Product details
Overview
74LVC1G02FW4-7 from Diodes Incorporated is a single 2-input positive NOR gate in X2-DFN1010-6 package (1.0 mm × 1.0 mm × 0.4 mm, 0.35 mm pad pitch), operating from 1.65 V to 5.5 V supply, delivering ±24 mA output drive at 3.3 V, with 5.5 V-tolerant inputs and IOFF partial-power-down protection. It performs Boolean Y = A + B and is used for voltage-level shifting and power-down signal isolation in portable logic interfaces.
For engineers reviewing the 74LVC1G02FW4-7 datasheet, 74LVC1G02FW4-7 pinout, 74LVC1G02FW4-7 application, or 74LVC1G02FW4-7 equivalent, key selection criteria include supply voltage range (1.65–5.5 V), IOFF-enabled power-down isolation, 3.3 V output drive capability (±24 mA), input voltage tolerance (up to 5.5 V), and ultra-small DFN footprint compatibility with high-density PCB layouts.
Technical Context
This device implements a standard push-pull CMOS NOR gate with fully specified operation across 1.65–5.5 V, supporting mixed-voltage interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V domains. Its IOFF circuit disables outputs during power-down to prevent back-current flow, enabling safe use in partial-power-down systems.
The logic function Y = A + B is implemented with propagation delays as low as 0.5 ns (typ.) at 3.3 V and 25 °C, and input thresholds scale with VCC (e.g., VIH = 0.7 × VCC at 4.5–5.5 V). Input clamp current rating (±50 mA) and ESD robustness (2 kV HBM, 1 kV CDM) support rugged board-level integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interface across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Output Drive | ±24 mA at VCC = 3.3 V - sufficient to drive multiple LVC/LVT inputs or small capacitive loads (<30 pF) with fast edge rates. |
| Input Voltage Tolerance | Up to 5.5 V - allows 5 V inputs to be safely applied when VCC is as low as 1.65 V, critical for mixed-supply systems. |
| IOFF Leakage | ±200 μA max at –40 °C to +125 °C - ensures negligible current flow during power-down, preventing bus contention or backfeed. |
| Propagation Delay | 0.5 ns (min) / 6.0 ns (max) at VCC = 3.3 V, TA = –40 °C to +125 °C - supports >100 MHz toggle rates in clean signal paths. |
| ESD Protection | 2 kV HBM, 1 kV CDM, 200 V MM - exceeds JEDEC JESD22 standards, reducing need for external protection in consumer-grade designs. |
| Input Capacitance | 5 pF typical - minimizes loading on driving stages and preserves signal integrity in high-speed routing. |
Pinout & Package
X2-DFN1010-6 package: 1.0 mm × 1.0 mm × 0.4 mm body, 0.35 mm pad pitch, 6-terminal land-grid array with exposed thermal pad (not electrically connected). Pin 1 marked by chamfered corner per JEDEC MO-302.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | Primary logic input; accepts 0–5.5 V regardless of VCC; internally clamped to GND/VCC rails. |
| B | Data Input | Secondary logic input; identical electrical behavior to Pin A; both inputs must be terminated to avoid floating states. |
| GND | Ground Reference | Return path for all internal currents; must be low-impedance connection to system ground plane for noise immunity. |
| VCC | Power Supply | Single supply rail (1.65–5.5 V); powers internal logic and output stage; decoupling capacitor (100 nF) required within 2 mm. |
| Y | Data Output | Push-pull CMOS output; drives high/low actively; supports fan-out of ≥10 LVC loads at 3.3 V. |
| NC | No Connection | Unbonded die pad; must remain unconnected on PCB; no solder mask opening or trace routing required. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (1.65–5.5 V) | Eliminates need for separate level translators in multi-rail systems such as USB-C PD controllers or battery-powered IoT sensors. |
| IOFF partial-power-down support | Prevents destructive back-current when VCC = 0 V while inputs or outputs remain biased, essential for hot-swap and sleep-mode isolation. |
| 5.5 V-tolerant inputs | Enables direct connection to legacy 5 V microcontrollers or FPGAs without external resistors or diodes, reducing BOM count. |
| Low dynamic power (14 pF Cpd) | Reduces switching current consumption below 100 μA at 10 MHz, extending battery life in always-on sensor nodes. |
| Ultra-small X2-DFN1010-6 footprint | Occupies only 1.0 mm² PCB area - ideal for space-constrained applications like TWS earbuds, wearables, and miniaturized industrial modules. |
Applications
| USB-C Port Controller Logic | IoT Sensor Node Power Management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G02DBVR | Same logic function and 1.65–5.5 V range, but in SOT-23-5 (2.9 mm × 1.6 mm) - 2.9× larger footprint than X2-DFN1010-6. | Limited to medium-density boards where 0.65 mm lead pitch is acceptable; lacks IOFF specification in TI's datasheet (DSM001). | Select when legacy SMT placement equipment cannot handle 0.35 mm pitch DFN or when thermal dissipation >435 °C/W is required. |
| 74AUP1G02GW,125 | Lower VCC range (0.8–3.6 V), 4 μA ICC max (vs. 200 μA for 74LVC1G02), but only ±4 mA drive at 3.3 V. | Suitable for ultra-low-power always-on monitoring, but insufficient for driving >2 LVC loads or 5 V-tolerant interfaces. | Select only for sub-μA standby power budgets where 5 V input tolerance and high drive are not required. |
Compared with SN74LVC1G02DBVR and 74AUP1G02GW,125, the 74LVC1G02FW4-7 uniquely combines 5.5 V input tolerance, IOFF protection, ±24 mA drive, and 1.0 mm² footprint - making it optimal for space- and safety-critical mixed-voltage logic isolation.

FAQ
Can 74LVC1G02FW4-7 operate reliably at 1.65 V supply?
Yes - the device is fully characterized down to 1.65 V, with guaranteed propagation delay ≤8.0 ns (at –40 °C to +85 °C) and output drive ≥±4 mA. Input thresholds scale proportionally (VIH = 0.65 × VCC), ensuring correct logic interpretation across the full voltage range.
What is the thermal performance of the X2-DFN1010-6 package?
The X2-DFN1010-6 package has θJA = 445 °C/W (typical) on a 2 oz FR-4 board with minimum recommended pads. With 100 μA ICC and 24 mA switching, junction temperature rise remains <11 °C at ambient 85 °C - well within the –40 °C to +150 °C TJ rating.
Is the NC pin on 74LVC1G02FW4-7 electrically isolated?
Yes - Pin 5 (NC) is an unconnected die pad with no internal bond wire or circuit connection. It must remain unconnected on the PCB; no solder mask opening, via, or trace is permitted, per Diodes' package outline DS32197 Rev. 11-2 page 13.
Does 74LVC1G02FW4-7 support AEC-Q100 qualification?
No - this specific orderable part is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., 74LVC1G02W5Q-7 in SOT25) with PPAP documentation and IATF 16949 manufacturing, but FW4-7 is rated for commercial/industrial use only (–40 °C to +125 °C operating range).
