Product details
Overview
74LVC1G02W5-7 from Diodes Incorporated is a single 2-input positive NOR gate in SOT25 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V, with 5.5V-tolerant inputs and IOFF partial-power-down protection. It performs the Boolean function Y = A + B and is used for voltage-level shifting and signal isolation in portable logic interfaces.
For engineers reviewing the 74LVC1G02W5-7 datasheet, 74LVC1G02W5-7 pinout, 74LVC1G02W5-7 application, or 74LVC1G02W5-7 equivalent, key selection criteria include supply voltage flexibility (1.65–5.5V), 5.5V input tolerance in mixed-voltage systems, IOFF-enabled power-down safety, and propagation delay of 2.1ns (typ) at 3.3V.
Technical Context
This device implements a standard push-pull CMOS NOR gate with fully specified operation across industrial temperature range (−40°C to +125°C) and supports partial power-down via IOFF circuitry that disables outputs to prevent backflow current when VCC = 0V. Input thresholds scale with VCC (e.g., VIH = 0.7×VCC at 4.5–5.5V).
Propagation delay is tightly controlled-4.5ns max at 3.3V over −40°C to +125°C-and output drive strength is graded per supply: −24mA/24mA at 3.3V, −32mA/32mA at 4.5V. ESD robustness exceeds 2kV HBM and 1kV CDM per JESD22.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Input Voltage Tolerance | Up to 5.5V - allows safe connection to higher-voltage signals without level shifters |
| IOFF Support | Active during power-down - prevents damaging current backflow when VCC = 0V |
| Output Drive (3.3V) | ±24mA - sufficient to drive multiple LVC loads or moderate capacitive loads (~30pF) |
| Propagation Delay (3.3V) | 0.5–4.5ns (min–max) - ensures timing predictability in high-speed digital control paths |
| ESD Protection | >2000V HBM, >1000V CDM - meets industrial reliability requirements without external protection |
| Operating Temperature | −40°C to +125°C - qualified for extended industrial and automotive under-hood environments |
Pinout & Package
SOT25 (3.0mm × 2.8mm × 1.2mm, 0.95mm lead pitch) surface-mount package with exposed pad not connected internally; thermal resistance θJA = 204°C/W on standard FR-4 board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | Primary logic input; 5.5V-tolerant, compatible with TTL and CMOS levels |
| 2 (B) | Data Input | Secondary logic input; identical electrical characteristics to Pin 1 |
| 3 (GND) | Ground Reference | Return path for all internal currents; must be low-impedance for noise immunity |
| 4 (Y) | Data Output | Push-pull CMOS output; drives high/low actively; supports bus hold if externally biased |
| 5 (VCC) | Power Supply | Core supply rail; IOFF activates automatically when VCC = 0V |
Key Features
| Feature | Design Value |
|---|---|
| Wide-Voltage Operation | 1.65–5.5V supply enables drop-in use across legacy and modern logic families without redesign |
| IOFF Partial Power-Down | Output high-impedance state activated automatically at VCC = 0V, eliminating need for external isolation switches |
| 5.5V-Tolerant Inputs | Accepts 5V signals while powered from 1.8V or 3.3V - eliminates discrete level-shifter components |
| Low Dynamic Power | Typical ICC = 0.1μA at 3.3V - reduces quiescent power in always-on subsystems like wake-up logic |
| Robust ESD Performance | HBM >2000V, CDM >1000V - meets IEC 61000-4-2 system-level surge immunity prerequisites |
Applications
| USB Peripheral Power Control | IoT Sensor Node Logic Isolation |
|---|---|
|
Use Scenario: Enable/disable 5V USB VBUS to peripheral devices based on host MCU GPIO status. IC Role / Device Role / Timing Role: NOR gate configured as active-low enable shutoff; inputs tied to MCU GPIO and pull-up, output controls high-side switch. Use Value: Prevents backfeed into powered-down MCU sections using IOFF, while 5.5V input tolerance accepts USB 5V detection signal directly. |
Use Scenario: Isolate sensor interrupt lines during MCU sleep mode to avoid spurious wake-ups. IC Role / Device Role / Timing Role: NOR gate used as bidirectional signal blocker; one input held low during sleep, forcing output high-impedance via IOFF when VCC drops. Use Value: Eliminates need for separate enable logic or analog switches - single gate provides both logic function and power-aware isolation. |
| Industrial PLC Input Conditioning | Automotive Body Control Module Signal Gating |
|
Use Scenario: Combine two 24V field inputs (via resistive dividers) into a single fault-indication signal for microcontroller. IC Role / Device Role / Timing Role: NOR gate implements OR-of-faults (inverted logic); tolerant of 5.5V input transients common in industrial environments. Use Value: Input voltage margin accommodates ±10% supply variation and EFT bursts without clamping diodes or additional protection. |
Use Scenario: Gate LIN bus wakeup signal to prevent false triggers during battery brownout conditions. IC Role / Device Role / Timing Role: NOR gate acts as voltage-domain translator between 5V LIN transceiver and 3.3V MCU; IOFF engages during undervoltage lockout. Use Value: Maintains signal integrity during transient brownouts (down to 1.65V) and blocks leakage paths when main supply collapses. |
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 | Texas Instruments part in SOT-23-5 package; identical logic function and 1.65–5.5V range but lacks explicit IOFF specification in datasheet | No guaranteed IOFF behavior - unsuitable for partial-power-down systems requiring backflow prevention | Select only if IOFF is not required and TI supply chain preference applies |
| 74AUP1G02GW,125 | Nexperia part in SC-70-5; lower static current (0.5μA max), wider temp range (−40°C to +125°C), but reduced drive (±4mA at 3.3V) | Insufficient drive for fanout >1 or capacitive loads >15pF; better suited for ultra-low-power always-on monitoring | Prefer for battery-powered nodes where drive demand is minimal and leakage budget is tight |
Compared with SN74LVC1G02DBVR and 74AUP1G02GW,125, the 74LVC1G02W5-7 uniquely guarantees IOFF functionality and delivers ±24mA drive at 3.3V - making it optimal for mixed-voltage signal routing where power sequencing and load driving coexist.

FAQ
Can 74LVC1G02W5-7 operate reliably at 1.65V supply?
Yes - the device is fully characterized down to 1.65V, with guaranteed propagation delay ≤8.0ns and output drive ≥±4mA at this minimum voltage. Input thresholds scale accordingly (VIH = 0.65×VCC), ensuring noise margins remain valid across the full range.
Does the SOT25 package include an exposed thermal pad?
No - the SOT25 package for 74LVC1G02W5-7 has five standard gull-wing leads with no exposed pad. Thermal performance relies on PCB copper area under the body; θJA = 204°C/W is measured on a 2oz FR-4 board with minimum recommended pad layout.
What happens to the output when VCC = 0V and inputs are pulled to 5V?
The IOFF circuit forces the output into high-impedance state, blocking current flow regardless of input voltage. Measured IOFF leakage is ≤±200μA at 5.5V, preventing damage to downstream circuitry or unintended biasing of powered-off sections.
Is 74LVC1G02W5-7 qualified for automotive applications?
As supplied, it is not AEC-Q100 qualified. However, Diodes offers automotive-grade variants (e.g., 74LVC1G02W5-7Q) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening - contact Diodes or Aetrix for qualified part numbers and qualification reports.
