Product details
Overview
74LVC1G34GW-Q100 from Nexperia is an automotive-grade single non-inverting buffer with Schmitt-trigger inputs, IOFF partial power-down support, 1.65 V to 5.5 V supply range, ±24 mA output drive at 3.0 V, and AEC-Q100 Grade 1 qualification (−40 °C to +125 °C). It enables level translation between 3.3 V and 5 V logic domains in body control modules and infotainment interfaces.
For engineers reviewing the 74LVC1G34GW-Q100 datasheet, 74LVC1G34GW-Q100 pinout, 74LVC1G34GW-Q100 application, or 74LVC1G34GW-Q100 equivalent, key selection criteria include IOFF-enabled power sequencing, Schmitt-trigger noise immunity for slow-rising sensor signals, wide-VCC tolerance for mixed-supply systems, and TSSOP5 package suitability for space-constrained automotive PCBs.
Technical Context
This device implements a single-channel CMOS buffer with hysteresis on the input (Schmitt-trigger), enabling robust operation with slow or noisy digital signals such as those from mechanical switches or analog comparators. The 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 and modern logic families. Input voltage tolerance up to 5.5 V allows direct connection to 5 V TTL sources without external clamping.
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 domains |
| Input Voltage Tolerance | Up to 5.5 V - enables safe connection to 5 V TTL outputs without level-shifting circuitry |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple LVC loads or small capacitive traces |
| Propagation Delay | 0.5 ns (min) to 5.2 ns (max) at VCC = 3.0–3.6 V - ensures timing compliance in sub-10 ns signal paths |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - limits backfeed current during hot-swap or partial-power-down sequences |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cabin electronics |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive ESD robustness requirements for assembly and field operation |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm lead pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - must be left unconnected; no routing or thermal tie required |
| 2 | A | Data input with Schmitt-trigger hysteresis - accepts slow-rising signals down to 10 ns/V slew rate |
| 3 | GND | Ground reference for all I/O and supply - requires low-inductance connection to system ground plane |
| 4 | Y | Inverting-buffered output - delivers rail-to-rail CMOS-compatible logic levels with ±24 mA sink/source |
| 5 | VCC | Primary supply input - must be decoupled locally with ≥100 nF ceramic capacitor near pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables reliable switching with slow or noisy inputs (e.g., door switch debouncing), eliminating need for external RC filtering |
| IOFF partial power-down | Prevents damaging back-current flow when VCC is off but input/output nodes remain biased - critical for hot-plug subsystems |
| Overvoltage-tolerant inputs | Accepts 5.5 V inputs while powered from 1.65 V - eliminates external clamping diodes in mixed-voltage designs |
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with full parametric testing - meets automotive reliability and lifetime requirements |
| Low dynamic power dissipation | CPD = 15 pF - minimizes switching power in high-frequency clock distribution or data buffering applications |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G34QDBVRQ1 | TI part in SOT-23-5; identical logic function and AEC-Q100 Grade 1 rating; IOFF and Schmitt-trigger supported; max VCC = 5.5 V; slightly higher ICC (6 μA vs 4 μA) | Same automotive temperature range; different package thermal resistance (SOT-23-5 RθJA ≈ 210 K/W vs TSSOP5 ≈ 190 K/W) | Select when existing TI design ecosystem or preferred distributor stock favors TI packaging |
| 74LVC1G34GV-Q100 | Nexperia SC-74A (SOT753) variant; same electrical specs and qualification; 3.1 mm × 1.7 mm footprint vs TSSOP5's 2.2 mm × 1.3 mm; no pin 1 notch - marking-based orientation only | Same functional behavior; lower profile (1.1 mm vs 1.1 mm) but wider body; less suitable for ultra-dense layouts | Select when board assembly uses SC-74A placement tooling or requires alternate thermal mass profile |
Compared with SN74LVC1G34QDBVRQ1, the 74LVC1G34GW-Q100 offers tighter supply current (4 μA vs 6 μA) and smaller TSSOP5 footprint; versus 74LVC1G34GV-Q100, it provides superior board-area efficiency and standardized pin-1 indexing for automated optical inspection.

FAQ
Does the 74LVC1G34GW-Q100 support true bidirectional level shifting?
No. It is a unidirectional buffer: input A drives output Y only. While its overvoltage-tolerant inputs accept 5.5 V signals regardless of VCC, the output Y is always referenced to VCC and cannot source/sink current into a higher-voltage domain. For bidirectional translation, discrete solutions or dedicated bus switches are required.
Can pin 1 (n.c.) be used as a thermal pad or ground tie?
No. Pin 1 is internally not connected - no bond wire or die attachment exists. Routing it to GND or using it for thermal conduction provides no electrical or thermal benefit and may risk solder bridging or misalignment during reflow. Leave it floating and unconnected per Nexperia's recommended layout.
What is the minimum input slew rate this device can reliably handle?
At VCC = 2.7 V to 5.5 V, the device guarantees proper switching with input transition rates as low as 10 ns/V (i.e., 10 V/ns maximum slew). This corresponds to rise/fall times up to ~200 ns for a 2 V swing - sufficient for mechanical switch inputs and low-speed sensor outputs without external conditioning.
How does IOFF behave when VCC is ramping during power-up?
IOFF activates only when VCC falls below ~0.8 V (per characterization data), remaining inactive during normal power-up. Output Y follows input A throughout VCC ramping from 0 V to operating voltage. IOFF is not intended for power-rail sequencing control but for safe isolation after full power removal.
