Product details
Overview
74LVC1G34GX,125 from Nexperia is a single non-inverting CMOS buffer with Schmitt-trigger inputs, designed for level translation between 1.65 V–5.5 V logic domains in space-constrained mixed-voltage systems. It delivers ±24 mA output drive at 3.0 V, supports partial power-down via IOFF circuitry, and operates across –40 °C to +125 °C in the X2SON5 (SOT1226-3) package.
For engineers reviewing the 74LVC1G34GX,125 datasheet, 74LVC1G34GX,125 pinout, 74LVC1G34GX,125 application, or 74LVC1G34GX,125 equivalent, this device is selected for low-power signal buffering in portable IoT sensors, industrial I/O modules, and automotive body-control sub-systems requiring robust noise immunity and rail-to-rail input tolerance.
Technical Context
The 74LVC1G34GX implements a true single-gate buffer function with no internal inversion-input A directly drives output Y. Its Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at 3.3 V), enabling reliable operation with slow-rising signals from RC networks or mechanical switches.
IOFF circuitry actively disables the output when VCC = 0 V, limiting backflow current to ±2 μA and preventing bus contention during hot-swap or partial power-down sequences. Input voltage tolerance extends to 5.5 V regardless of supply, allowing direct interfacing with 5 V TTL outputs while powered from 1.8 V or 3.3 V rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables operation across legacy 5 V, standard 3.3 V, and ultra-low-power 1.8 V systems without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V sources even when VCC is as low as 1.65 V, eliminating external clamping diodes. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive multiple LVC loads or small capacitive traces (<30 pF) without signal degradation. |
| Propagation Delay | 0.5 ns (min) to 5.2 ns (max) at VCC = 3.0–3.6 V - Supports >100 MHz data rates in short-path digital interfaces. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - Ensures <100 nW standby power in powered-down subsystems, critical for battery longevity. |
| Operating Temperature | –40 °C to +125 °C - Qualified for under-hood automotive, industrial PLC, and outdoor edge-node deployments. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Survives handling and board-level ESD events without protection circuitry overhead. |
Pinout & Package
X2SON5 (SOT1226-3) package: plastic thermal-enhanced extremely thin small outline, 5-terminal, no leads, body size 0.8 × 0.8 × 0.32 mm, side-wettable flanks not present, pin 1 index located at lower-left corner below marking code "YN".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - electrically isolated; may be used for mechanical anchoring or thermal relief on PCB. |
| 2 | A | Data input with Schmitt-trigger hysteresis - accepts slow edges (≤10 ns/V transition rate) without oscillation or metastability. |
| 3 | GND | Ground reference - must be connected to system 0 V plane; serves as return path for all input/output currents. |
| 4 | Y | Push-pull output - actively drives HIGH/LOW; compatible with LVC, LV, and TTL logic families at same VCC. |
| 5 | VCC | Positive supply - powers internal logic and output stage; decoupling capacitor (100 nF) required within 2 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65–5.5 V operation enables single-bom support across 1.8 V microcontrollers, 3.3 V FPGAs, and 5 V legacy peripherals. |
| Overvoltage-Tolerant Inputs | 5.5 V max input rating allows direct interface with 5 V devices while powered from 1.65 V, reducing BOM count by eliminating discrete translators. |
| IOFF Partial Power-Down | Output high-impedance state at VCC = 0 V prevents backfeed current into powered-down sections, simplifying power sequencing in multi-rail systems. |
| Schmitt-Trigger Inputs | Typical 0.3 V hysteresis at 3.3 V suppresses noise-induced glitches on long traces or noisy sensor lines without external RC filtering. |
| Low Dynamic Power | 15 pF power dissipation capacitance (CPD) limits switching current - reduces dynamic power to <10 μW at 1 MHz with 3.3 V supply and 15 pF load. |
Applications
| Industrial Sensor Interface | Automotive Body Control |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G34DBVR | SOT-23-5 package (3.0 × 1.75 × 1.3 mm); higher thermal resistance (270 K/W vs. 220 K/W); no IOFF specification in datasheet. | Less suitable for partial power-down systems; requires larger PCB footprint. | Select when legacy SOT-23 assembly infrastructure exists and IOFF is not required. |
| 74AUP1G34GW,125 | Lower static current (0.9 μA max vs. 4 μA); narrower VCC range (0.8–3.6 V); no 5 V input tolerance. | Not usable in mixed 3.3 V/5 V environments; limited to battery-powered sub-3.6 V designs. | Select only for ultra-low-quiescent applications where 5 V compatibility is unnecessary. |

FAQ
Can the 74LVC1G34GX,125 be used with a 5 V input while powered from 1.8 V?
Yes. Its inputs are overvoltage tolerant up to 5.5 V independent of VCC, allowing direct connection to 5 V signals when VCC = 1.8 V. This eliminates external level-shifting components and is verified in Table 6 (VI input voltage range: 0–5.5 V) and Table 5 (VI absolute max: –0.5 to +6.5 V).
Does the IOFF feature require external control signals?
No. IOFF activates automatically when VCC drops to 0 V - no enable pin or external logic is needed. The output enters high-impedance state with leakage ≤±2 μA, as specified in Table 7 (IOFF power-off leakage current) and Section 1 (partial power-down description).
What is the maximum capacitive load the 74LVC1G34GX,125 can drive reliably?
It reliably drives up to 50 pF at VCC ≥ 3.0 V, as confirmed by test conditions in Table 10 (CL = 50 pF used for tPLH/tPHL measurement at 3.0–5.5 V). For 30 pF loads, propagation delay remains ≤4.1 ns (Table 8), supporting clean signal integrity in dense PCB layouts.
Is the X2SON5 (SOT1226-3) package compatible with standard reflow profiles?
Yes. The package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and withstands peak reflow temperatures up to 260 °C. Its 0.32 mm height and thermal-enhanced construction ensure uniform heating and void-free solder joints under standard lead-free profiles.
