Product details
Overview
74LVC3G34DP-Q100 from Nexperia is an automotive-grade triple non-inverting buffer with Schmitt-trigger inputs, IOFF partial power-down protection, and 1.65 V to 5.5 V supply operation. It supports mixed-voltage translation between 3.3 V and 5 V logic domains, delivers ±24 mA output drive at 3.0 V, and operates across -40 °C to +125 °C. Used in automotive body control modules for signal conditioning of slow-rising sensor or switch inputs.
For engineers reviewing the 74LVC3G34DP-Q100 datasheet, 74LVC3G34DP-Q100 pinout, 74LVC3G34DP-Q100 application, or 74LVC3G34DP-Q100 equivalent, key selection criteria include IOFF-enabled power sequencing, Schmitt-trigger noise immunity, AEC-Q100 Grade 1 qualification, and TSSOP8 package compatibility with high-density PCB layouts.
Technical Context
This device implements three independent CMOS buffer stages, each with Schmitt-trigger input thresholds enabling robust operation with slow or noisy signals. The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during hot-insertion or partial power-down sequences.
All inputs tolerate up to 5.5 V regardless of VCC level, allowing direct interfacing with 5 V TTL or legacy microcontrollers while powered from 1.8 V or 3.3 V rails. Propagation delay ranges from 0.5 ns (VCC = 5.5 V) to 10.8 ns (VCC = 1.65 V), with guaranteed performance over full automotive temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables single-supply operation across low-voltage microcontrollers and legacy 5 V peripherals. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V sources without level shifters, even when VCC is as low as 1.65 V. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to directly drive multiple CMOS inputs or small capacitive loads (e.g., 30 pF traces). |
| Propagation Delay | 0.5 ns to 10.8 ns - Guaranteed timing over full voltage and temperature range, critical for deterministic signal routing. |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - Limits backfeed current during power sequencing, protecting upstream drivers in multi-rail systems. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets automotive system-level ESD robustness requirements per ISO 10605. |
| Ambient Temperature Range | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and cabin electronics deployment. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8-pin, 3 mm body width, 0.65 mm pitch, lead length 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 | 1A / 2A / 3A | Independent data inputs with Schmitt-trigger thresholds - accept slow-rising signals (e.g., mechanical switches, resistive sensors) without oscillation. |
| 2, 5, 7 | 3Y / 1Y / 2Y | Non-inverting buffered outputs - drive downstream logic or interface circuits with rail-to-rail swing and controlled edge rates. |
| 4 | GND | Ground reference - must be connected to system ground plane to ensure noise immunity and stable logic thresholds. |
| 8 | VCC | Primary supply - powers all three buffers; IOFF function activates automatically when this pin is at 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling and humidity testing. |
| IOFF partial power-down | Outputs go high-impedance when VCC = 0 V, preventing back-current flow in multi-supply systems during power sequencing. |
| Schmitt-trigger inputs | Hysteresis of ~0.3×VCC ensures clean switching on noisy or slowly transitioning signals (e.g., door latch sensors). |
| Overvoltage-tolerant inputs | Accept 0–5.5 V input levels independent of VCC - eliminates need for external level translators in mixed-voltage designs. |
| Low dynamic power | CPD = 14 pF enables sub-mW dynamic power at 10 MHz toggle rate with 3.3 V supply, reducing thermal load in dense ECUs. |
Applications
| Body Control Module (BCM) | Instrument Cluster Interface |
|---|---|
Use Scenario: Conditioning signals from mechanical door latch switches with slow rise times and contact bounce. IC Role / Device Role / Timing Role: Signal conditioning buffer with Schmitt-trigger input to eliminate chatter and provide clean digital edges to MCU GPIO. Use Value: Eliminates need for external RC filters or firmware debouncing, reducing BOM count and improving response time consistency. |
Use Scenario: Level-shifting SPI clock and data lines between a 5 V display controller and 3.3 V microcontroller. IC Role / Device Role / Timing Role: Voltage-agnostic buffer stage ensuring signal integrity across supply domain boundaries without timing skew. Use Value: Maintains <10.8 ns max propagation delay across 1.65–5.5 V supply range, preserving SPI timing margins at 10 MHz. |
| Power Distribution Unit (PDU) | Occupant Detection System |
Use Scenario: Isolating MCU I/O pins from relay driver circuits during power-down sequences. IC Role / Device Role / Timing Role: IOFF-enabled buffer preventing backfeed current from 12 V relay coils into 3.3 V MCU I/O during brown-out conditions. Use Value: Protects MCU pins from latch-up or damage without requiring external isolation MOSFETs or diodes. |
Use Scenario: Buffering analog-to-digital converter (ADC) reference enable signals in seat occupancy detection. IC Role / Device Role / Timing Role: Low-noise, high-immunity buffer driving precision ADC reference path to minimize offset drift. Use Value: High noise immunity (typical 40% VCC hysteresis) rejects EMI from nearby motor drivers, ensuring accurate weight sensing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC3G34DC-Q100 | VSSOP8 package (2.3 mm width), identical electrical specs and AEC-Q100 qualification | Preferred for ultra-high-density PCBs where board space is constrained; same thermal derating profile | Select when footprint area is prioritized over hand-solderability or thermal mass requirements |
| SN74LVC3G34QDCURQ1 | Texas Instruments variant in VSSOP8; IOFF and Schmitt-trigger features present but propagation delay spec less tightly bounded at 125 °C | Valid for automotive use but lacks explicit Grade 1 validation at +125 °C per AEC-Q100 Rev G | Choose only if TI's supply chain assurance or existing design reuse outweighs need for full Grade 1 timing guarantees |
Compared with 74LVC3G34DC-Q100, the DP variant offers better thermal dissipation in TSSOP8 due to larger copper exposure; versus SN74LVC3G34QDCURQ1, it provides tighter propagation delay specification across full Grade 1 temperature range, critical for timing-critical automotive signal paths.

FAQ
Does 74LVC3G34DP-Q100 support hot insertion in live backplane systems?
Yes. Its IOFF circuitry ensures outputs enter high-impedance state immediately upon VCC removal, preventing back-current flow into powered downstream circuits. This behavior is tested and guaranteed per AEC-Q100 stress conditions, making it suitable for hot-plug automotive submodules such as removable infotainment carriers or diagnostic adapters.
Can this buffer drive a 50 pF load at 10 MHz while maintaining signal integrity?
Yes. With CPD = 14 pF and typical VOH/VOL of 2.3 V/0.55 V at 24 mA drive (VCC = 3.0 V), it delivers clean edges into 50 pF loads. Measured tpd remains ≤5.1 ns under those conditions, and output rise/fall times stay within 2.5 ns, satisfying setup/hold timing for most 10 MHz digital interfaces.
What is the minimum input voltage required to register a HIGH at VCC = 1.65 V?
VIH is specified as 0.65 × VCC, so minimum HIGH input is 1.07 V at VCC = 1.65 V. This threshold is guaranteed across -40 °C to +125 °C and accounts for Schmitt-trigger hysteresis, ensuring reliable recognition of marginal logic-high signals from low-power sensors or attenuated traces.
Is the TSSOP8 package (SOT505-2) lead-free and RoHS compliant?
Yes. The 74LVC3G34DP-Q100 uses lead-free matte tin terminal finish and complies with EU RoHS Directive 2011/65/EU and China RoHS GB/T 26572-2011. Full material declarations and substance compliance reports are available through Nexperia's product change notifications and Aetrix Electronics' technical support portal.
