Product details
Overview
74LVC2G02HD4-7 from Diodes Incorporated is a dual 2-input NOR gate logic IC in X2-DFN2010-8 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V, with IOFF-enabled partial power-down protection and Schmitt-trigger inputs (100mV typical hysteresis at 3.0V). It enables voltage-level shifting and signal isolation in portable computing and consumer electronics.
For engineers reviewing the 74LVC2G02HD4-7 datasheet, 74LVC2G02HD4-7 pinout, 74LVC2G02HD4-7 application, or 74LVC2G02HD4-7 equivalent, this page delivers verified functional identity, validated DFN-8 pin mapping, confirmed dual-NOR Boolean behavior, IOFF and Schmitt-trigger design implications, and real-world use cases in power-gated subsystems.
Technical Context
This device implements two independent positive-logic NOR gates (Y = A + B) with push-pull CMOS outputs. Each gate accepts input voltages 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 reverse current flow during partial power-down sequences. Schmitt-trigger inputs provide noise immunity for slow-rising/falling signals, with hysteresis tightly specified at 100mV (typ) under 3.0V bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input NOR gate: Y = A + B (positive-logic OR-NOT) |
| Supply Voltage Range | 1.65V to 5.5V - supports single-supply operation across 1.8V, 2.5V, 3.3V, and 5V systems |
| Output Drive | ±24mA at VCC = 3.3V - sufficient to drive moderate capacitive loads or interface with legacy TTL inputs |
| IOFF Leakage | ±10μA max at VCC = 0V - ensures safe bus hold and prevents backfeed in powered-down sections |
| Input Hysteresis | 100mV typ at VCC = 3.0V - rejects noise on slow edges without external RC filtering |
| Propagation Delay | 0.6ns min / 6.2ns max at VCC = 3.3V - enables timing-critical control path use up to ~80MHz toggle rate |
| ESD Rating | 2000V HBM, >1000V CDM - exceeds JEDEC standards for board-level handling robustness |
Pinout & Package
X2-DFN2010-8 (2.0mm × 1.0mm × 0.4mm, 0.5mm pitch), thermally enhanced exposed pad (not electrically connected), RoHS-compliant, halogen- and antimony-free "Green" construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 1B | Gate 1 Inputs | Accept 0–5.5V logic levels; Schmitt-triggered for noise margin on slow transitions |
| 1Y | Gate 1 Output | Push-pull CMOS output; actively driven high/low; supports IOFF shutdown |
| GND | Ground Reference | Primary return path for all I/O and supply currents; connects to thermal pad |
| 2A, 2B | Gate 2 Inputs | Independent of Gate 1; identical electrical behavior and voltage tolerance |
| 2Y | Gate 2 Output | Electrically isolated from 1Y; enables dual independent NOR functions in one footprint |
| VCC | Power Supply | Single rail powering both gates; IOFF activates automatically when VCC = 0V |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5V) | Enables direct interfacing between 1.8V microcontrollers and 5V peripherals without level shifters |
| IOFF partial power-down | Prevents destructive back-current when VCC is off while I/O lines remain active at 3.3V/5V |
| Schmitt-trigger inputs | Eliminates need for external hysteresis components in noisy or high-impedance signal paths |
| ±24mA output drive @ 3.3V | Drives 15pF load with <6.2ns propagation delay - suitable for FPGA I/O expansion and sensor interface logic |
| Low ICC (10μA max) | Reduces quiescent power in always-on subsystems such as battery-backed real-time clocks or wake-up controllers |
Applications
| Portable Computing Power Control | USB Peripheral Interface Logic |
|---|---|
|
Use Scenario: Isolating USB VBUS detection logic during system suspend mode in notebooks and tablets. IC Role / Device Role / Timing Role: Dual NOR gate implements OR-of-VBUS-present and system-wake signals, with IOFF disabling output when main rail powers down. Use Value: Prevents backfeed into suspended 3.3V domain while maintaining clean wake-event assertion via Schmitt-triggered inputs. |
Use Scenario: Enabling/disabling USB data line termination resistors based on port enumeration status. IC Role / Device Role / Timing Role: One NOR gate generates enable signal from host-ready and cable-detect inputs; second gate provides inverted control for complementary switching. Use Value: Ensures impedance-matched signaling only during active enumeration, reducing EMI and standby current leakage. |
| Hard Disk Drive Motor Control Logic | Set-Top Box IR Receiver Signal Conditioning |
|
Use Scenario: Combining spindle lock and head-load ready signals before releasing motor driver enable. IC Role / Device Role / Timing Role: NOR gate performs active-low logic AND (via De Morgan) to assert motor-enable only when both conditions are met. Use Value: Guarantees mechanical safety interlock with sub-10ns timing margin, leveraging low propagation delay and rail-to-rail input tolerance. |
Use Scenario: Debouncing and noise rejection for 38kHz IR carrier pulses in digital TV remote receivers. IC Role / Device Role / Timing Role: Schmitt-trigger inputs clean up slow-rise IR detector output; NOR gate inverts and combines with microcontroller interrupt request. Use Value: Eliminates false triggers from ESD transients or fluorescent lighting interference without software polling overhead. |
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 |
|---|---|---|---|
| SN74LVC2G02DPWR | Same logic function and IOFF, but in 8-pin USON (1.5mm × 2.0mm), 0.5mm pitch; slightly lower θJA (290°C/W) | Requires different PCB land pattern; better thermal performance in dense layouts | Select if board space allows USON footprint and thermal dissipation is prioritized over minimal area. |
| 74AUP2G02GW,125 | Lower ICC (0.9μA typ), wider VCC range (0.8–3.6V), no IOFF; Schmitt inputs retained | Not suitable for partial-power-down systems; optimized for ultra-low-power always-on sensing nodes | Choose only for battery-powered edge sensors where VCC never drops to 0V and sub-μA quiescent current is critical. |
Compared with SN74LVC2G02DPWR and 74AUP2G02GW,125, the 74LVC2G02HD4-7 uniquely balances compact DFN2010-8 size, guaranteed IOFF behavior, and 5.5V-tolerant inputs - making it optimal for space-constrained, mixed-voltage, and power-gated consumer electronics.

FAQ
Can 74LVC2G02HD4-7 be used with 1.8V microcontrollers driving 5V peripherals?
Yes. Its inputs tolerate up to 5.5V regardless of VCC, and its 1.65–5.5V supply range allows direct connection to 1.8V logic while driving 5V-tolerant loads. The ±24mA drive at 3.3V ensures reliable fanout without external buffers.
What happens to outputs during system power-down when VCC = 0V?
The built-in IOFF circuit automatically disables both outputs, limiting leakage to ±10μA max. This prevents damaging reverse current from live I/O lines into the unpowered IC, satisfying JEDEC JESD78 latch-up immunity requirements.
Is the X2-DFN2010-8 package compatible with standard reflow profiles?
Yes. The package is rated for standard lead-free reflow (J-STD-020, peak 260°C), with thermal resistance θJA = 313°C/W on 2oz FR-4. Its 0.5mm pitch and exposed thermal pad require controlled solder paste volume and profile ramp rates to ensure void-free attachment.
How does the Schmitt-trigger input improve reliability in noisy environments?
With 100mV typical hysteresis at 3.0V, it rejects noise spikes smaller than the threshold gap, preventing multiple false toggles on slow or noisy edges - eliminating need for external RC filters in IR receivers, reset circuits, or mechanical switch debouncing.
