Product details
Overview
74LVC3G34GD,125 from Nexperia is a triple non-inverting buffer IC with Schmitt-trigger inputs, designed for level translation between 3.3 V and 5 V logic domains in mixed-voltage systems. It operates from 1.65 V to 5.5 V, delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and is rated for -40 °C to +125 °C operation - enabling use in industrial control I/O expansion and low-power sensor interface circuits.
For engineers reviewing the 74LVC3G34GD,125 datasheet, 74LVC3G34GD,125 pinout, 74LVC3G34GD,125 application, or 74LVC3G34GD,125 equivalent, key selection criteria include its overvoltage-tolerant 5.5 V inputs, guaranteed propagation delay ≤5.1 ns at 3.3 V, IOFF-enabled backflow current prevention during power sequencing, and compatibility with JEDEC standards JESD8-7 through JESD36.
Technical Context
The 74LVC3G34GD,125 implements three independent CMOS buffer stages, each with Schmitt-trigger input thresholds that tolerate slow-rising/falling signals and improve noise immunity. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking destructive back-current flow during hot-swap or partial power-down sequences.
All inputs accept voltages up to 5.5 V regardless of VCC (1.65–5.5 V), enabling bidirectional voltage translation without external biasing. The device complies with multiple JEDEC supply-voltage standards and supports operation across industrial and extended temperature ranges (-40 °C to +125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.65 V to 5.5 V - supports direct interfacing with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families |
| Input voltage tolerance | Up to 5.5 V - enables safe connection to higher-voltage sources without level-shifting components |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to drive moderate capacitive loads and multiple CMOS/TTL inputs |
| Propagation delay | ≤5.1 ns at VCC = 3.3 V - ensures timing integrity in high-speed digital control paths |
| IOFF leakage current | ±2 μA max at VCC = 0 V - prevents backfeed current during power sequencing or system sleep modes |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives |
| ESD robustness | HBM >2000 V, CDM >1000 V - reduces risk of field failure in handling and assembly |
Pinout & Package
The 74LVC3G34GD,125 is packaged in XSON8 (SOT996-2) - an 8-terminal, leadless, extremely thin small outline package measuring 1.25 mm × 1.0 mm × 0.35 mm, optimized for space-constrained PCB layouts and automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Buffer input | Three independent logic inputs; each accepts 0–5.5 V and triggers on Schmitt thresholds |
| 1Y, 2Y, 3Y | Buffer output | Three non-inverting buffered outputs; driven high/low per input state with rail-to-rail swing |
| GND | Ground reference | 0 V return path for all internal circuitry and output current sinks |
| VCC | Supply voltage | Primary power rail (1.65–5.5 V); powers all buffers and enables IOFF control when de-energized |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 1.65 V to 5.5 V operation eliminates need for separate voltage regulators in multi-rail systems |
| Overvoltage-tolerant inputs | 5.5 V absolute max input rating allows direct connection to legacy 5 V buses without clamping diodes |
| IOFF partial power-down | Automatic output disable at VCC = 0 V prevents back-current damage during hot-plug or staggered power-up |
| Schmitt-trigger inputs | Hysteresis improves noise margin and enables reliable operation with slow or noisy signal edges |
| JEDEC compliance | Meets JESD8-7, JESD8-5, JESD8C, and JESD36 - simplifies qualification for multi-voltage board designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G34DCUR | Same logic function and pinout; VSSOP8 package (2.3 mm width) vs. XSON8 (1.25 mm × 1.0 mm) | Higher board area usage; less suitable for ultra-dense layouts but easier manual rework | Select when board assembly uses standard pick-and-place tooling for VSSOP, or when thermal derating above 99 °C is required |
| 74LVC3G34GT,125 | Identical electrical specs; XSON8 package with 1.0 mm × 1.95 mm body (SOT833-1) vs. 1.25 mm × 1.0 mm (SOT996-2) | 0.35 mm height same, but 0.95 mm longer - impacts routing density and adjacent component clearance | Select when existing layout accommodates SOT833-1 footprint or when preferred distributor stock favors GT variant |
Compared with SN74LVC3G34DCUR and 74LVC3G34GT,125, the 74LVC3G34GD,125 offers the smallest PCB footprint (1.25 mm × 1.0 mm) while retaining identical electrical performance, IOFF behavior, and thermal rating - making it optimal for miniaturized industrial and portable electronics where board space is constrained.

FAQ
Does the 74LVC3G34GD,125 support true bidirectional level translation?
No. It is a unidirectional triple buffer: inputs accept 0–5.5 V regardless of VCC, but outputs swing only between GND and VCC. For bidirectional translation (e.g., I²C), a dedicated bus switch or auto-direction-sensing translator is required. This device excels in one-way signal conditioning and isolation tasks.
What is the maximum capacitive load the 74LVC3G34GD,125 can drive reliably?
Based on dynamic characteristics and CPD = 14 pF, the device reliably drives ≤50 pF loads while maintaining propagation delay ≤5.1 ns at 3.3 V. For heavier loads (>50 pF), output rise/fall times increase, potentially violating setup/hold timing in downstream logic - add series termination or reduce trace capacitance if exceeding this limit.
Can the 74LVC3G34GD,125 be used with VCC = 1.8 V and 5 V inputs simultaneously?
Yes. With VCC = 1.8 V, inputs tolerate up to 5.5 V, and VIH/VIL thresholds scale to ~1.2 V and ~0.7 V respectively. Output swing remains 0–1.8 V, enabling safe interfacing of 5 V sensors to 1.8 V MCUs - provided downstream receivers recognize 1.8 V logic-high as valid.
Is the XSON8 (SOT996-2) package RoHS and REACH compliant?
Yes. Nexperia confirms the 74LVC3G34GD,125 in SOT996-2 meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including SVHC screening. Lead-free matte tin terminations and halogen-free molding compound are standard; full compliance documentation is available via Nexperia's product portal.
