Product details
Overview
74LVC2G34GW-Q100 from Nexperia is an automotive-qualified dual non-inverting buffer gate in TSSOP6 (SOT363-2) package, featuring Schmitt-trigger inputs, IOFF partial power-down protection, 1.65 V to 5.5 V supply range, ±24 mA output drive at 3.0 V, and AEC-Q100 Grade 1 qualification for under-hood control modules.
For engineers reviewing the 74LVC2G34GW-Q100 datasheet, 74LVC2G34GW-Q100 pinout, 74LVC2G34GW-Q100 application, or 74LVC2G34GW-Q100 equivalent, this device supports level translation between 3.3 V and 5 V domains, enables robust signal conditioning in noisy automotive environments, and provides fail-safe isolation during power sequencing.
Technical Context
This dual buffer implements two independent non-inverting logic paths with Schmitt-trigger inputs that tolerate slow-rising signals and reject noise up to 0.35×VCC hysteresis. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current and enabling hot-swap capability in multi-rail systems.
The device operates across 1.65 V–5.5 V supply while maintaining TTL-compatible input thresholds and delivering propagation delays as low as 0.5 ns (VCC = 4.5–5.5 V). It complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 for interoperability across voltage domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - Ensures <2 μA backfeed current during system power-down, protecting upstream drivers. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sustains full rail-to-rail swing into 50 Ω loads, supporting high-speed bus buffering. |
| Propagation Delay | 0.5 ns (min) to 4.0 ns (max) at VCC = 4.5–5.5 V - Guarantees sub-5 ns timing margin for 100 MHz clock distribution paths. |
| Input Hysteresis | Typ. 0.35×VCC - Rejects >1 Vpp noise on slow edges (e.g., sensor signals), eliminating false triggering. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Survives handling and board-level transients common in automotive assembly lines. |
| Ambient Temperature | -40 °C to +125 °C - Validated for engine control units, body controllers, and ADAS domain controllers. |
Pinout & Package
TSSOP6 plastic thin shrink small outline package (SOT363-2); 6 leads; body width 1.25 mm; pin 1 indicator located below marking code 'YA' in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First buffer input - Accepts overvoltage-tolerant signals up to 5.5 V regardless of VCC setting. |
| 2 | GND | Ground reference - Shared return path for both buffers; must be low-impedance to minimize ground bounce. |
| 3 | 2A | Second buffer input - Independent of 1A; supports asynchronous signal routing in dual-channel systems. |
| 4 | 2Y | Second buffer output - Delivers inverted logic state relative to 2A; drives downstream loads with ±24 mA capability. |
| 5 | VCC | Supply voltage - Powers both buffers; IOFF activation occurs automatically when VCC drops below 0.2 V. |
| 6 | 1Y | First buffer output - Provides rail-to-rail CMOS output compatible with TTL, LVTTL, and LVCMOS receivers. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable operation with slow-rise sensors (e.g., camshaft position) by rejecting noise and preventing metastability. |
| IOFF partial power-down | Prevents destructive back-current flow when VCC is unpowered, allowing safe insertion/removal in live backplanes. |
| Overvoltage-tolerant inputs | Accepts 5.5 V inputs while powered from 1.65 V - eliminates external clamping diodes in mixed-voltage ECUs. |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation at +125 °C ambient - meets thermal requirements for transmission control modules. |
| JEDEC-compliant voltage interfaces | Meets JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V) standards. |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
Use Scenario: Conditioning crankshaft position sensor signals before feeding to microcontroller capture timers. IC Role / Device Role / Timing Role: Dual buffer isolates noisy analog front-end from digital timing logic while preserving edge integrity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G34QDCURQ1 | TI part in SC-70-6 (SOT363-1); identical logic function but lacks Schmitt-trigger inputs. | Requires external RC filtering for noisy sensor inputs; unsuitable for direct crankshaft signal conditioning. | Select only when interfacing clean digital signals and footprint compatibility with SC-70 is required. |
| 74LVC2G125GW-Q100 | Nexperia triple-output variant with 3-state control; same AEC-Q100 Grade 1 rating and IOFF support. | Enables bus multiplexing but adds control pin overhead; not drop-in replaceable due to different pinout and function. | Choose when system requires tri-state capability for shared data lines, not simple buffering. |
Compared with SN74LVC2G34QDCURQ1, the 74LVC2G34GW-Q100 delivers superior noise immunity via Schmitt-trigger inputs and broader voltage tolerance; versus 74LVC2G125GW-Q100, it offers simpler pinout and lower static current for dedicated buffer-only roles.

FAQ
What is the maximum input voltage the 74LVC2G34GW-Q100 can tolerate when VCC = 1.8 V?
The device accepts inputs up to 5.5 V regardless of VCC level, per datasheet Table 5 (VI input voltage limit) and Section 1 General Description. This overvoltage tolerance eliminates need for external clamping when interfacing 5 V sensors or MCUs with a 1.8 V–powered buffer stage.
Does the 74LVC2G34GW-Q100 support hot-swap insertion in live systems?
Yes - its IOFF circuitry disables outputs and limits back-current to ±2 μA when VCC = 0 V (Table 7), enabling safe insertion into powered backplanes. This behavior is validated per AEC-Q100 stress testing and documented in Section 1 and Table 7.
How does the Schmitt-trigger input improve performance in automotive environments?
Schmitt-trigger action provides ~0.35×VCC hysteresis (Table 7), rejecting noise spikes and slow-rising interference typical of inductive crankshaft or camshaft sensors. This prevents false edge detection and ensures deterministic timing for engine timing calculations.
Can the 74LVC2G34GW-Q100 drive a 50 Ω transmission line directly?
Yes - with ±24 mA output drive at VCC = 3.0 V (Section 2 Features), it can source/sink sufficient current to terminate a 50 Ω line at 3.3 V logic levels. Measured VOL/VOH values (Table 7) confirm rail-to-rail swing under 24 mA load, meeting LVCMOS drive requirements.
