Product details
Overview
74LVC2G08HD4-7 from Diodes Incorporated is a dual 2-input AND gate 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 hysteresis at 3.0V). It enables voltage-level shifting and signal isolation in space-constrained portable electronics.
For engineers reviewing the 74LVC2G08HD4-7 datasheet, 74LVC2G08HD4-7 pinout, 74LVC2G08HD4-7 application, or 74LVC2G08HD4-7 equivalent, key selection criteria include its dual-gate logic function, 1.95mm × 1.0mm DFN footprint, IOFF leakage <±10μA at VCC = 0V, Schmitt-trigger input tolerance for slow edges, and guaranteed operation across –40°C to +125°C.
Technical Context
This device implements two independent positive-logic AND functions (Y = A·B) with push-pull CMOS outputs. Each gate accepts input voltages up to 5.5V regardless of VCC, enabling robust level translation between mixed-supply domains.
The IOFF circuit actively disables outputs during power-down, limiting back-current to <±10μA when VCC = 0V and inputs/outputs biased to 5.5V. Schmitt-trigger inputs provide 100mV typical hysteresis at VCC = 3.0V, ensuring noise immunity with slow-rising/falling signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - supports single-supply operation across 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Output Drive Strength | ±24mA at VCC = 3.3V - sufficient to directly drive moderate capacitive loads or interface with standard CMOS/TTL inputs |
| IOFF Leakage Current | ±10μA max at VCC = 0V - prevents damaging backflow during partial power-down in multi-rail systems |
| Input Hysteresis | 100mV typical at VCC = 3.0V - rejects noise on slow-switching control or sensor signals without external filtering |
| Propagation Delay | 2.1ns typical at VCC = 3.3V - enables reliable timing in sub-100MHz digital control paths |
| ESD Robustness | 2000V HBM, >1000V CDM - meets industrial handling requirements without additional protection circuitry |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive modules and thermally stressed embedded controllers |
Pinout & Package
X2-DFN2010-8 package: 1.95mm × 1.0mm × 0.4mm body, 0.5mm lead pitch, exposed thermal pad, RoHS-compliant, halogen- and antimony-free "Green" construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Data Input (Gate 1) | First input of first AND gate; accepts 0–5.5V regardless of VCC; Schmitt-triggered |
| 1B | Data Input (Gate 1) | Second input of first AND gate; identical electrical behavior to 1A |
| 2Y | Data Output (Gate 2) | Push-pull output of second AND gate; driven high/low with ±24mA capability at 3.3V |
| GND | Ground Reference | Primary return path for logic and output currents; connects to exposed thermal pad |
| 2A | Data Input (Gate 2) | First input of second AND gate; electrically identical to 1A and 1B |
| 2B | Data Input (Gate 2) | Second input of second AND gate; fully compatible with 5.5V-tolerant inputs |
| 1Y | Data Output (Gate 1) | Push-pull output of first AND gate; shares same drive strength and IOFF behavior as 2Y |
| VCC | Supply Voltage | Power rail for internal logic and output stages; IOFF remains active even when VCC = 0V |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent AND gates | Two fully isolated logic functions in one 1.95mm × 1.0mm footprint - saves PCB area vs discrete gates or larger SOIC packages |
| IOFF partial power-down support | Outputs enter high-impedance state with <±10μA leakage when VCC = 0V - enables safe hot-insertion and rail sequencing |
| 5.5V-tolerant inputs | Accepts input signals up to 5.5V independent of VCC setting - eliminates need for external level shifters in mixed-voltage systems |
| Schmitt-trigger inputs | 100mV typical hysteresis at 3.0V - ensures clean switching on noisy or slow-rising control lines (e.g., reset, enable, sensor outputs) |
| Low dynamic power | 17pF typical power dissipation capacitance at 3.3V - reduces switching current and system-level EMI in battery-powered devices |
Applications
| Mobile Device Power Control | USB Interface Signal Conditioning |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G08DPWR | Same logic function and IOFF, but in 8-pin USON (2mm × 2mm), 0.5mm pitch; slightly higher θJA (330°C/W vs 313°C/W) | Larger footprint; less suitable for ultra-thin mobile PCBs requiring minimal Z-height | Select if board layout uses TI-standard USON pads or requires compatibility with existing TI-based BOMs |
| 74LVC2G08GW,125 | NXP variant in SOT363 (SC-70-6); 2.1mm × 1.25mm, 0.65mm pitch; no Schmitt inputs; IOFF leakage ±20μA max | Higher package height (1.1mm vs 0.4mm); lacks input hysteresis - requires external RC filtering for noisy environments | Choose only when legacy SOT363 placement exists and Schmitt functionality is not required |
Compared with SN74LVC2G08DPWR and 74LVC2G08GW,125, the 74LVC2G08HD4-7 offers the smallest footprint (1.95mm × 1.0mm), lowest profile (0.4mm), tightest IOFF leakage (±10μA), and integrated Schmitt inputs - making it optimal for space- and noise-sensitive portable and automotive applications.

FAQ
What is the maximum input voltage the 74LVC2G08HD4-7 can tolerate?
The device accepts input voltages up to 5.5V on all pins (1A, 1B, 2A, 2B), independent of VCC level. This allows direct interfacing with 5V signals even when powered from 1.8V or 3.3V, eliminating external level-shifting components in mixed-voltage designs.
Does the 74LVC2G08HD4-7 support hot insertion or partial power-down?
Yes - its IOFF circuit actively disables both outputs when VCC = 0V, limiting back-current to ±10μA maximum. This protects upstream drivers and downstream circuits during live insertion, rail sequencing, or standby modes in multi-power-domain systems.
How does the Schmitt-trigger input improve system reliability?
The 100mV typical hysteresis at VCC = 3.0V prevents false triggering from slow-rising/falling signals or noise on control lines (e.g., reset, enable, sensor alerts). It eliminates need for external RC filters or software debouncing, reducing BOM cost and firmware complexity.
What is the thermal performance of the X2-DFN2010-8 package?
The package has a junction-to-ambient thermal resistance (θJA) of 313°C/W when mounted on a standard FR-4 board with 2oz copper and minimum recommended pad layout. Its exposed thermal pad enhances heat dissipation, supporting continuous operation at full drive strength up to +125°C ambient.
