Product details
Overview
74LVC1G34GW,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. It features ±24 mA output drive at 3.0 V, IOFF partial power-down protection, and operates across –40 °C to +125 °C. Used in mixed-voltage I/O interfacing on industrial microcontroller peripheral buses.
For engineers reviewing the 74LVC1G34GW,125 datasheet, 74LVC1G34GW,125 pinout, 74LVC1G34GW,125 application, or 74LVC1G34GW,125 equivalent, this device serves as a robust, low-power unidirectional signal conditioner where voltage domain bridging, noise immunity, and power-state isolation are required.
Technical Context
The 74LVC1G34GW implements a single-buffer function with hysteresis-enabled Schmitt-trigger inputs, enabling reliable operation with slow-rising or noisy signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.
It complies with JEDEC standards 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), supporting interoperability across legacy TTL and modern low-voltage CMOS systems without external biasing.
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. |
| Input Voltage Tolerance | Up to 5.5 V - Allows overvoltage-tolerant input driving from higher-voltage sources without clamping diodes. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive moderate capacitive loads and multiple CMOS inputs. |
| Propagation Delay | 0.5 ns (min) to 4.1 ns (max) at VCC = 3.0–3.6 V - Supports high-speed digital signaling up to ~100 MHz edge rates. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - Ensures safe hot-swap and partial power-down operation without bus contention. |
| Operating Temperature | –40 °C to +125 °C - Qualified for under-hood automotive, industrial control, and extended-range embedded applications. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Robust handling during PCB assembly and field operation. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, lead pitch 0.65 mm, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - electrically isolated; must remain unconnected on PCB. |
| 2 | A | CMOS input with Schmitt-trigger hysteresis - accepts slow or noisy signals without oscillation. |
| 3 | GND | Ground reference (0 V) - return path for all internal currents and output load sink. |
| 4 | Y | Inverted-output buffer stage - delivers rail-to-rail CMOS-compatible output with ±24 mA capability. |
| 5 | VCC | Primary supply rail - powers internal logic and output stage; supports 1.65–5.5 V operation. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables clean switching with input rise/fall times up to 20 ns/V (1.65–2.7 V) or 10 ns/V (2.7–5.5 V), eliminating metastability on noisy lines. |
| IOFF partial power-down | Disables Y output and isolates A–Y path when VCC = 0 V, preventing backfeed into powered subsystems during hot-plug or sleep modes. |
| Overvoltage-tolerant inputs | Accepts VI up to 5.5 V independent of VCC, allowing direct connection to 5 V peripherals even when VCC = 1.8 V. |
| Wide temperature range | Specified from –40 °C to +125 °C - validated for use in engine control units, motor drives, and outdoor industrial gateways. |
| Low dynamic power | CPD = 15 pF - limits switching power dissipation in high-frequency clock or data buffering applications. |
Applications
| Industrial Sensor Interface | Microcontroller GPIO Expansion |
|---|---|
|
Use Scenario: Interfacing analog sensor ADC outputs with varying output swing (e.g., 0–3.3 V or 0–5 V) to a 1.8 V microcontroller I/O bank. IC Role / Device Role / Timing Role: Level-shifting buffer with noise filtering via Schmitt-trigger input, ensuring glitch-free sampling. Use Value: Eliminates need for external pull-ups or discrete FET translators while maintaining timing integrity across voltage domains. |
Use Scenario: Driving LED indicators or optocoupler inputs from low-drive MCU GPIO pins in programmable logic controllers. IC Role / Device Role / Timing Role: Output driver amplifier - boosts current capability beyond MCU's native 4 mA limit to reliably sink 24 mA per LED. Use Value: Reduces BOM count by replacing discrete transistor+resistor stages with a single 5-pin IC. |
| Automotive Body Control Module | USB-C Power Delivery Sequencing |
|
Use Scenario: Isolating wake-up signal lines between always-on CAN transceivers (5 V tolerant) and deep-sleep MCU domains (1.8 V). IC Role / Device Role / Timing Role: Power-state-aware buffer - IOFF prevents leakage-induced false wake events during MCU VCC shutdown. Use Value: Guarantees zero standby current contribution from the buffer during system sleep, meeting ISO 16750-2 quiescent current targets. |
Use Scenario: Enabling/disabling VBUS discharge paths in USB-C PD controllers based on CC line state detection. IC Role / Device Role / Timing Role: Signal conditioning gate - translates open-drain CC logic to push-pull control of NMOS discharge FETs. Use Value: Provides fast, rail-aligned enable signals with sub-5 ns propagation delay, critical for <100 ms PD compliance discharge timing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar single-buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G34GV | SC-74A (SOT753) package: larger footprint (3.1 × 2.7 mm vs. 2.2 × 1.35 mm), lower thermal resistance (3.8 mW/K derating above 85 °C). | Better suited for manual soldering or high-reliability reflow where TSSOP5 handling is challenging. | Select GV for prototyping or low-volume production where pick-and-place compatibility is less critical than thermal margin. |
| SN74LVC1G34DBVR | Texas Instruments part in SOT-23-5 (same pinout); identical logic function but higher ICC (max 10 μA vs. 4 μA) and no IOFF spec at VCC = 0 V. | Lacks guaranteed power-down isolation - unsuitable for hot-swap or partial-power systems requiring backfeed prevention. | Choose GW over DBVR when IOFF functionality and sub-5 μA supply current are mandatory for system-level power management. |
Compared with 74LVC1G34GV and SN74LVC1G34DBVR, the 74LVC1G34GW offers the smallest footprint among pin-compatible variants and the only guaranteed IOFF behavior, making it optimal for space-constrained, thermally sensitive, and power-gated designs.

FAQ
Does the 74LVC1G34GW,125 support true bidirectional signal translation?
No. The 74LVC1G34GW,125 is a unidirectional buffer (A → Y only). It lacks automatic direction control or bus-hold circuitry. For bidirectional level shifting, consider dedicated translators like the NXH0108 or TXB0108, which integrate direction sensing and dual-supply rails.
Can Pin 1 (n.c.) be used as a heatsink pad or grounded for thermal improvement?
No. Pin 1 is internally unconnected and electrically isolated. Connecting it to GND or any potential creates no thermal benefit and risks mechanical stress or solder wicking that may compromise adjacent solder joints. Thermal performance relies solely on the GND (Pin 3) and VCC (Pin 5) terminations.
What is the minimum input rise time the Schmitt-trigger input can reliably handle?
At VCC = 3.3 V, the input transition rate specification is ≤10 ns/V. With typical hysteresis of ~0.5 V, the input can tolerate rise/fall times up to ~5 ns without chatter. For slower edges (>100 ns), ensure VI stays within valid HIGH/LOW thresholds defined in Table 7 (e.g., VIH ≥ 2.0 V, VIL ≤ 0.8 V at 3.3 V).
Is the 74LVC1G34GW,125 compliant with AEC-Q200 for automotive use?
No. While qualified from –40 °C to +125 °C and widely used in automotive body electronics, the 74LVC1G34GW,125 is not AEC-Q200 stress-tested. For Q200-compliant alternatives, specify the automotive-grade variant 74LVC1G34GW-Q100, which undergoes additional temperature cycling, humidity, and vibration validation.
