Product details
Overview
74LVC3G34DC-Q100 from Nexperia is an automotive-grade triple non-inverting buffer IC 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 sensor or switch inputs.
For engineers reviewing the 74LVC3G34DC-Q100 datasheet, 74LVC3G34DC-Q100 pinout, 74LVC3G34DC-Q100 application, or 74LVC3G34DC-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, IOFF-enabled backflow prevention during power sequencing, Schmitt-trigger noise immunity on all inputs, and guaranteed 5.5 V overvoltage-tolerant inputs in 1.65 V–5.5 V systems.
Technical Context
This device implements three independent CMOS buffer stages with Schmitt-trigger input thresholds-enabling robust operation with slow-rising signals (e.g., mechanical switch debouncing or resistive sensor outputs). Each channel features symmetric HIGH/LOW input voltage thresholds defined per JEDEC standards (JESD8-7/8-5/8C/36), ensuring interoperability across voltage domains.
The IOFF circuit actively disables outputs when VCC = 0 V, blocking reverse current flow from powered downstream logic into unpowered upstream sections-a critical requirement for hot-swap and multi-rail automotive subsystems. Propagation delay ranges from 0.5 ns (at 5 V) to 10.8 ns (at 1.65 V), with load-dependent timing validated under 30–50 pF capacitive loads.
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. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V signals even when powered from 1.65 V–3.3 V rails. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive multiple CMOS/TTL loads or moderate PCB trace capacitance. |
| Propagation Delay | 0.5 ns (min) to 10.8 ns (max) - Timing-critical for signal integrity in CAN/LIN bus interface buffering or sensor preprocessing paths. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - Ensures <1 μA backflow risk during power-down sequences in domain-isolated ECUs. |
| Ambient Temperature Range | -40 °C to +125 °C - Validated for under-hood automotive applications including engine control and lighting modules. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets stringent AEC-Q100 stress requirements for assembly and field reliability. |
Pinout & Package
VSSOP8 package (SOT765-1): plastic very thin shrink small outline, 8-lead, 2.3 mm body width, 0.65 mm pitch, pin 1 indicator below marking "Y34".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 | 1A / 2A / 3A | Independent data inputs with Schmitt-trigger hysteresis-accepts slow edges from switches, sensors, or open-drain sources. |
| 2, 5, 7 | 3Y / 2Y / 1Y | Non-inverting buffered outputs-each drives one logic path with rail-to-rail swing and IOFF disable capability. |
| 4 | GND | Reference ground for all I/O and internal circuitry-must be low-impedance for noise immunity and ESD discharge path. |
| 8 | VCC | Single supply rail powering all three buffers-supports dynamic voltage scaling and brown-out tolerant operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling, humidity, and vibration stress. |
| IOFF partial power-down | Outputs automatically high-impedance when VCC = 0 V-prevents backfeeding and enables safe hot-plug or domain isolation. |
| Schmitt-trigger inputs | Hysteresis ≥0.35VCC ensures reliable switching with noisy or slow-rising signals (e.g., door latch or seat position sensors). |
| Overvoltage-tolerant inputs | Withstands 5.5 V regardless of VCC setting-eliminates need for external clamping diodes in mixed-voltage clusters. |
| JEDEC-compliant voltage interfaces | Fully compliant with 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). |
Applications
| Body Control Module (BCM) | Powertrain Sensor Interface |
|---|---|
|
Use Scenario: Buffering digital inputs from door lock actuators, window switches, and mirror position sensors in a centralized BCM. IC Role / Device Role / Timing Role: Signal conditioner and voltage translator-converts 5 V switch signals to 3.3 V microcontroller GPIO while rejecting contact bounce noise.

Use Scenario: Isolating and conditioning crankshaft position sensor pulses before routing to engine control unit (ECU) timing capture logic. IC Role / Device Role / Timing Role: Low-jitter buffer stage-preserves edge integrity of analog-to-digital converted timing signals across noisy engine bay environments. Use Value: Propagation delay variation ≤2 ns across temperature ensures sub-degree crank angle resolution; 125 °C rating sustains operation near exhaust manifolds. |
| LED Lighting Driver Control | Infotainment Button Panel |
|

IC Role / Device Role / Timing Role: Level-shifting gate driver interface-translates 1.8 V MCU PWM outputs to 5 V-compatible enable inputs on LED drivers. Use Value: 5.5 V input tolerance allows direct connection to 5 V LED driver supply; ±24 mA drive ensures fast turn-on/turn-off of enable lines. |
Use Scenario: Debouncing and translating tactile button inputs from a 5 V panel to a 3.3 V infotainment SoC with integrated GPIO. IC Role / Device Role / Timing Role: Input conditioner-converts mechanical switch transitions into clean, glitch-free digital signals for real-time UI response. Use Value: Schmitt-trigger hysteresis rejects EMI-induced false triggers; AEC-Q100 qualification guarantees long-term reliability in dashboard assemblies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G34QDCURQ1 | TI variant with identical pinout, same AEC-Q100 Grade 1 rating, but higher ICC max (10 μA vs 4 μA) and no JESD8-7 compliance. | Preferred where TI ecosystem integration or legacy design reuse is required; less suitable for ultra-low-power 1.65 V systems. | Select when sourcing from TI-authorized channels or when matching existing TI-based BOMs; verify 1.65 V static performance against Nexperia spec. |
| 74LVC3G34DP-Q100 | Same die, TSSOP8 (SOT505-2) package-0.2 mm wider body (3.0 mm vs 2.3 mm), 0.1 mm longer leads, identical electrical specs. | Better suited for manual rework or wave soldering; slightly lower thermal resistance than VSSOP8 in high-power-density layouts. | Choose for production lines using TSSOP8 tooling or where board-level thermal margin is constrained; pin-compatible drop-in replacement. |
Compared with SN74LVC3G34QDCURQ1, the 74LVC3G34DC-Q100 offers tighter leakage control at 1.65 V and broader JEDEC standard coverage; versus 74LVC3G34DP-Q100, it provides superior space efficiency and higher density routing capability in compact automotive modules.

FAQ
Does 74LVC3G34DC-Q100 support true bidirectional signal translation?
No. It is a unidirectional non-inverting buffer only-inputs accept signals, outputs drive loads. Bidirectional translation requires dedicated level translators like TXB0108 or 74AVCH series devices. This part's overvoltage-tolerant inputs enable 5 V→3.3 V translation, but not reverse direction.
Can this device operate reliably at 1.65 V supply with 5 V inputs?
Yes. Per datasheet Table 6 and Section 1, inputs tolerate up to 5.5 V regardless of VCC. At 1.65 V supply, VIH is 0.65×VCC (1.07 V min), VIL is 0.35×VCC (0.58 V max), and output swing meets specification-validated per JESD8-7 for 1.65–1.95 V operation.
What is the maximum capacitive load this buffer can drive without timing degradation?
Test data in Table 10 specifies 30 pF (for 1.65–2.7 V) and 50 pF (for 3.0–5.5 V) loads. Driving >50 pF increases propagation delay nonlinearly and may cause overshoot; for >100 pF, add series termination or consider higher-drive alternatives like 74LVC2G34.
Is pin 1 location consistent between SOT765-1 (DC) and SOT505-2 (DP) packages?
Yes. Both packages place pin 1 at the lower-left corner beneath the marking code ("Y34" for DC, "V34" for DP), with identical pin numbering and functional mapping-ensuring full PCB footprint compatibility except for body width and lead length differences.
