Product details
Overview
74LVC1G08FW4-7 from Diodes Incorporated is a single 2-input positive AND gate in a 1.0 mm × 1.0 mm X2-DFN1010-6 package, operating from 1.65 V to 5.5 V with 5.5 V-tolerant inputs and ±24 mA output drive at 3.3 V. It implements the Boolean function Y = A · B and supports partial power-down via IOFF circuitry for backflow prevention in mixed-voltage systems such as USB peripheral interface logic.
For engineers reviewing the 74LVC1G08FW4-7 datasheet, 74LVC1G08FW4-7 pinout, 74LVC1G08FW4-7 application, or 74LVC1G08FW4-7 equivalent, this device is selected for low-voltage logic level translation, power-down isolation in portable electronics, and compact board space-constrained designs requiring guaranteed 5.5 V input tolerance and rail-to-rail CMOS compatibility.
Technical Context
This device uses standard CMOS push-pull output architecture with no internal pull-ups or open-drain configuration. Its IOFF circuit actively disables the output when VCC = 0 V, blocking current flow between powered and unpowered domains - critical for hot-swap and multi-rail system integrity.
Input thresholds are voltage-ratio-based (e.g., VIH ≥ 0.65×VCC at 1.65–1.95 V), enabling reliable interfacing across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families. Propagation delay ranges from 0.5 ns (typ) at 5 V to 3.4 ns (typ) at 1.8 V, with consistent 16 pF power dissipation capacitance independent of supply voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct use across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V - allows safe connection to higher-voltage signals while powered from lower supplies (e.g., 1.8 V). |
| IOFF Leakage Current | ±10 μA max at 0 V VCC - ensures robust signal isolation during partial power-down without damaging back-current. |
| Output Drive Strength | ±24 mA at 3.3 V - sufficient to drive multiple LVC loads or small capacitive traces without buffering. |
| Propagation Delay | 0.5 ns (typ) to 8.0 ns (max) - supports >100 MHz toggle rates in 5 V systems and maintains timing predictability down to 1.65 V. |
| ESD Protection | 2 kV HBM, 1 kV CDM - exceeds JEDEC JESD22-A114/A101 requirements for handling and board-level robustness. |
| Operating Temperature | −40 °C to +125 °C - qualified for industrial and extended-temperature embedded applications. |
Pinout & Package
X2-DFN1010-6: 1.0 mm × 1.0 mm × 0.4 mm body, 0.35 mm pad pitch, 6-terminal land-grid package with exposed thermal pad (not electrically connected). Pin 1 marked by chamfered corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | First logic input; accepts 0–5.5 V regardless of VCC; internally clamped. |
| B | Data Input | Second logic input; identical electrical behavior to Pin A. |
| GND | Ground Reference | Primary return path for all internal logic and output current; must be low-impedance. |
| VCC | Power Supply | CMOS core supply; range 1.65–5.5 V; powers IOFF circuitry and output stage. |
| Y | Data Output | Push-pull CMOS output; drives high/low actively; sinks/sourcing up to ±24 mA. |
| NC | No Connection | Unbonded die pad; must remain floating and unconnected on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| IOFF Partial Power-Down Support | Prevents destructive current flow between live and unpowered subsystems during sequencing or sleep states. |
| 5.5 V-Tolerant Inputs | Eliminates need for external level translators when interfacing with legacy 5 V peripherals or mixed-supply buses. |
| Low Dynamic Power Consumption | ICC ≤ 0.1 μA typical at 3.3 V - reduces quiescent current in always-on control logic paths. |
| Small Footprint (1.0 mm × 1.0 mm) | Reduces PCB area by >70% vs. SOT25/SOT353; ideal for ultra-compact mobile and wearable designs. |
| Guaranteed Latch-Up Immunity | Exceeds 100 mA per JESD78 Class I - ensures reliability under transient overvoltage or ESD stress. |
Applications
| USB Peripheral Interface Logic | Low-Power Sensor Hub Control |
|---|---|
Use Scenario: Isolating enable signals between a 3.3 V host controller and 5 V USB transceiver during suspend/resume cycles. IC Role / Device Role / Timing Role: AND gate enabling bidirectional handshake only when both host and peripheral are active and powered. Use Value: IOFF prevents backfeed from 5 V transceiver into unpowered 3.3 V domain, eliminating risk of latch-up or data corruption. |
Use Scenario: Combining motion and ambient light sensor interrupt signals before waking an MCU from deep sleep. IC Role / Device Role / Timing Role: Glue logic performing wake-up arbitration; outputs high only when both sensors assert activity. Use Value: 1.65 V operation allows direct integration with sub-2 V sensor rails; 16 pF Cpd minimizes wake latency. |
| Industrial I/O Module Signal Conditioning | Wearable Device Power Sequencing |
Use Scenario: Validating dual-channel safety interlock signals before enabling a motor driver output stage. IC Role / Device Role / Timing Role: Safety-critical AND gate verifying redundant inputs; output drives enable pin of high-side switch. Use Value: −40 °C to +125 °C rating ensures operation in harsh environments; 2 kV HBM protects against field ESD events. |
Use Scenario: Controlling battery charger enable based on both battery presence detection and system firmware permission. IC Role / Device Role / Timing Role: Power management logic ensuring charger activates only when hardware and software conditions are met. Use Value: 0.4 mm profile fits thin-profile wearables; 5.5 V input tolerance accommodates variable battery voltage sensing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08DBVR | Same logic function and IOFF, but in SOT-23-5 (2.9 mm × 1.6 mm); 30% larger footprint; 200 mW higher θJA. | Preferred where hand-soldering or legacy layout reuse is required; less suitable for <1.2 mm² board area budgets. | Select if mechanical compatibility with existing SOT-23 footprints is mandatory and thermal margin >40 °C/W is available. |
| 74AUP1G08GW,125 | Lower ICC (0.9 μA max), wider VCC range (0.8–3.6 V), but no 5.5 V input tolerance; IOFF not specified. | Optimized for ultra-low-power sub-1 V systems (e.g., energy-harvesting nodes); incompatible with 5 V signal domains. | Select only for battery-powered sub-2 V applications where 5 V tolerance is unnecessary and standby current is critical. |
Compared with SN74LVC1G08DBVR and 74AUP1G08GW,125, the 74LVC1G08FW4-7 uniquely balances 5.5 V input tolerance, 1.0 mm² footprint, and guaranteed IOFF - making it optimal for space-constrained mixed-voltage systems requiring robust power sequencing.

FAQ
Can 74LVC1G08FW4-7 operate reliably at 1.65 V supply?
Yes. The device is fully characterized from 1.65 V to 5.5 V per its Recommended Operating Conditions. At 1.65 V, propagation delay is 8.0 ns (max), VIH is 1.07 V min, and VOL remains ≤0.45 V at 4 mA sink - meeting LVC logic thresholds for interoperability with other 1.8 V devices.
What is the function of the NC pin on the X2-DFN1010-6 package?
The NC (No Connection) pin is an unconnected die pad with no internal bond wire or circuit connection. It must remain unconnected on the PCB - neither tied to GND nor left floating with parasitic coupling. Its presence is structural, not functional, and serves package symmetry and thermal balance.
Does 74LVC1G08FW4-7 support hot-swap insertion into a live backplane?
Yes, due to its IOFF feature. When VCC = 0 V, the output is placed in high-impedance state with ±10 μA leakage, preventing current backflow from live bus lines into the unpowered device. This meets JEDEC JESD78 latch-up immunity and enables safe insertion into powered systems.
How does the 5.5 V input tolerance work without damage at VCC = 1.65 V?
Internal input protection diodes clamp excess voltage to VCC or GND, and the 5.5 V rating is validated under Absolute Maximum Ratings with current limited to ±50 mA. At 1.65 V operation, VI = 5.5 V is permissible because the input structure includes series resistance and clamping that dissipates energy safely within rated limits.
