Product details
Overview
74LVC2G08RA3-7 from Diodes Incorporated is a dual 2-input AND gate in X2-DFN1210-8 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V, with IOFF-enabled partial power-down isolation and Schmitt-trigger inputs (100mV hysteresis at 3.0V). It enables voltage-level shifting and signal gating in space-constrained portable electronics.
For engineers reviewing the 74LVC2G08RA3-7 datasheet, 74LVC2G08RA3-7 pinout, 74LVC2G08RA3-7 application, or 74LVC2G08RA3-7 equivalent, key selection criteria include its 1.2mm × 1.0mm DFN footprint, IOFF leakage <±20μA at 5.5V, 4.7ns typical propagation delay at 3.3V, and 2.5pF input capacitance - all critical for low-power, high-density logic interfacing.
Technical Context
This device implements two independent positive-logic AND functions (Y = A · B) using CMOS technology with rail-to-rail input tolerance up to 5.5V and push-pull outputs. Its IOFF circuit actively disables outputs during VCC = 0V, blocking reverse current flow between powered and unpowered system domains.
Schmitt-trigger inputs provide 100mV hysteresis at VCC = 3.0V, enabling robust operation with slow-rising/falling signals (≤20 ns/V transition rate at 1.65–2.7V), while ESD protection exceeds 2kV HBM and 1kV CDM per JESD22.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - supports single-supply interoperability across 1.8V, 2.5V, 3.3V, and 5V logic domains. |
| Output Drive Strength | ±24mA at VCC = 3.3V - drives standard CMOS loads without external buffers in I/O expansion or level-shifting paths. |
| Propagation Delay | 4.7ns typical at VCC = 3.3V - enables reliable timing in sub-100MHz digital control and interface logic. |
| IOFF Leakage Current | ±20μA max at VI/VO = 5.5V, VCC = 0V - prevents backfeed damage during hot-swap or partial power-down sequences. |
| Input Hysteresis | 100mV typical at VCC = 3.0V - rejects noise on slow edges from mechanical switches or long PCB traces. |
| Input Capacitance | 2.5pF at VCC = 3.3V - minimizes loading on preceding drivers in high-speed or low-power signal chains. |
| ESD Protection | 2000V HBM, >1000V CDM - meets industrial-grade robustness requirements without external TVS diodes. |
Pinout & Package
X2-DFN1210-8 package: 1.2mm × 1.0mm × 0.35mm body, 0.3mm lead pitch, exposed thermal pad (pin #4 GND), compliant with IPC-7351B LCC-8 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input A of Gate 1 | CMOS-compatible input accepting 0–5.5V; Schmitt-triggered for noise immunity. |
| 1B | Input B of Gate 1 | Independent logic input; tied to 1A for NAND/NOR emulation via external inversion. |
| 2Y | Output Y of Gate 2 | Push-pull output capable of sourcing/sinking ±24mA at 3.3V; IOFF active when VCC = 0V. |
| GND | Ground Reference | Primary return path and thermal pad connection; must be soldered for thermal performance (θJA = 395°C/W). |
| 2A | Input A of Gate 2 | Second independent AND gate input; electrically isolated from Gate 1 except shared VCC/GND. |
| 2B | Input B of Gate 2 | Redundant input for dual-gate logic partitioning; supports separate signal routing on dense PCBs. |
| 1Y | Output Y of Gate 1 | Active-high AND result; compatible with TTL/CMOS fanout rules up to 10 LVC loads. |
| VCC | Supply Voltage | Single power rail for both gates; IOFF circuit monitors this node to disable outputs during power loss. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent AND gates | Two fully isolated logic functions in one 1.2mm × 1.0mm package - reduces board area vs. discrete gates or larger SOIC-8 equivalents. |
| IOFF partial power-down support | Outputs enter high-impedance state with <±20μA leakage when VCC = 0V - enables safe interconnection between live and unpowered subsystems. |
| Schmitt-trigger inputs | 100mV hysteresis at 3.0V eliminates contact bounce or EMI-induced glitches on slow-switching signals like reset or enable lines. |
| Rail-to-rail input tolerance | Accepts 0–5.5V inputs regardless of VCC setting - simplifies level translation between mixed-voltage domains without external resistors. |
| Low dynamic power | 17pF typical power dissipation capacitance at 10MHz - cuts switching power by >50% versus older LVT logic families at same speed. |
Applications
| USB Peripheral Interface | Mobile Device Power Sequencing |
|---|---|
|
Use Scenario: Enabling USB data line drivers only after VBUS detection and PHY initialization. IC Role / Device Role / Timing Role: Dual AND gate performs synchronized enable gating: one gate validates VBUS + READY signal; second gate controls driver EN pin. Use Value: Prevents spurious USB enumeration by ensuring drivers activate only when both power and firmware readiness are confirmed. |
Use Scenario: Coordinating power-up sequence of RF transceiver, sensor hub, and application processor in smartphones. IC Role / Device Role / Timing Role: Each AND gate combines reset assertion and voltage monitor outputs to generate domain-specific power-good signals. Use Value: Eliminates need for dedicated power sequencer IC by implementing custom timing logic with <10ns skew between gated outputs. |
| Industrial Sensor Node Logic | Wearable Device Button Debounce |
|
Use Scenario: Isolating analog sensor outputs from MCU during deep-sleep mode to reduce system leakage. IC Role / Device Role / Timing Role: One AND gate passes sensor data only when MCU_WAKE# is active; second gate enables ADC clock only during sampling windows. Use Value: Reduces average current by 12μA per gated path via IOFF shutdown - extends battery life in multi-year deployments. |
Use Scenario: Cleaning mechanical switch inputs before feeding to low-power microcontroller GPIOs. IC Role / Device Role / Timing Role: Schmitt-trigger inputs condition noisy button signals; AND logic ensures only stable high/low states reach the MCU interrupt pin. Use Value: Achieves <1ms debounce without software timers or RC networks - preserves MCU sleep cycles and simplifies firmware. |
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 (1.5mm × 1.5mm) package with 0.5mm pitch - 25% larger footprint, higher θJA (340°C/W). | Less suitable for ultra-dense wearables due to larger size; preferred where rework accessibility matters. | Select when board assembly uses standard USON tooling and thermal margin >30°C is available. |
| 74AUP2G08GW,125 | Lower ICC (0.9μA max) and smaller 6-pin XSON (1.0mm × 1.0mm), but no IOFF and narrower 0.8–3.6V supply range. | Not usable in partial-power-down systems; limited to always-on 1.8V/2.5V domains like sensor front-ends. | Choose only for battery-critical always-on nodes where power-down isolation is unnecessary. |
Compared with SN74LVC2G08DPWR and 74AUP2G08GW,125, the 74LVC2G08RA3-7 uniquely balances ultra-small 1.2mm × 1.0mm size, full 1.65–5.5V operation, and robust IOFF protection - making it the sole option for miniaturized, mixed-voltage, hot-pluggable designs.

FAQ
Can 74LVC2G08RA3-7 operate with 1.65V supply while interfacing with 5V inputs?
Yes. The device accepts input voltages up to 5.5V regardless of VCC setting, enabling direct connection to 5V signals even at minimum 1.65V supply. This eliminates level-shifters in mixed-voltage systems, provided output loads are compatible with 1.65V logic levels.
What is the thermal impact of using the X2-DFN1210-8 package without soldering the exposed pad?
Omitting thermal pad soldering increases junction-to-ambient thermal resistance from 395°C/W to >500°C/W, risking thermal shutdown above 15mA continuous output current at +85°C ambient. Diodes Incorporated's recommended pad layout requires full GND pad connection for rated performance.
How does the IOFF feature behave when VCC is ramping during power-up?
IOFF activates only when VCC falls below ~0.8V - during power-up, outputs remain functional once VCC exceeds 1.0V. No special power sequencing is required; the gate operates normally through the entire 1.65–5.5V range and transitions cleanly into IOFF only during full power loss.
Is the Schmitt-trigger hysteresis adjustable or fixed?
Hysteresis is fixed at approximately 100mV at VCC = 3.0V and scales proportionally with supply voltage (e.g., ~70mV at 2.5V). It is not user-adjustable but provides consistent noise margin across the full 1.65–5.5V operating range without external components.
