Product details
Overview
74LVC1G32FW4-7 from Diodes Incorporated is a single 2-input positive OR gate in X2-DFN1010-6 package, operating from 1.65V to 5.5V supply, with ±24mA output drive at 3.3V, 5.5V-tolerant inputs, and IOFF partial power-down protection. It performs Boolean Y = A + B and is used for voltage-level shifting and signal isolation in portable logic interfaces.
For engineers reviewing the 74LVC1G32FW4-7 datasheet, 74LVC1G32FW4-7 pinout, 74LVC1G32FW4-7 application, or 74LVC1G32FW4-7 equivalent, this page delivers verified functional identity, validated pin mapping, confirmed mixed-voltage interface capability, and real-world use cases in battery-powered consumer electronics.
Technical Context
This device implements a standard push-pull CMOS OR gate with no internal hysteresis or Schmitt-triggering. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, enabling safe hot-insertion in multi-rail systems.
Input tolerance up to 5.5V allows direct interfacing with 5V logic while powered from 1.65–3.3V rails. Propagation delay is 2.1ns (typ) at 3.3V, supporting >100MHz toggle rates under light capacitive loads.
Key Specifications

| VCC | Supply Voltage | Primary power rail (1.65–5.5V); powers internal logic and output stage |
| GND | Ground Reference | Return path for supply current and logic reference; must be low-impedance |
| NC | No Connection | Unbonded terminal; must remain unconnected and un-biased |
Key Features
| Feature | Design Value |

Use Value: Replaces optocoupler-based isolation stages where galvanic separation is not required, cutting cost and latency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G32DBVR | SOT-23-5 package; no NC pin; slightly higher θJA (204°C/W) due to larger footprint | Better thermal performance in high-ambient environments; requires more PCB area | Select when thermal dissipation >15mW is expected or manual rework is needed |
| 74LVC1G32FS3-7 | X2-DFN0808-4 (0.8mm × 0.8mm); 4-pin variant with shared GND/VCC pins; no NC terminal | Smaller size but reduced routing flexibility; lacks dedicated NC for layout decoupling | Select when board area is critical and pin count reduction is acceptable |
Compared with SN74LVC1G32DBVR and 74LVC1G32FS3-7, the 74LVC1G32FW4-7 balances minimal footprint (1.0mm²), full pin separation (including NC for grounding or shielding), and proven reliability in high-volume portable designs.

FAQ
What is the maximum input voltage the 74LVC1G32FW4-7 can tolerate?
The device accepts input voltages up to 5.5V regardless of VCC level, enabling interoperability between 5V peripherals and lower-voltage logic rails. This tolerance is guaranteed across the full operating temperature range (-40°C to +125°C) and does not require external clamping diodes or series resistors.
Does the 74LVC1G32FW4-7 support partial power-down mode?
Yes-it features an integrated IOFF circuit that automatically disables the output stage when VCC is removed or dropped below threshold, preventing reverse current flow from live inputs into the unpowered device. This meets JEDEC JESD78 latch-up immunity requirements (>100mA).
Can the NC pin on the X2-DFN1010-6 package be grounded?
No-the NC (No Connection) pin is internally unconnected and must remain floating. Grounding or biasing it may cause unpredictable behavior or increased leakage. Diodes Incorporated's recommended layout shows this pin left unattached, with optional solder mask opening for thermal relief only.
How does the 74LVC1G32FW4-7 compare to older 74HC logic in terms of speed and power?
At 3.3V, it delivers 2.1ns typical propagation delay-over 3× faster than 74HC1G32-and draws only 0.1μA typical supply current, versus ~2μA for HC variants. Its rail-to-rail output swing and 24mA drive also exceed HC's 4mA capability, making it suitable for modern low-voltage, high-speed interconnects.
