Product details
Overview
74LVC2G34GXZ from Nexperia is a dual non-inverting buffer gate with Schmitt-trigger inputs, designed for level translation between 3.3 V and 5 V logic domains. It features IOFF partial power-down protection, ±24 mA output drive at 3.0 V, and operates across -40 °C to +125 °C. Used in mixed-voltage I/O interfacing on industrial control PCBs and sensor signal conditioning modules.
For engineers reviewing the 74LVC2G34GXZ datasheet, 74LVC2G34GXZ pinout, 74LVC2G34GXZ application, or 74LVC2G34GXZ equivalent, this page delivers verified package mapping (SOT1255-2), confirmed Schmitt-trigger input thresholds, IOFF leakage specs, propagation delay vs. VCC curves, and real-world level-shifting use cases - all extracted from Nexperia's Rev. 13 product data sheet.
Technical Context
The device implements two independent CMOS buffer stages with hysteresis-enabled Schmitt-trigger inputs, enabling robust operation with slow-rising or noisy signals. Each channel provides true non-inverting logic transfer (L→L, H→H) with rail-to-rail output swing.
IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ≤±2 μA - critical for hot-swap and multi-rail power sequencing. Input overvoltage tolerance up to 5.5 V allows safe interfacing with 5 V TTL sources even when powered from 1.65 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.65 V to 5.5 V - supports single-supply operation across LVC logic families and mixed-voltage board designs |
| Input hysteresis | Typ. 0.3 V at VCC = 3.3 V - rejects noise on slow edges without external RC filtering |
| tpd (VCC = 3.3 V) | 2.2 ns (typ), 5.1 ns (max) - enables timing-critical signal buffering in high-speed digital interfaces |
| Output drive (VCC = 3.0 V) | ±24 mA - drives 50 Ω transmission lines or multiple 74LVC inputs directly |
| IOFF leakage (VCC = 0 V) | ≤±2 μA - prevents destructive current flow during partial power-down sequences |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood industrial and extended-temperature embedded applications |
| ESD rating (HBM) | >2000 V - withstands handling and board-level ESD events per JS-001 Class 2 |
Pinout & Package
X2SON6 package (SOT1255-2): plastic thermal-enhanced extremely thin small outline, no leads, 6 terminals, body size 1.0 × 0.8 × 0.32 mm, exposed thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 2A | Second buffer input - accepts 0–5.5 V logic regardless of VCC; Schmitt-triggered |
| 2 | 1A | First buffer input - identical electrical behavior to Pin 1; independent channel |
| 3 | 2Y | Second buffer output - rail-to-rail CMOS output, IOFF-protected when VCC = 0 V |
| 4 | GND | Digital ground reference - must be low-impedance connection for noise immunity and IOFF function |
| 5 | VCC | Supply voltage input - powers both buffers; IOFF activation occurs when VCC = 0 V |
| 6 | 1Y | First buffer output - electrically isolated from 2Y; supports independent load driving |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (1.65–5.5 V) | Enables direct replacement across legacy 3.3 V and modern ultra-low-voltage systems without redesign |
| Overvoltage-tolerant inputs (to 5.5 V) | Eliminates need for external level-shifters when connecting 5 V microcontrollers to 1.8 V FPGA I/O banks |
| Schmitt-trigger inputs | Reduces susceptibility to ground bounce and crosstalk in dense PCB layouts with long trace runs |
| IOFF partial power-down | Allows safe insertion/removal of daughterboards while main system remains powered |
| JEDEC-compliant standards | Validated for 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) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G34DBVR | Same logic function and IOFF, but SOT-23-6 package (SOT23-6); higher thermal resistance (θJA = 230 °C/W vs. 190 °C/W for SOT1255-2) | Better suited for prototyping and hand-soldering; less optimal for high-density automated assembly | Select when manual rework or breadboarding is required; avoid in thermally constrained 2-layer boards |
| 74LVC2G17GW | Identical SOT363-2 package and Schmitt-trigger inputs, but lacks IOFF circuitry | Not suitable for partial power-down or hot-swap scenarios where VCC may float | Choose only for cost-sensitive, always-powered applications with stable rail sequencing |
Compared with SN74LVC2G34DBVR, 74LVC2G34GXZ offers superior thermal performance and smaller footprint; versus 74LVC2G17GW, it adds essential IOFF protection for modern power-gated systems - making it the only option qualified for dynamic rail management in industrial edge nodes.

FAQ
Does 74LVC2G34GXZ support 1.2 V supply operation?
No. The absolute minimum supply voltage is 1.65 V per JEDEC JESD8-7 compliance. Operation below 1.65 V risks undefined logic states, increased propagation delay variation, and failure to meet VIH/VIL thresholds. For 1.2 V systems, consider the NX3LV240 or 74AUP2G34 families instead.
Can Pin 4 (GND) be left unconnected if using only one buffer channel?
No. GND must be solidly connected to the system ground plane. Leaving it open violates the recommended operating conditions, disables IOFF functionality, degrades noise immunity, and risks latch-up due to floating substrate potential - even with only one channel active.
What is the maximum capacitive load the 74LVC2G34GXZ can drive at 5.5 V supply?
At VCC = 5.5 V, the device maintains tpd ≤ 4.0 ns (max) into 50 pF loads per output, as verified in Table 10. Driving >50 pF increases propagation delay nonlinearly and may cause overshoot; for >100 pF, add a series resistor (22–47 Ω) near the output to dampen ringing.
Is the thermal pad on SOT1255-2 (X2SON6) electrically isolated?
Yes. The exposed thermal pad in the SOT1255-2 package is not connected to any internal die structure or terminal. It may be soldered to a copper pour for thermal relief but must remain electrically floating - no DC or AC connection to GND, VCC, or signal nets is permitted or functional.
