Product details
Overview
74LVC1G34GV-Q100 from Nexperia is a single non-inverting buffer IC with Schmitt-trigger inputs, IOFF partial power-down support, and AEC-Q100 Grade 1 automotive qualification. It operates from 1.65 V to 5.5 V, accepts 5.5 V-tolerant inputs, delivers ±24 mA output drive at 3.0 V, and functions across –40 °C to +125 °C. It serves as a level translator and noise-immune signal conditioner in automotive body control modules.
For engineers reviewing the 74LVC1G34GV-Q100 datasheet, 74LVC1G34GV-Q100 pinout, 74LVC1G34GV-Q100 application, or 74LVC1G34GV-Q100 equivalent, key selection criteria include IOFF-enabled power sequencing, Schmitt-trigger input hysteresis for slow-edge signals, wide VCC range compatibility, and automotive-grade thermal and ESD robustness (HBM >2000 V, CDM >1000 V).
Technical Context
This device implements a single-channel CMOS buffer with Schmitt-trigger input circuitry that provides defined switching thresholds and immunity to slow-rising/falling waveforms. Its IOFF feature actively disables output leakage during partial power-down, preventing backflow current when VCC = 0 V.
The logic function is transparent (Y = A), with propagation delays as low as 0.5 ns at 5.5 V and 25 °C, and static input thresholds scaling with VCC (e.g., VIH = 0.7 × VCC at 4.5–5.5 V). It complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 for multi-voltage interface interoperability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65 V to 5.5 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| Input Voltage Range | –0.5 V to 5.5 V - supports overvoltage-tolerant operation up to 5.5 V regardless of VCC |
| Output Drive | ±24 mA at VCC = 3.0 V - sufficient to drive moderate capacitive loads and multiple CMOS/TTL inputs |
| Propagation Delay | 0.5 ns (min) to 4.1 ns (max) at VCC = 3.0–3.6 V - ensures timing-critical signal buffering with low latency |
| IOFF Leakage | ±2 μA max at VCC = 0 V - guarantees safe bus isolation during power sequencing or hot-swap events |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive environments per AEC-Q100 Grade 1 |
| ESD Robustness | HBM >2000 V, CDM >1000 V - meets stringent automotive board-level ESD requirements |
Pinout & Package
74LVC1G34GV-Q100 uses the SC-74A (SOT753) surface-mount package: plastic, 5-terminal, 1.7 mm × 1.3 mm body, 0.65 mm lead pitch, and 0.26 mm nominal thickness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Not connected (n.c.) | No internal connection; must be left floating or grounded per PCB layout best practice |
| 2 | Data input (A) | Schmitt-triggered input accepting 0–5.5 V; enables reliable switching with slow edges |
| 3 | Ground (GND) | Reference node for all voltage measurements and return path for output current |
| 4 | Data output (Y) | CMOS-compatible buffered output with rail-to-rail swing and ±24 mA drive capability |
| 5 | Supply voltage (VCC) | Primary power rail; IOFF circuitry activates automatically when VCC = 0 V |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from –40 °C to +125 °C ambient, including lifetime reliability testing |
| Schmitt-trigger inputs | Provides hysteresis (typically 0.3–0.5 V) to reject noise and ensure clean transitions on slow-rising signals |
| IOFF partial power-down | Disables output and blocks backflow current when VCC = 0 V, enabling safe multi-rail system power sequencing |
| 5.5 V-tolerant inputs | Accepts input voltages up to 5.5 V independent of VCC, simplifying mixed-voltage translation without external resistors |
| Low dynamic power | CPD = 15 pF - minimizes switching power dissipation in high-frequency signal paths (e.g., sensor data lines) |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G34DRYR | Non-automotive grade; rated –40 °C to +85 °C only; no AEC-Q100 qualification; identical electrical specs otherwise | Limited to industrial/commercial systems without automotive temperature or reliability requirements | Select when cost sensitivity outweighs automotive qualification needs and ambient stays ≤ +85 °C |
| 74LVC1G17GV-Q100 | Same package and AEC-Q100 Grade 1 rating, but includes Schmitt-trigger inputs only - no IOFF circuitry | Suitable where power sequencing is not required but higher noise immunity is critical | Choose when input hysteresis is prioritized over partial power-down functionality |
Compared with SN74LVC1G34DRYR, the 74LVC1G34GV-Q100 adds automotive qualification and extended temperature support; compared with 74LVC1G17GV-Q100, it trades Schmitt-only input behavior for IOFF-enabled system-level power management - making it uniquely suited for mixed-rail automotive subsystems requiring both noise resilience and safe power sequencing.

FAQ
What is the purpose of the n.c. pin (Pin 1) on the 74LVC1G34GV-Q100?
Pin 1 is internally not connected and serves no electrical function. It may be left unconnected or tied to GND for mechanical stability or thermal relief, but must never be driven or used as a signal path. This design choice allows package reuse across variants while maintaining pin compatibility with other SC-74A logic devices.
Can the 74LVC1G34GV-Q100 interface directly between a 5 V microcontroller and a 1.8 V FPGA?
Yes - its 5.5 V-tolerant inputs accept 5 V logic levels regardless of VCC, and its output swings rail-to-rail (0 V to VCC). When powered at 1.8 V, it correctly drives the FPGA input while safely receiving the 5 V signal without clamping diodes or level-shifters.
How does the IOFF feature behave during power-down sequences?
When VCC drops to 0 V, the IOFF circuitry automatically disables the output stage, limiting I/O leakage to ≤ ±2 μA. This prevents current backflow from live buses into the unpowered IC, protecting upstream drivers and meeting ISO 11898-2 requirements for CAN node power sequencing.
Is the Schmitt-trigger input threshold fixed or VCC-dependent?
The Schmitt-trigger thresholds scale with VCC: typical hysteresis is ~0.4 V at 3.3 V, increasing linearly to ~0.7 V at 5.5 V. Input switching points are VIH ≈ 0.7 × VCC and VIL ≈ 0.3 × VCC, ensuring consistent noise margin across the full 1.65–5.5 V supply range.
