial power-down isolation, used for voltage level shifting and signal isolation in portable computing and consumer electronics.
For engineers reviewing the 74LVC2G02HK3-7 datasheet, 74LVC2G02HK3-7 pinout, 74LVC2G02HK3-7 application, or 74LVC2G02HK3-7 equivalent, key selection criteria include its dual-NOR function, 0.4mm pitch DFN footprint, Schmitt-trigger input hysteresis (100mV typ. at 3.0V), IOFF leakage <±10μA, and guaranteed operation from –40°C to +125°C ambient.
Technical Context
This device implements two independent positive-logic NOR gates (Y = A + B) with push-pull CMOS outputs. Each gate accepts inputs up to 5.5V regardless of VCC, enabling robust level translation across mixed-voltage domains.
The integrated IOFF circuit disables both outputs when VCC = 0V, blocking back-current flow into powered subsystems. Schmitt-trigger inputs provide 100mV typical hysteresis at VCC = 3.0V, tolerating slow-rising/falling signals without oscillation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input NOR gate (Y = A + B); enables compact discrete logic replacement in space-constrained designs |
| Supply Voltage Range | 1.65V to 5.5V; supports direct interface with 1.8V, 2.5V, 3.3V, and 5V systems without level shifters |
| Output Drive | ±24mA at VCC = 3.3V; sufficient to drive multiple LVC loads or small capacitive buses (≤30pF) |
| IOFF Leakage | ±10μA max at TA = –40°C to +125°C; ensures safe isolation during partial power-down sequences |
| Propagation Delay | 0.6ns min / 6.2ns max at VCC = 3.3V; meets timing requirements for sub-100MHz control logic paths |
| Input Hysteresis | 100mV typical at VCC = 3.0V; eliminates noise-induced glitches on slow-switching control lines |
| ESD Robustness | 2000V HBM, >1000V CDM; withstands handling and board-level ESD events in consumer assembly environments |
Pinout & Package
X2-DFN1410-8 package: 1.35mm × 1.0mm × 0.35mm body, 0.4mm lead pitch, bottom thermal pad, moisture sensitivity level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 1B, 2A, 2B | Input | Four independent logic inputs; each accepts 0–5.5V, compatible with TTL and CMOS thresholds |
| 1Y, 2Y | Output | Push-pull CMOS outputs; actively driven high/low; support bus-hold or external pull-up/down |
| VCC | Supply | Single positive supply pin; powers both gates and internal bias networks |
| GND | Reference | Ground return for all logic and output current paths; must be low-impedance for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5V) | Enables single part number across 1.8V/2.5V/3.3V/5V system rails without redesign or voltage translation |
| IOFF partial power-down | Prevents damaging back-current flow when VCC is off while other system rails remain active |
| Schmitt-trigger inputs | Eliminates need for external RC filtering on noisy or slow-rising control signals (e.g., mechanical switches) |
| ±24mA output drive @ 3.3V | Drives ≥10 LVC loads or 30pF trace capacitance without external buffering in compact PCB layouts |
| Halogen- and antimony-free "Green" | Meets strict environmental compliance (Br+Cl <1500ppm, Sb <1000ppm) for global consumer product certifications |
Applications
| Power Down Signal Isolation | Voltage Level Shifting |
|---|---|
|
Use Scenario: Isolating enable/disable signals between powered and unpowered subsystems in laptops during sleep mode. IC Role / Device Role / Timing Role: Dual NOR gate acts as bidirectional signal blocker; IOFF prevents backfeed when main VCC is removed. Use Value: Eliminates risk of latch-up or current injection into powered peripherals during partial shutdown sequences. |
Use Scenario: Translating 1.8V GPIO outputs from an MCU to control 3.3V peripherals in tablet I/O expansion. IC Role / Device Role / Timing Role: NOR gate configured as inverter with level-tolerant inputs; operates natively across both voltage domains. Use Value: Removes need for dedicated level translators, reducing BOM count and PCB area in battery-powered devices. |
| General Purpose Logic | PC Peripheral Control |
|
Use Scenario: Implementing simple combinatorial logic (e.g., reset arbitration, status flag merging) in USB-C dock firmware. IC Role / Device Role / Timing Role: Dual gate provides two independent logic functions; propagation delay ≤6.2ns ensures deterministic timing at 50MHz control rates. Use Value: Replaces discrete transistor logic or larger 14-pin packages, saving >70% board space in ultra-thin enclosures. |
Use Scenario: Managing hot-plug detection and power sequencing for SD card slots and USB hubs in notebook motherboards. IC Role / Device Role / Timing Role: NOR gate performs OR-inverted logic for fault signaling; Schmitt inputs reject contact bounce from card insertion events. Use Value: Improves system reliability by eliminating false interrupts caused by mechanical switch transients in high-volume consumer platforms. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G02DCKR | Same logic function and IOFF, but in SC70-8 (2.0mm × 1.25mm); 0.65mm pitch; higher θJA (390°C/W) | Larger footprint and lower thermal performance; less suitable for ultra-dense portable PCBs | Choose if legacy SC70 layout reuse is required and thermal margin exceeds 25°C |
| 74AUP2G02GW,125 | Lower ICC (0.9μA typ.), wider VCC (0.8–3.6V), but no IOFF; max output drive ±4mA at 3.0V | Not suitable for partial power-down isolation; limited to low-power always-on domains | Prefer only where ultra-low static power dominates over signal integrity and isolation needs |
Compared with SN74LVC2G02DCKR and 74AUP2G02GW,125, the 74LVC2G02HK3-7 uniquely balances ultra-small X2-DFN1410-8 size, full 1.65–5.5V operation, robust ±24mA drive, and mandatory IOFF for modern portable electronics requiring safe multi-rail sequencing.

FAQ
Can 74LVC2G02HK3-7 operate with 1.65V supply and still meet timing specs?
Yes. The device is fully characterized down to 1.65V: propagation delay is 8.9ns max at –40°C to +85°C and 11.2ns max across –40°C to +125°C. Input thresholds scale with VCC (VIH = 0.65×VCC), ensuring reliable switching even at minimum supply.
Does the X2-DFN1410-8 package require special PCB layout considerations?
Yes. The 0.4mm pitch and exposed thermal pad demand precise stencil design (0.12mm thickness, 1:1 aperture ratio) and reflow profile control. Recommended pad layout matches Diodes' outline drawing: 0.35mm × 0.60mm solder pads with 0.20mm solder mask opening, plus centered 0.8mm × 0.8mm thermal pad with 4×0.3mm thermal vias.
How does IOFF behave when VCC = 0V but inputs are pulled to 3.3V?
IOFF activates automatically when VCC drops below ~0.8V, disabling both outputs and limiting leakage to ±10μA max across temperature. This prevents current from flowing from 3.3V inputs into the unpowered VCC rail, protecting upstream drivers and avoiding unintended logic states.
Is the Schmitt-trigger hysteresis adjustable or fixed?
Fixed and process-trimmed: hysteresis is 100mV typical at VCC = 3.0V, with no external adjustment. It scales approximately linearly with VCC-e.g., ~75mV at 2.3V and ~125mV at 3.6V-ensuring consistent noise immunity across the full operating range.
