Product details
Overview
74LVC2G34GV-Q100 from Nexperia is an automotive-qualified dual non-inverting buffer gate with Schmitt-trigger inputs, IOFF partial power-down support, and 1.65 V to 5.5 V supply operation. It enables level translation between 3.3 V and 5 V logic domains in body control modules and infotainment interfaces, delivering ±24 mA output drive at 3.0 V and operating across -40 °C to +125 °C.
For engineers reviewing the 74LVC2G34GV-Q100 datasheet, 74LVC2G34GV-Q100 pinout, 74LVC2G34GV-Q100 application, or 74LVC2G34GV-Q100 equivalent, this device is selected for mixed-voltage signal buffering where IOFF protection, high noise immunity, and AEC-Q100 Grade 1 compliance are mandatory.
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 ±24 mA output current per channel. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.
The device 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), and supports input overvoltage tolerance up to 5.5 V regardless of supply voltage - enabling safe interfacing with higher-voltage peripherals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports 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 safe bus hold and prevents backfeed damage during hot-swap or partial power-down. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple CMOS/TTL loads or moderate capacitive traces in automotive ECUs. |
| Propagation Delay | 0.5 ns (min) to 4.0 ns (max) at VCC = 4.5–5.5 V - enables timing-critical signal routing in ADAS sensor interfaces. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows 5 V inputs to be safely applied while VCC is at 3.3 V or lower. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood and transmission control unit environments per AEC-Q100 Grade 1. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive robustness requirements for assembly and field operation. |
Pinout & Package
74LVC2G34GV-Q100 uses the SC-74 (TSOP6) package (SOT457), a 6-pin surface-mount plastic package with 1.7 mm body width, 0.65 mm lead pitch, and exposed pad-free construction suitable for reflow soldering in automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First buffer input - accepts 3.3 V or 5 V logic levels with Schmitt-trigger hysteresis for noise margin. |
| 2 | GND | Ground reference - must be low-impedance connection to minimize switching noise coupling into logic paths. |
| 3 | 2A | Second buffer input - electrically isolated from 1A; supports independent signal routing in dual-channel systems. |
| 4 | 2Y | Second buffer output - provides rail-to-rail CMOS output swing with ±24 mA drive capability at 3.0 V. |
| 5 | VCC | Supply voltage input - decoupling capacitor (100 nF) required within 3 mm for stable high-speed operation. |
| 6 | 1Y | First buffer output - matches 2Y in electrical characteristics; enables identical timing behavior across both channels. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including temperature cycling and humidity testing. |
| Schmitt-trigger inputs | Provides 0.3–0.5 V hysteresis depending on VCC, enabling reliable operation with slow-edge signals from sensors or mechanical switches. |
| IOFF partial power-down | Automatically disables outputs when VCC = 0 V, preventing current backflow into powered subsystems during sleep mode. |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V input signals regardless of VCC setting - eliminates need for external clamping diodes in mixed-voltage designs. |
| High noise immunity | CMOS input structure with >40 % VCC noise margin and ESD-hardened gates withstand >2000 V HBM in manufacturing and field use. |
Applications
| Body Control Module (BCM) | Instrument Cluster Interface |

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 same SOT-23-6 package; identical VCC range and IOFF, but lacks Schmitt-trigger inputs. | Less tolerant of slow-rising sensor signals; requires external filtering in switch-based automotive inputs. | Select when Schmitt action is unnecessary and TI supply chain preference applies. |
| 74LVC2G17GV-Q100 | Nexperia dual Schmitt-trigger buffer with same package and AEC-Q100 rating, but no IOFF circuitry. | Cannot be used in partial power-down architectures; outputs float during VCC=0, risking backfeed. | Select only for always-powered subsystems where IOFF is not required. |
Compared with SN74LVC2G34QDCURQ1 and 74LVC2G17GV-Q100, the 74LVC2G34GV-Q100 uniquely combines Schmitt-trigger inputs, IOFF protection, and AEC-Q100 Grade 1 in one SC-74 package - making it the only choice for automotive signal buffering requiring both noise immunity and safe power sequencing.

FAQ
Does 74LVC2G34GV-Q100 support true bidirectional signal translation?
No. The 74LVC2G34GV-Q100 is a unidirectional dual buffer with fixed input (1A/2A) and output (1Y/2Y) terminals. It does not implement bus transceiver functionality or automatic direction control. Its role is strictly level-tolerant signal forwarding - not data bus arbitration or bidirectional I²C/SPI line buffering.
Can 74LVC2G34GV-Q100 operate reliably at 1.65 V supply with 5 V inputs?
Yes. The device's overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC, and its recommended operating conditions specify 1.65 V minimum VCC. At 1.65 V, VIH is 0.65×VCC (≈1.07 V) and VIL is 0.35×VCC (≈0.58 V), ensuring correct logic interpretation of 5 V inputs via internal clamping and threshold design.
What is the maximum capacitive load this buffer can drive at 125 °C?
At +125 °C ambient and VCC = 3.0 V, the device maintains ≥2.0 V VOH at -24 mA and ≤0.80 V VOL at +24 mA. Based on dynamic characteristics and CPD = 20 pF, it reliably drives ≤50 pF loads with <5.1 ns propagation delay - typical for PCB traces plus one standard CMOS input in automotive ECU layouts.
How does IOFF behavior differ from standard high-impedance (Hi-Z) outputs?
IOFF actively disables the output FETs when VCC = 0 V, blocking both sourcing and sinking current paths. Unlike passive Hi-Z states, IOFF prevents backflow current from live buses into unpowered sections - critical for ISO 16750-compliant automotive power-down sequences where downstream circuits remain energized.
