Product details
Overview
74LVC1G34FW5-7 from Diodes Incorporated is a single non-inverting buffer gate with push-pull output, designed for level-shifting and signal conditioning in mixed-voltage digital systems. It operates from 1.65V to 5.5V, supports 5.5V-tolerant inputs, delivers ±24mA drive at 3.3V, and features IOFF circuitry for partial power-down protection-used in notebook I/O expansion and peripheral interface isolation.
For engineers reviewing the 74LVC1G34FW5-7 datasheet, 74LVC1G34FW5-7 pinout, 74LVC1G34FW5-7 application, or 74LVC1G34FW5-7 equivalent, key selection criteria include supply voltage flexibility (1.65–5.5V), 5.5V input tolerance, IOFF-enabled power-down isolation, and compact X1-DFN1010-6 (Type B) packaging for space-constrained logic routing.
Technical Context
This device implements a positive Boolean function (A = Y) with CMOS-compatible input thresholds and rail-to-rail push-pull output swing. Its IOFF circuit actively disables the output during VCC power-down, preventing back-current flow into powered subsystems-a critical requirement for hot-swap and multi-rail power sequencing.
Input voltage tolerance up to 5.5V enables direct interfacing between 3.3V logic and 5V peripherals without external level shifters. Propagation delay is specified down to 0.5ns (typ.) at 5.0V, supporting high-speed signal buffering in USB, display, and memory interface paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - supports operation across 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Input Voltage Tolerance | Up to 5.5V - allows safe connection to higher-voltage buses without clamping diodes |
| Output Drive Strength | ±24mA at VCC = 3.3V - sufficient to drive multiple LVC loads or moderate capacitive traces |
| IOFF Leakage Current | ±10μA max - ensures minimal current backflow when VCC = 0V, enabling safe partial power-down |
| Propagation Delay | 0.5ns (min) to 5.5ns (max) at VCC = 3.3V - meets timing requirements for sub-200MHz digital interfaces |
| ESD Protection | 2kV HBM / 1kV CDM - exceeds JEDEC JESD22 standards for board-level handling robustness |
| Operating Temperature | –40°C to +125°C - qualified for industrial and extended-temperature embedded applications |
Pinout & Package
X1-DFN1010-6 (Type B) package: 1.0mm × 1.0mm, 0.35mm height, 6-pin leadless DFN with exposed thermal pad (not electrically connected), moisture sensitivity level 1, NiPdAu terminal finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output stage return path |
| 2 | A | Single logic input; accepts 0V–5.5V signals regardless of VCC level |
| 3 | NC | No internal connection; must be left floating or tied to GND/VCC per layout guidelines |
| 4 | VCC | Primary power supply input; powers internal logic and output driver stages |
| 5 | Y | Non-inverting buffered output; rail-to-rail swing with ±24mA sink/source capability |
| 6 | NC | No internal connection; no electrical function; avoid routing signals to this pad |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65V–5.5V operation enables drop-in use across legacy and modern low-voltage logic families |
| 5.5V-Tolerant Inputs | Eliminates need for external level translators when interfacing 5V sensors or legacy peripherals to 3.3V microcontrollers |
| IOFF Partial Power-Down | Automatically isolates output during VCC ramp-down, preventing bus contention in multi-supply systems |
| Low Dynamic Power | 16pF typical power dissipation capacitance at 10MHz - reduces switching noise and system-level power budget impact |
| Compact DFN Packaging | X1-DFN1010-6 (1.0×1.0mm) saves >70% board area vs. SOT25 while maintaining thermal performance (θJA = 435°C/W) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G34DBVR | SOT-23-5 package (larger footprint, 2.9×1.3mm); identical electrical specs; no NC pins | Better suited for prototyping or manual assembly due to gull-wing leads; less optimal for ultra-dense layouts | Select when board space permits and hand-soldering or test probing is required |
| 74LVC1G34FW4-7 | X2-DFN1010-6 package (same size but different pinout: pins 1–6 = GND, A, VCC, Y, NC, NC); identical electrical behavior | Requires updated PCB layout; same thermal and ESD performance; pin 3 is VCC instead of NC | Choose only if redesigning for alternate pin compatibility or sourcing continuity |
Compared with SN74LVC1G34DBVR and 74LVC1G34FW4-7, the 74LVC1G34FW5-7 offers optimal density for automated high-volume assembly via its Type B pinout and smallest possible footprint among Diodes' LVC1G34 variants, while retaining full functional equivalence and IOFF safety.

FAQ
Can 74LVC1G34FW5-7 operate with a 1.5V supply?
No. The recommended minimum operating voltage is 1.65V per the datasheet's Recommended Operating Conditions table. At 1.5V, the device may not meet VIH/VIL thresholds or output drive specifications, risking logic misstates or excessive ICC. Data retention is supported down to 1.5V, but functional operation requires ≥1.65V.
What is the thermal resistance (θJA) of the X1-DFN1010-6 (Type B) package?
The junction-to-ambient thermal resistance (θJA) for the X1-DFN1010-6 (Type B) package is 435°C/W under standard test conditions (FR-4 board, 2oz copper, minimum recommended pad layout). This value assumes proper thermal pad soldering and is critical for estimating junction temperature rise under continuous 24mA output loading.
How does IOFF functionality behave when VCC = 0V but input A is held at 5.5V?
When VCC = 0V and A = 5.5V, the IOFF circuit disables the output Y, limiting leakage to ≤±10μA. No damaging back-current flows into the VCC rail because the internal output FETs are fully cut off-verified by the Absolute Maximum Ratings table specifying VO = –0.5V to 6.5V in IOFF state.
Is the 74LVC1G34FW5-7 RoHS and REACH compliant?
Yes. The part is fully RoHS 3 (2015/863/EU) compliant with no purposely added lead, and halogen- and antimony-free ("Green") per Diodes' definition: Br <900ppm, Cl <900ppm (Br+Cl <1500ppm), Sb <1000ppm. Compliance documentation is available via Diodes' quality portal.
