Product details
Overview
74LVC1G34FX4-7 from Diodes Incorporated is a single non-inverting buffer gate with push-pull output, designed for voltage-level translation and signal conditioning in mixed-voltage digital systems. It operates from 1.65V to 5.5V, tolerates 5.5V inputs, supports IOFF partial power-down, delivers ±24mA drive at 3.3V, and is packaged in X2-DFN1409-6 (1.4mm × 0.9mm, 0.4mm pitch). It enables robust signal isolation in portable computing and peripheral interfaces.
For engineers reviewing the 74LVC1G34FX4-7 datasheet, 74LVC1G34FX4-7 pinout, 74LVC1G34FX4-7 application, or 74LVC1G34FX4-7 equivalent, key selection criteria include its 5.5V-tolerant inputs, IOFF-enabled power-down leakage control (<±10μA), sub-5ns propagation delay at 3.3V, ±24mA output drive capability, and compatibility with 1.8V/2.5V/3.3V/5V logic families.
Technical Context
This device implements a single positive-logic buffer (A → Y) with CMOS input structure and push-pull output stage. Its IOFF circuit actively disables both output FETs during power-down, preventing back-current flow when VCC = 0V while inputs remain biased up to 5.5V.
It meets JESD22 ESD standards (≥2000V HBM, ≥1000V CDM) and JESD78 latch-up immunity (>100mA), and supports operation across -40°C to +125°C ambient. Input thresholds scale with VCC (e.g., VIH = 0.7×VCC at 4.5–5.5V), enabling reliable interfacing between disparate supply domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - Enables direct use across 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5V - Allows connection to higher-voltage buses while powered from lower VCC (e.g., 1.8V supply driving 5V-tolerant input). |
| IOFF Leakage Current | <±10μA at VCC = 0V - Prevents damaging back-current during partial power-down, critical for hot-swap and low-power standby modes. |
| Output Drive Strength | ±24mA at VCC = 3.3V - Sufficient to drive moderate capacitive loads (e.g., PCB traces, multiple gate inputs) with fast edge rates. |
| Propagation Delay | 0.5–5.5ns (typ/max) at VCC = 3.3V - Supports >100MHz signal routing in timing-critical paths like clock distribution or data enable lines. |
| ESD Protection | >2000V HBM, >1000V CDM - Ensures robustness during board handling and system integration without external protection diodes. |
| Operating Temperature | -40°C to +125°C - Qualified for industrial and extended-temperature embedded applications including automotive infotainment peripherals. |
Pinout & Package
X2-DFN1409-6 is a 0.4mm-pitch, 1.4mm × 0.9mm chip-scale package with six terminals; two are no-connect (NC), one is ground (GND), one is supply (VCC), one is input (A), and one is output (Y). The package uses NiPdAu terminal finish and is moisture-sensitive Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output stage return path. |
| 2 | A | CMOS-compatible digital input; accepts 0V to 5.5V regardless of VCC value. |
| 3 | NC | No internal connection; must be left unconnected or tied to GND/VCC per layout best practice. |
| 4 | VCC | Primary power supply rail; powers internal logic and output driver stage (1.65–5.5V). |
| 5 | NC | No internal connection; electrically isolated; no routing or soldering required. |
| 6 | Y | Push-pull CMOS output; actively drives high/low with rail-to-rail swing and ±24mA capability at 3.3V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65V–5.5V operation allows single-buffer reuse across multiple voltage domains in multi-rail systems. |
| 5.5V-Tolerant Inputs | Enables direct interface with legacy 5V logic or I²C pull-ups without external resistors or translators. |
| IOFF Partial Power-Down | Eliminates back-current paths when VCC is off, preserving integrity of shared buses during sleep mode. |
| Low Dynamic Power | 16pF CPD at 10MHz ensures minimal switching current draw-critical for battery-powered devices. |
| Small Footprint | X2-DFN1409-6 (1.4mm × 0.9mm) saves PCB area in space-constrained applications like ultraportable SSD controllers. |

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 (2.9mm × 1.6mm); lacks NC pins; same electrical specs but larger footprint and higher θJA (204°C/W vs 470°C/W). | Better suited for prototyping or low-density boards where manual rework is needed; less optimal for ultra-compact automated assembly. | Select when board real estate is unconstrained and hand-soldering support is required. |
| 74LVC1G34FW4-7 | X2-DFN1010-6 package (1.0mm × 1.0mm); identical function and IOFF behavior but smaller pad layout and 0.35mm pitch. | Higher routing density possible, but requires tighter stencil design and placement accuracy than FX4's 0.4mm pitch. | Prefer for next-gen miniaturized designs where 0.1mm pitch reduction justifies process validation effort. |
Compared with SN74LVC1G34DBVR and 74LVC1G34FW4-7, the 74LVC1G34FX4-7 offers the best thermal resistance balance (θJA = 470°C/W) and mechanical robustness for high-volume automated assembly, while retaining full functional equivalence and superior board-area efficiency over SOT-23.

FAQ
Can 74LVC1G34FX4-7 operate with VCC = 1.5V?
No. The recommended minimum operating voltage is 1.65V per the datasheet's Recommended Operating Conditions table. At 1.5V, parameters such as VOH, VOL, and tPD are not guaranteed, and functionality may be unreliable. Data retention only is specified down to 1.5V-but not active operation.
What is the maximum capacitive load this buffer can drive reliably?
Based on the 16pF CPD specification and ±24mA drive at 3.3V, the device reliably drives ≤30pF loads while maintaining tPD ≤5.5ns and edge monotonicity. For heavier loads (e.g., >50pF), series termination or a second-stage buffer is recommended to avoid overshoot and timing skew.
Is the X2-DFN1409-6 package lead-free and RoHS compliant?
Yes. The 74LVC1G34FX4-7 uses NiPdAu terminal finish and is fully RoHS 3 compliant (EU Directive 2015/863/EU), with <900ppm bromine, <900ppm chlorine, and <1000ppm antimony-certified as "Green" per Diodes' definitions.
How does IOFF behave when VCC = 0V and input is held at 5.5V?
When VCC = 0V, the IOFF circuit disables both output FETs, limiting leakage current to <±10μA even with A = 5.5V. This prevents reverse current flow into the powered-down VCC rail, protecting upstream regulators and avoiding false logic states on shared buses.
